Chapter 1 Overview of Softek AdvancedCopy Manager
This chapter describes the overview of Softek AdvancedCopy
Manager.
1.1 What is Softek AdvancedCopy Manager?
Softek AdvancedCopy Manager is a product that realizes storage
management in an open system and provides the following
solutions.
1.1.1 High-speed backup (24-hour basis)
A hardware function [Advanced Copy Function (OPC, EC)] of Fujitsu's
disk array units (ETERNUS/GR Series) is used to back up data fast.
The advanced copy function, being a fast data copy function
independent of a data size, can always maintain fixed backup time
even if the data to be backed up increases. Thus, the backup time
does not increase even if the data amount increases.
This function can drastically reduce the time in which work must be
stopped to perform backup.
In addition, since operations management is linked to the following
DBMS, high-speed backup can be performed without interruption to
daily work. · Oracle If work uses a database other than Oracle or
uses a general file system, the time that work is interrupted is
still significantly reduced.
In addition, operations management can be used as a remote copy
function for remote sites to create remote copies between Fujitsu
disk array units on a SAN-WAN-SAN connection. Remote copying can
also provide a disaster recovery solution because disk arrays
containing backup data can be stored in an earthquake-resistant
location.
1.1.2 Non-stopped operating backup [database]
By using Softek AdvancedCopy Manager, the database of Oracle and
SQL Server can be backed up by no operating stopping. Please refer
to an Appendix B "Sample Shell script for Backup Operations" about
the backup method of the database of Oracle.
Moreover it can back up in Softek AdvancedCopy Manager, without
cooperating with SynfinityDISK and stopping SynfinityDISK also
under mirror volume (SDX object) environment.
1.1.3 High-speed replication
The hardware function (advanced copy function [OPC/EC]) of the
Fujitsu disk array unit (ETERNUS/GR Series) enables data to be used
for purposes other than the original purpose and replicated data
(copy) to be collected as a protection against data
corruption.
If recovery from a disaster is necessary, replication (copying) can
be performed for disk array units located at a remote site that has
an SAN environment.
1.2 Product Configuration of Softek AdvancedCopy Manag er
1.2.1 Function system
[Table 1.1 Functions]
Function name Description
Manager of Softek AdvancedCopy Manager
Operates on the Storage management server, and two or more Storage
servers are managed. Backup management and replication management
are performed.
Agent of Softek AdvancedCopy Manager
Operates on the Storage server with which the storage device is
connected. Backup management and replication management are
performed.
1
This product is used combining the manager of Softek AdvancedCopy
Manager of the Solaris OE version, the Windows version, or the
Linux version.
· This product, which is included as a component of the SP5000
Basic Package, enables integrated backup in
the SP series. For more information on the SP series, see the
Storage Management Processor Operator's Manual.
· The Manager product includes the Agent function. The Softek
AdvancedCopy Manager server type depends on the operating
environment. · Storage server
The Storage server is a server which executes the backup business
and the replication business that AdvancedCopy Manager offers. The
Agent of softek AdvancedCopy Manager is introduced into the Storage
server. However, only when the Storage server is one, the Manager
of Softek AdvancedCopy Manager is introduced on the system.
· Storage management server The Storage management server manages
the Storage servers and only one Storage management server can be
set in the system. The Manager of softek AdvancedCopy Manager is
introduced into the Storage management server.
Three operating environment forms shown below can be built with the
number of the Storage servers which can be used by operating of
Softek AdvancedCopy Manager. · When only one Storage server is
set
In this operating environment, only Manager of AdvancedCopy Manager
needs to be installed (Manager of AdvancedCopy Manager includes the
Agent functions of AdvancedCopy Manager).
[Figure 1.1 When only one Storage server is set]
· When two or more Storage servers are set
When two or more AdvancedCopy Manager servers are available, set
only one of them up as the Storage management server or set up a
new server with no disk drive connected as the Storage management
server. Each operation environment is explained below.
a. When the Storage server is operated as a Storage management
server One of the servers functions as a Storage management server.
The Storage management server has a repository where the
information on operating and management of all Storage servers is
stored. When many Storage servers exist, all of them compete for
accesses to the repository. This will affect other applications
running on to the same server. Therefore, the Storage management
server should be considered as a dedicated server. When a special
Storage management server cannot be prepared with the system
configuration, becomes an operation form shown in Figure 1.2. (One
Storage management server and others become a Storage
server.)

1.3 Function Overview of Softek AdvancedCopy Manager
1.3.1 What is the backup function?
The backup function of Softek AdvancedCopy Manager provides
operation management for high-speed backup by using the OPC (One
Point Copy) function of a Fujitsu disk array unit (ETERNUS3000,
GR720, GR730, GR740) and the ROPC (Remote One Point Copy), EC
(Equivalent Copy), and REC (Remote Equivalent) functions of a
GR740, GR820 and GR840.
This function realizes the following backup operation:
+High-speed backup operation
The advanced copy function (OPC/EC function) of the disk array unit
is used to perform high-speed backup between volumes regardless of
volume capacities. This function drastically reduces the length of
time that work is inevitably interrupted during backup.
+Backup operation in the SP series
SP series products work closely with GR series disk array units in
the management and operation of storage that is independent of the
server.
