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.

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.