With Softek AdvancedCopy Manager, a backup/restore function linked
to the backup function of the SP series is provided so that SP
series disks can be integrated in the same way that volumes of
other GR series disk array. This function is in addition to the
management of SP series disks already available in the SP
series.
+Cooperation with ISV software (sample scripts)
Sample scripts with the following functions are provided. These
scripts consist of Softek AdvancedCopy Manager
5
commands, a DBMS, and backup software commands. · Acquisition of
DBMS (Oracle) resource information · Synchronization with a DBMS
(Oracle), copying of volumes, and saving of copy destination
volumes to tape
(NetBackup, NetWorker, TivoliStorageManager) Additionally, the
following functions allow you to manage the backup operation.
+Policy management function
The policy management function manages the number of preservation
generations of backup and the number of interval days in which
backup should be performed (displays the delay when displaying
information) for a volume to be backed up.
+Storage configuration management function
The storage configuration management function manages the
configurations of volumes to be backed up and volumes to which a
backup should be saved.
On Softek AdvancedCopy Manager, a volume to be backed up is called
a transaction volume; a volume to which a backup should be saved is
called a backup volume.
+Backup and restore functions
The backup and restore functions back up and restore a specified
volume.
· The backup function with ROPC/REC is available only for backup
disk array units on the same storage server.
+History information management function
The history information management function manages, out of the
information that has been backed up in the past, the information in
preservation generations as history.
+Consistency recovery function
The consistency recovery function resolves inconsistencies in the
Softek AdvancedCopy Manager backup management information caused by
a system or other type of failure.
1.3.2 What is the replication function?
The replication function of Softek AdvancedCopy Manager provides
operation management of replications by using the OPC (One Point
Copy) function of a Fujitsu disk array unit (ETERNUS3000, GR720,
GR730, GR740) and the ROPC (Remote One Point Copy), EC (Equivalent
Copy), and REC (Remote Equivalent) functions of the GR740, GR820
and GR840.
As a result, the following replication operations become
possible.
+High-speed replication operation
The advanced copy function (OPC/EC function) of the disk array unit
is used to perform high-speed replication between volumes
regardless of volume capacities. This function drastically reduces
the length of time that work is inevitably interrupted during
replication.
Since this function, unlike the backup function, does not manage
histories, it is suitable for temporary backup. In addition, when
the replication function is used with EC, this kind of replication
can also be used as an update (incremental) backup operation.
+Consistency recovery function
The consistency recovery function resolves inconsistencies in the
Softek AdvancedCopy Manager replication management information
caused by a system or other type of failure.
1.3.3 Authentication feature function
In relation to the backup function provided by Softek AdvancedCopy
Manager, this function manages users who have acquired access
rights, providing security controls in the identification of
function users. For more information, see Chapter 3, "Security
Operation Using Authentication Feature". Note also that the
replication function is not a target of the authentication
feature.

1.3.4 Web client screen
At Softek AdvancedCopy Manager, they are an environmental setup and
employment. It is possible to carry out on a Web client screen. The
main functions are as follows. · Security management
Operation restrictions of the user of Softek AdvancedCopy Manager
can carry out by GUI operation. · Backup management
Employment (a definition of a server or a device, backup,
restoration, etc. to employ) of backup management of Softek
AdvancedCopy Manager can carry out by GUI operation.
By the web browser, a Web client screen can be used by accessing a

Chapter 4 Backup Operations (Normal Transaction Volumes
This chapter explains backup operations for normal transaction
volumes of Softek AdvancedCopy Manager.
4.1 Overview
This chapter describes the backup and restore functions of Softek
AdvancedCopy Manager.
Softek AdvancedCopy Manager performs high-speed backup between
volumes, regardless of the volume capacities, using the advanced
copy function (OPC or EC function) of a disk array unit.
Backup that uses the One Point Copy (OPC) or Remote One Point Copy
(ROPC) function of a GR series disk array unit is called snapshot
fast backup. Backup that uses the Equivalent Copy (EC) or Remote
Equivalent Copy (REC) function is called synchronized high-speed
backup.
Automatic snap shot backup can be scheduled without first
estimating the time required because it does not require backup
synchronous processing. Note, however, that when the save number is
1, a state in which there is no backup data may occur, because a
snap shot backup deletes the history prior to copy
processing.
Because synchronized high-speed backup deletes the history after
the completion of backup processing, there is no status in which
backup data does not exist even though the generation number is 1.
However, synchronized high-speed backup requires one more backup
volume than snapshot fast backup. Synchronized high-speed backup
also requires synchronized backup processing before the backup
execution command is entered. Therefore, execution of automatic
synchronized high-speed backup must be scheduled so that the time
required for synchronized processing is estimated in advance.
Synchronized backup processing is then started based on the
estimated time, and the backup execution command is entered after
equivalency maintain status has been achieved.
Softek AdvancedCopy Manager automatically manages and selects a
medium to be used for backup (a backup volume).
Softek AdvancedCopy Manager also manages the backup carriers and
generations and allows you to restore data from the latest or other
past generations.
[Figure 4.1 Managing a backup volume]
4.1.1 Snapshot backup processing
The OPC (One Point Copy) /ROPC (Remote One Point Copy) function of
the disk array unit GR series is used to copy data from a
transaction volume to an unused backup volume.
The snapshot fast backup performs processing as follows: 1. Execute
the backup execution command ((1) in Figure 4.2). The following
processing will be performed: - If backup volumes under generation
management exist for all the generations, the oldest backup
volume will be assumed as an unused backup volume.
15
- An unused backup volume will be acquired from the unused backup
volume management area. 2. Data on the transaction volume will be
copied to the acquired unused backup volume ((2) to (4) in Figure
4.2). 3. Backup carrier information will be set.
[Figure 4.2 Snapshot fast backup processing]
The snapshot fast backup is completed as soon as you specify to
execute backup. The actual data copying will be internally
performed by the OPC function of the disk array unit GR
series.
· If all generations of backup volumes are managed, and if no
backup volume can be obtained from the unused
region in the backup volume management area, backup copies cannot
be created. · The backup function which used ROPC is restricted to
the disk array equipment in the same Storage server.
4.1.2 Synchronized high-speed backup processing
The Equivalent Copy (EC) or The Remote Equivalent Copy (REC)
function of the GR series of disk array units is used to copy data
from a transaction volume to an unused backup volume.
Synchronized high-speed backup performs processing as follows: 1.
Execute the backup synchronized processing start command ((1) in
Figure 4.3). An unused backup volume
having the same capacity as the transaction volume is selected from
the unused backup management area, and the synchronized backup
processing starts.
2. The transaction and backup volumes are both placed in
equivalence status. From this point on, equivalence between the
transaction volume and backup volume is maintained. This status is
referred to as equivalency maintain status ((3) in Figure
4.3).
3. Execute the backup execution command ((4) in Figure 4.3). The
backup synchronization processing stops and the backup history
information is set.
4. If the backup data exceeds the number of generations when backup
has been completed, the oldest backup volume is treated as an
unused backup volume.
16
The backup execution command cannot be executed before the
transaction and backup volumes have become equivalent.
[Figure 4.3 Backup using the synchronized high-speed backup
function]
· If all generations of backup volumes are managed, and if no
backup volume can be obtained from the unused
region in the backup volume management area, backup copies cannot
be created. · The backup function which used ROPC is restricted to
the disk array equipment in the same Storage server.
4.1.3 Restoration processing
This chapter describes restoring data on Softek AdvancedCopy
Manager.
The restoration operation refers to restoring data from a backup
volume managed by the backup carrier information to a transaction
volume.
The restoration operation from a backup volume refers to using the
OPC function provided by the disk array unit to restore data from a
backup volume to a transaction volume.
If the data on a backup volume under carrier management is restored
to a transaction volume, the carrier management information will
not change.
Note that data will be restored to a transaction volume that is the
backup source. However, you can change the restoration
destination.
17
If transaction volume contents are rewritten in the period between
collection of the latest backup volume and a subsequent restore
operation, rewritten data is not assured.
[Figure 4.4 Notes on restore operations in Softek AdvancedCopy
Manager]
4.2 Operation Design
This chapter describes the backup operation on Softek AdvancedCopy
Manager.
Design a backup operation as follows: · Deciding a server on which
the backup operation should be performed · Deciding a backup target
· Deciding a backup policy · Preparing a backup volume · Preparing
the automatic backup operation
4.2.1 Deciding a server on which the backup operation should be
performed
Determine the server that will be used to perform backup.
The following servers can be used to perform backup: · Storage
management server
Multiple storage servers are unified and operated centrally. The
storage management server can also be used as a storage
server.
· Storage server Softek AdvancedCopy Manager operations are
performed.
The locale of the internal code system (code system specified when
installing Softek AdvancedCopy Manager on the Storage management
server) used by Softek AdvancedCopy Manager must be installed on
all Storage servers.
18
[Figure 4.5 Configuration of servers on which the backup operation
should be performed]
4.2.2 Deciding a backup target
Softek AdvancedCopy Manager backs up data in units of slices. A
slice that stores work data is called a transaction volume. A
transaction volume to be backed up must be placed on the disk array
unit GR series.
For information on setting up a transaction volume, see Chapter
4.4.8, "Setting the operation type for a device".
Slices must be allocated for transaction volumes in the following
manner:
· Create slices so that no VTOC is contained in them. · No slice
may be duplicated on the same disk.
For backup targets, do not select slices in which a system is
stored or Softek AdvancedCopy Manager is installed.
For any slice that defines an entire volume, do not register it as
a transaction volume.
No file system of SynfinityFILE consisting of multiple slices can
be processed. When backing up or
19
restoring a file system of SynfinityFILE consisting of multiple
slices, handle the multiple slices at the same time while they are
unmounted.
4.2.3 Deciding a backup policy
To setup a backup policy on a transaction volume, set the following
items:
+Number of preservation generations
The number of preservation generations refers to how many
generations of backup data should be kept.
The snapshot fast backup first releases the oldest generation from
the generation management. If a system failure or any other failure
occurs while the backup is running, there may not be as many
generations of backup data as required. In such a case, you are
recommended to perform backup immediately again.
By snapshot type high-speed backup, when employing the number of
preservation generations as 1, we recommend you to use together the
employment which evacuates backup data to a tape etc.
A synchronous high-speed backup operation releases the oldest
generation from generation management after backup of the latest
generation is completed. Thus, backup volumes for (number of backup
generations + 1) are necessary.
+Interval days
The interval days refers to an interval at which backup should be
performed.
The delay of backup is displayed if more days than the specified
number of interval days have passed after the last backup
date.
Note that backup is not performed periodically even if you have
specified the interval days.
For information on setting a backup policy, see Chapter 4.4.10,
"Setting a backup policy".
4.2.4 Preparing a backup volume
Prepare the backup volume.
The backup unit of Softek AdvancedCopy Manager is a slice. In
Softek AdvancedCopy Manager, the slice in which the transaction
data used as the candidate for backup is stored is called
transaction volume.A backup volume must be placed on the disk array
unit GR series.
The backup volume size must equal the transaction volume size. The
number of backup volumes used for snapshot-type high-speed buffer
operations and that for synchronous high-speed buffer operations
are listed below:
Backup Number of required backup volumes
For snapshot fast backup Number of backup generations
For synchronized high-speed backup Number of backup generations +
1
When backup policies have already been set for multiple transaction
volumes, the registration of a backup policy for a newly registered
transaction volume requires that the following number of backup
volumes be registered beforehand:
Backup Number of required backup volumes
For snapshot fast backup
Total number of backup generations in the registered backup
policies + number of generations in the new backup policy being
set
For synchronized high-speed backup
Total number of backup generations in the registered backup
policies + number of registered transaction volumes + number of
generations in the new backup policy being set + 1
Slices must be allocated for backup volumes in the following
manner: · Create slices so that no VTOC is contained in them. · No
slice may be duplicated on the same disk. In a backup volume, there
is no need to create a slice that
indicates a whole volume, such as slice2.
20
For backup volumes, do not select disks in which a system is stored
or Softek AdvancedCopy Manager is installed.
For information on setting a backup volume, see Chapter 4.4.8,
"Setting the operation type for a device".
4.2.5 Preparing the automatic backup operation
The backup operation of Softek AdvancedCopy Manager can be
automated using SystemWalker/OperationMGR, etc.
+Automatic snapshot fast backup
Automatic snapshot fast backup can be executed in one of the
following two ways. · Start the backup command in a job net of a
batch job every time when a backup should be collected.
· Start the backup command at the specified time.
+Automatic synchronized high-speed backup
For synchronized high-speed backup, the transaction and backup
volumes must be in equivalency maintain status at the scheduled
time for backup.
For this reason, if synchronized high-speed backup is automated,
the backup synchronous processing start command and the backup
execution command must be started separately, as described
below.
++Starting the backup synchronous processing start command
At first, theoretically calculate the time required for the
synchronized backup processing. Execute the backup synchronous
processing start command by specifying the time obtained by
subtracting that theoretical time or more from the time that the
backup execution command is to start. The transaction and backup
volumes will then be in equivalency maintain status when backup is
executed.
The time between the start of synchronized backup processing and
the transition to equivalency maintain status depends on the
capacity of the volume to be copied.
++Starting the backup execution command
Use either of the following methods to automatically execute the
backup execution command:
21
· Start the backup execution command in a job net of a batch job at
the same time at which the backup data is to be collected.
If there are other jobs (jobs A and B in the figure) to be executed
before the backup execution command in the job net, the start time
of the backup execution command cannot be determined. Assume that
the start time of the backup execution command is the time obtained
by adding the shortest time required for jobs A and B to the job
net start time. Determine the start time of the backup synchronous
processing start command by subtracting the estimated time from the
start time of the backup execution command.
· Start the backup execution command with the time specified.
4.3 Flow of Operation
The following shows the flow of backup operation on a regular
transaction volume.
22
4.4 Preparations
The following preparations are required before the backup operation
is started.
23
4.4.1 Activating daemons
Before the backup operation is started, the daemons of Softek
AdvancedCopy Manager must be started on the storage management
server and the Storage servers. Normally, these daemons are
automatically started up when the system is started. If the startup
of a daemon fails for some reason or if a daemon has been stopped,
you need to start the daemon on each server. For information on
starting a daemon, see Chapter 2, "Starting and Stopping a Daemons
".
4.4.2 Setting an access permission
When performing backup employment from a backup management screen,
an access permission of each operation of a backup management
screen is set up. For details of the Setting Method, see Chapter 3,
"Security Operation Using Authentication Feature".
When only a command performs backup employment, a setup of access
permission is not required.
4.4.3 Starting the initial window
Specify the following URL to start the initial window of Softek
AdvancedCopy Manager.
http://storage-management-server-address(:port-number)/swstorage/index.html
The following GUI (server list view) will be started.
When applying only by the command, without using GUI, it is not
necessary to perform this operation.
4.4.4 Registering a storage server
The Storage management server registers the Storage server to be
managed. When the Storage server is operated as a Storage
management server does not need to add a server.
Select the [Operation] menu; select [Addition of Server]. The
following window will be displayed.
24
For a storage server to be added, specify a server name, IP
address, and port number required for communications. The port
number is specified as the "communications service port number",
when Agent of Softek AdvancedCopy Manager was installed.
In cluster operation, specify the logical IP address of the Storage
server as IP address. And specify the port number registered at the
time of the cluster setup of Storage server transaction.
The [OK] button is pushed after inputting the above item, and
additional processing of a Storage server is carried out.
In addition, this processing can be carried out also by the server
information addition command (stgxfwcmaddsrv).
4.4.5 Fetching device information on a storage server
Before the backup management can be performed, device information
on a storage server must be temporarily stored to the repository.
To acquire information on a device on the storage manager server,
the [Operation] menu, select [Acquisition and reflection of
Information on all devices]. The following window will be
displayed.
Check the server from which device information should be acquired
and then press the [OK] button.
After device information is acquired from each server, the
following dialog will be displayed.
25
The new devices detected will be displayed in the uppermost list
box. Move a device to be managed to the list box on the left. The
second list box displays devices currently under management but not
detected. Move a device that you no longer want to manage to the
list box on the right. The lowermost list box displays devices
whose device information has been updated (e.g., the mount point
name has been changed).
After performing the above operations, press the OK button to
reflect the configuration information.
In addition, this processing can be carried out also by the device
information collection/reflection command (stgxfwcmsetdev).
The time required for this operation is proportional to the total
number of devices defined on the Storage server. If the number of
devices is large, perform this operation while the CPU load and I/O
load are low.
As a guideline for reference, each operation takes about 0.5 s per
device (partition) in a state without load.
4.4.6 Displaying the backup management window
On the server list view, select the [File] menu and then [Backup
Management]. The server list view for the backup management will be
displayed.
26
4.4.7 Setting the environment for a backup operation server
Set the environment for each storage server. From the Backup
Management window, select backup management in the tree displayed
on the left side. Then, select the storage server in a list panel
displayed on the right side of the window. Finally, select [Set
Storage Server Configuration Information] from the [Operation]
menu. The following setup window will be displayed.
If the target Storage server is Solaris and the SymfoWARE database
exists in the Storage server, a recovery control file output place
directory and a work directory are inputted. When a SymfoWARE
database does not exist in a Storage server, or when a Storage
server is WindowsNT/2000, HP-UX or Linux, this input item cannot
serve as a half-tone display, and cannot be inputted.
After completing the input of necessary items, click the [OK]
button.
You need to make this environment setting also on the storage
management server if it serves also as a storage server. This step
is not required if the environment setting has already been made on
the storage servers.
You can also make this environment setting also using the storage
server configuration information setting command.
4.4.8 Setting the operation type for a device
Set up the following device operation type, before backing up in a
storage server. The operation type is as follows: · Define the
volume to be backed up as a transaction volume. · Prepare backup
volumes. Prepare as many partitions, each of which has the same
size as the transaction
volume, as the number required for the backup type, and define them
as the backup volumes:
27
Snapshot fast backup Number of backup generations
Synchronized high-speed backup Number of backup generations +
1
Set an operation type on the server list view. On the server list
view, select a storage server and select the [Operation] menu and
then [Set Device Information]. The following setup window will be
displayed.
A volume displayed in "Other volume" field has no specified device
operation type. Set a device operation type as follows: · Setting
as a "transaction volume"
After selecting a target volume, click the [<] button on the
"Transaction volume" side. The target volume will be moved to the
"Transaction volume" field.
· Setting as a "backup volume" After selecting a target volume,
click the [<] button on the "Backup volume" side. The target
volume will be moved to the "Backup volume" field.
After making settings for all the volumes, click the [OK]
button.
You can make this setting also using the device information setting
command (swstdevinfoset).
For any slice that defines an entire volume, do not register it as
a transaction volume.
If the slice configuration of a transaction volume is changed,
delete the volume from the registered transaction volumes. Next,
after following the process of Fetching device information on a
Storage server again, re-register the volume by executing the
device information setting command.
Backup volume needs to be the same size as operating volume.
28
Please make applicable to backup neither the disk with which the
system is stored, nor the disk with which Softek AdvancedCopy
Manager is installed.
You can check what has been registered as follows: · Checking on a
GUI window
You can view information on a transaction volume on the transaction
volume list view or information on a backup volume on the backup
volume list view. For more information on each of these views, see
the " Windows, Solaris OE or Linux Softek AdvancedCopy Manager
User's Guide".
· Checking using a command You can view information on a registered
transaction volume or backup volume using the device usage status
display command.
4.4.9 Setting options
Set options when performing backup to a backup volume in a cabinet
that is not the same as the cabinet containing the transaction
volume.
Create the following files to set options:
For normal operation (non-cluster)
/etc/opt/FJSVswsts/logical-node-name(*1)/data/DEFAULT/check.ini
(*1) Logical node name of AdvancedCopy Manager specified during
setting up of a cluster.
Code as follows:
RemoteCopy=Yes
· If the option settings file is changed after operation starts,
backup may not be able to continue. For this reason,
do not change the option settings file after the start of
operation. · To change the option settings file, you must set the
backup policy again.
4.4.10 Setting backup policies
For a transaction volume registered on a storage server, set the
following backup policy: · Number of preservation generations
Means how many generations of backup data should be kept. ·
Interval days
Means the number of days before next backup should be performed. If
the specified number of days is exceeded, you will be prompted to
perform backup on the GUI window of Softek AdvancedCopy
Manager.
To set a backup policy on the server list view, you display storage
servers in a tree view on the server list view. The list of
transaction volumes and backup volumes on this storage server will
be displayed. After selecting a transaction volume for which you
want to set a backup policy, click the right mouse button. From the
popup menu, select [Set Backup Policy]. The following setup window
will be displayed.
29
On this window, specify the number of interval days and the number
of preservation generations and click the [OK] button. Perform this
procedure on all the transaction volumes. You can set a backup
policy also using the backup policy setting command
(swstbkpolset).
· Even if the number of interval days has been specified, Softek
AdvancedCopy Manager does not automatically
collect backup. This value is used only to prompt the user to
perform backup when the number of backup interval days is
exceeded.
· When you set a backup policy, there must be as many registered
backup volumes as required to perform backup according to the
specified backup policy. For information on the necessary number of
backup volumes, see Chapter 4.2.4, "Preparing a backup
volume".
· Even though the number of backup volumes required for the backup
may not have been registered beforehand when backup policies for
synchronized high-speed backup were set, the number required can be
set if the number of backup volumes that are required for snapshot
fast backup have been registered. However, synchronized high-speed
backup may not be able to be executed.
You can check what has been defined as follows: · Checking on a GUI
window
You can view information on a backup policy on the transaction
volume list view. For more information on the view, see the "Softek
AdvancedCopy Manager User's Guide".
· Checking using a command You can view information on a defined
backup policy using the backup policy display command
(swstbkpoldisp).
4.4.11 Customizing preprocessing and postprocessing scripts
In the case of one of the two operations explained below, the
backup preprocessing and postprocessing scripts need to be
customized. · When, because of an operational reason, you want to
avoid unmount/mount processing for a transaction
volume where a file system is constructed · When you want to add
special preprocessing and postprocessing to the preprocessing and
postprocessing
scripts Refer to Appendix A, "Preprocessing and Postprocessing of
Backup and Restoration," for details on the customization.
4.4.12 Preparing a device map file
In the backup operation on Softek AdvancedCopy Manager, a backup
volume with the same capacity as a transaction volume is
automatically selected from the registered backup volumes.
If the backup volume is recognized in a "Device map file", i.e., a
file defining the correspondence between transaction and backup
volumes, it must be created.
Create a device map file anywhere on the storage server that
performs backup. If you specify this file while performing backup,
an operation in recognition of the backup destination is
enabled.
30
4.4.12.1 Describing a device map file
The following shows a description example of a device map
file.
The following lists rules for creating a device map file. ·
Describe a transaction volume and a corresponding target backup
volume in one line. Separate a transaction
volume and a backup volume with one or more "half-size blank or tab
characters". One or more "half-size blank or tab characters" may be
included between the beginning of a line and a transaction volume
name or between the end of a backup volume name and the end of a
line (newline character).
· A blank line ("half-size blank or tab characters") may be
included in a file. · The portion from the symbol "#" to the end of
a line is assumed as a comment. · You cannot specify more than one
target backup volumes for one work disk in one device map file. In
such a
case, the information in the line first found will be valid. While
a device map file is read, the system will not detect such a
redundant line.
· A device map file may include descriptions of transaction volumes
other than the processing target (Device-Name or Log-Group-Name).
(See the description example provided in the beginning of this
chapter.)
· When defining output place backup volume to a log group, you have
to carry out description about all operating volumes into a single
file. (Description must not be straddling two or more files.)

This chapter describes backup with the SP Series.
6.1 Overview
In backup management, the volumes that are backed up with linkage
to models of the SP series are managed as transaction volumes under
control of the SP series models.
At the time of performing backup/restore, these volumes are backed
up/restored with models of the SP series.
See the Storage Management Processor Administrator's Guide for
details on how to back up/restore these volumes.
[Figure 6.1 Backup management configuration ]
6.2 Operation Design
Design/set up the backup operation as described below: 1.
Determining the server to perform backup 2. Determining the backup
target 3. Determining a backup policy 4. Preparing a backup
volume
6.2.1 Determining the server to perform backup
Determine the server that will be used to perform backup.
The following servers can be used to perform backup: · Storage
management server
Multiple storage servers are unified and operated centrally. The
storage management server can also be used as a storage
server.
· Storage server
Softek AdvancedCopy Manager operations are performed.
The locale of the internal code system (code system specified when
installing Softek AdvancedCopy Manager on the Storage management
server) used by Softek AdvancedCopy Manager must be installed on
all Storage servers.
48
[Figure 6.2 Example of Storage management server and Storage server
configuration]
6.2.2 Determining the backup target
To perform backup management in linkage with models of the SP
series, define the backup target as a transaction
49
volume of the SP series.
Because the device to be backed up must be managed by a model of
the SP series, system design and setup with respect to the SP
series models must be performed first. See the Storage Management
Processor Administrator's Guide and Storage Management Processor
Installation Guide for details on how to perform system design and
setup with respect to the devices of the SP series.
Specify the devices for which backup is to be performed with the
device information setting command. The setting status with respect
to the devices for which backup is to be performed can be
referenced by the device usage status display command.
Please make applicable to backup neither the disk with which the
system is stored, nor the disk with which Softek AdvancedCopy
Manager is installed.
6.2.3 Determining a backup policy
Set a backup policy for the transaction volume controlled by the SP
series. Do not use Softek AdvancedCopy Manager. Instead, use the SP
series GUI.
See the Direct Backup User's Guide for details on how to set the
backup policy via the SP series GUI.
Because the policy for the transaction volume operated by the SP
series must be set by the SP series GUI, the following commands
cannot be executed for a transaction volume controlled by the SP
series:
· Backup policy setting command · Backup policy display command ·
Backup policy deletion command
6.2.4 Preparing a backup volume
In backup/restore linking with the SP series, a backup volume is
managed by the SP series. When you design/setup the backup volume,
do not use Softek AdvancedCopy Manager. Instead, use the SP series
GUI. For more information about the SP-series GUI, see the Direct
Backup User's Guide.
6.3 Flow of Operation
The following figure shows the flow of backup with the SP
series.
50
Before the start of backup, the following preparations are
required.
6.4.1 Activating daemons
Before starting a backup operation, daemons on the Storage
management server, Storage servers, and SP servers must be
activated. Normally, they are automatically activated.
51
When starting goes wrong for a certain reason, and when a demon is
stopped at once, it is necessary to start a demon by each server.
Please Refer to Chapter 2 "Starting and Stopping daemons" of this
Manual of Demon about Starting of Demon.
6.4.2 Setting an access permission
When performing backup employment from a backup management screen,
an access permission of each operation of a backup management
screen is set up. For details of the Setting Method, see Chapter 3,
"Security Operation Using Authentication Feature".
When only a command performs backup employment, a setup of an
access permission is not required.
6.4.3 Starting the initial window
Specify the following URL to start the Softek AdvancedCopy Manager
initial window:
http://storage-management-server-address(:port-number)/swstorage/index.html
The following GUI (server list view) starts.
When applying only by the command, without using GUI, it is not
necessary to perform this operation.
6.4.4 Registering Storage server and SP server
The Storage management server registers the Storage server to be
managed. When the Storage server is operated as a Storage
management server does not need to add a server.
Select [Addition of server] from the [Operation] menu. The
following window appears.
52
For storage server to be added, specify a server name, IP address,
and port number required for communications. The port number is
specified as the "communications service port number", when Agent
of Softek AdvancedCopy Manager was installed.
In cluster operation, specify the logical IP address of the Storage
server as IP address. And specify the port number registered at the
time of the cluster setup of Storage server transaction.
The [OK] button is pushed after inputting the above item, and
additional processing of a Storage server is carried out.
In addition, this processing can be carried out also by the server
information addition command (stgxfwcmaddsrv).
When the SP server is registered, the Softek AdvancedCopy Manager
server list view appears, as shown below
The Storage management server need not be registered because it is
registered during repository setup.
6.4.5 Fetching device information on a storage server
Before the backup management can be performed, device information
on a storage server must be temporarily stored to the repository.
To acquire information on a device on the storage manager server,
the [Operation] menu, select [Acquisition and reflection of
Information on all devices]. The following window will be
displayed. Information about the hardware of the SP server need not
be acquired because the SP server is not managed by AdvancedCopy
Manager.
53
Confirm the server for which you want to fetch device information,
and then click the [OK] button.
After device information is fetched from each server, the following
dialog will be displayed.
The uppermost list box is displayed when a new device is detected.
Move the entries for devices to be managed into the left box. The
second list box displays currently managed devices that cannot be
detected at this time. When you want to exclude a device from
management, move the device entry into the right-hand box. The
lowermost list box displays devices for which information has been
updated (those, for example, for which the mount point name has
been changed).
After performing the above operation, click the OK button to
reflect the configuration information. For an explanation on the
Softek AdvancedCopy Manager device name, see Chapter 1.5, "Managing
a Device on Softek AdvancedCopy Manager", in the Softek
AdvancedCopy Manager Operator's Guide (Windows version).
The [OK] button is pushed after inputting the above item, and
additional processing of a Storage server is carried out.
In addition, this processing can be carried out also by the device
information collection/reflection command (stgxfwcmsetdev).
54
It takes the time proportional to the total of the device defined
in the selected Storage server for this operation. Please execute
CPU load and the I/O load low when there are a lot of numbers of
devices.
It takes about 0.5 seconds a device (partition) as a standard with
there no load, and refer, please.
6.4.6 Displaying the backup management window
When [Backup Management] is selected from the [File] menu of the
server list view, the backup management server list view
appears.
6.4.7 Setting the environment for a backup operation server
Set the environment for each storage server. When [Set Storage
Server Configuration Information] is selected from the [Operation]
menu while the storage server is selected on the backup management
window, the following setting window appears.
If the target Storage server is Solaris and the SymfoWARE database
exists in the Storage server, a recovery control file output place
directory and a work directory are inputted. When a SymfoWARE
database does not exist in a Storage server, or when a Storage
server is WindowsNT/2000, HP-UX or Linux, this input item cannot
serve as a half-tone display, and cannot be inputted.
After completing the input of necessary items, click the [OK]
button.
55
You need to make this environment setting also on the storage
management server if it serves also as a storage server. This step
is not required if the environment setting has already been made on
the storage servers.
You can also make this environment setting also using the storage
server configuration information setting command.
6.4.8 Setting the operation type for a device
Before performing backup, set the operation type of the device as
follows: · Define each volume to be backed up as a transaction
volume. · Define each backup destination volume as a backup
volume.
+Defining the transaction volume
Set an operation type on the server list view. On the server list
view, select a storage server and select the [Operation] menu and
then [Set Device Information]. The following setup window will be
displayed.
A volume displayed in "Other volume" field has no specified device
operation type. Set a device operation type as follows: · Setting
as a "transaction volume which performs SP series employment" After
selecting a target volume, click the [<] button on the
"Transaction volume(SP)" side. The target volume will be moved to
the "Transaction volume(SP)" field.
You can make this setting also using the device information setting
command (swstdevinfoset).
56
Because the device to be backed up must be managed by a model of
the SP series, system design and setup must have been performed
with respect to the SP series. See the Storage Management Processor
Administrator's Guide and Storage Management Processor Installation
Guide for details on the method of design and setup with respect to
the SP series.
Please do not register the slice which defined the whole volume as
operating volume.
When the slice composition of the volume set up as operating volume
etc. is changed, since it once deletes from registration of
transaction volume and a Storage server subordinate's device
information is taken in again, it is necessary to reregister by the
device information setting command.
The setting status of the device to be backed up can be referenced
with the device usage status display command.
+Defining the backup volume
For backup/restore in linkage with a model of the SP series, the
backup volume specified as the backup destination is managed by the
SP series model and system design and setup of the backup volume is
to be performed via the SP series GUI. See the Direct Backup User's
Guide for details on the SP series GUI.
6.4.9 Setting backup policies
Set the backup policy for the transaction volume under control of
the SP series model by using the SP series GUI.
See the Direct Backup User's Guide for details on the SP series
GUI.
Because the backup policy for the transaction volume controlled by
the SP series model is set by the SP series model, the following
commands cannot be executed for the transaction volume operated by
the SP series model:
· Backup policy setting command · Backup policy display command ·
Backup policy deletion command
6.4.10 Customizing preprocessing and postprocessing scripts
In the case of one of the two operations explained below, the
backup preprocessing and postprocessing scripts need to be
customized. · When, because of an operational reason, you want to
avoid unmount/mount processing for a transaction
volume where a file system is constructed · When you want to add
special preprocessing and postprocessing to the preprocessing and
postprocessing
scripts Refer to Appendix A, "Preprocessing and Postprocessing of
Backup and Restoration," for details on the customization.
6.5 Operation
This chapter describes how to perform backup with models of the SP
series.
Before performing backup, set up the environment needed for backup,
as described in Chapter 6.4 "Preparations".
The same operations as performed by the commands used for backup
can also be performed via the SP series GUI. See the Direct Backup
User's Guide for details on the SP series GUI.
57
6.5.1 Executing backup
Perform backup in linkage with models of the SP series with the
backup execution command.
Because the SP series manages disks for backup in linkage with the
SP series, confirm the backup status by using the SP series GUI.
See the Direct Backup User's Guide for details on the SP series
GUI.
+Snap shot backup
To perform snap shot backup, use the backup execution
command.
+Synchronous high-speed backup
Perform synchronous high-speed backup as described below: 1. Start
backup synchronous processing by executing the backup synchronous
processing start command. To
cancel backup synchronous processing, use the backup synchronous
processing cancel command. 2. It checks that the backup volume
under backup synchronous processing is in an equivalent
nature
maintenance state. It carries out by the situation check of backup,
and GUI of SP series. 3. Execute the backup execution
command.
6.5.2 Executing restore
Perform restore in linkage with models of the SP series by using
the restore execution command. To stop restore operations, and to
terminate restore operations that cannot be terminated even if an
error occurs, use the GUI of the SP series.
For information about the GUI of the SP series, refer to the Direct
Backup User's Guide.
Contents of a transaction volume cannot be used if a restore
operation for the volume has been canceled.
In linkage with models of the SP series, the SP series models
manage the disks for restore. Therefore, confirm the restore status
by using the SP series GUI. See the Direct Backup User's Guide for
details on the SP series GUI.
6.5.3 Managing backup histories
In linkage with models of the SP series, the SP series models
manage the history of backups.
Therefore, the backup history cannot be displayed or deleted using
Softek AdvancedCopy Manager.
Use the SP series GUI to display or delete the backup history. See
the Direct Backup User's Guide for details on the SP series
GUI.
6.6 Stopping Backup
To stop the backup, stop the service on the storage server. In
general, the service stops when the system stops.
It is possible to also make it stop individually to stop a demon by
a certain reason. For more Details, see Chapter 2 "Starting and
Stopping Daemons".
· When the service stops, all functions of AdvancedCopy Manager
running on the Storage server stop. · Before stopping the service
or daemon running on the Storage management server, confirm that
the
operations on all managed Storage servers have stopped.
6.7 Steps for Increases/Decreases in the Number of GR C abinets to
Be Managed
In Softek AdvancedCopy Manager, information about GR cabinets
managed by devices of the SP series is stored in a
58
repository. When adding GR cabinets to or removing GR cabinets from
those managed by devices of the SP series, these changes must be
reflected in the repository.
6.7.1 Reflecting changes
After starting the Web GUI of Softek AdvancedCopy Manager, refer to
Chapter 1.2.6.5, "Changing GR cabinet management information of the
SP series," in the Solaris OE version Softek AdvancedCopy Manager
User's Guide, to perform the operation to reflect changes.

Chapter 7 Replication Operation
This chapter explains Softek AdvancedCopy Manager replication in a
Solaris OE system. Softek AdvancedCopy Manager uses a slice as the
replication unit. In this manual, the term "volume" is used instead
of "slice."
