NetBackup OST Guide

Introduction

I This guide is for ETERNUS CS800 S3 2.1.1 Software.

V CAUTION!If you have previously used Active Directory (CIFS share) to perform authentication between an OST Plug-in and a ETERNUS CS800 S3 running 1.4.x or earlier, note that this has changed. The new method of OST Plug-in authentication between OST Plug-in 2.3 and later and ETERNUS CS800 S3 2.x and later DOES NOT USE Active Directory authentication. Instead, you must add new OST user credentials on the ETERNUS CS800 S3 and the media server. For instructions, see "Configuring OST Authentication" on page 7.

Symantec NetBackup OST (Open Storage) allows NetBackup to seamlessly integrate with a ETERNUS CS800 S3 disk backup system. Once installed and configured, NetBackup can manage the backups through the ETERNUS CS800 S3 and take advantage of the system’s capabilities such as data deduplication and replication.

Installing and configuring the ETERNUS CS800 S3 and NetBackup OST for operation consists of the following major steps. See the following sections for detailed instructions for completing each step:

1. Installing the OST Plug-in

2. Configuring the ETERNUS CS800 S3

3. Configuring Symantec NetBackup (Media Server)

4. Registering the Storage Server with NetBackup

5. Configuring Disk Pools and Storage Units in NetBackup

6. Initiating an OST Optimized Duplication

7. Configuring OST Path to Tape

8. Configuring ETERNUS CS800 S3 Accent

Installing the OST Plug-in NetBackup OST Guide

6 U41852-J-Z125-2-76

Installing the OST Plug-in

I For Replication (Optimized Duplication): the OST Client Plug-in must be installed on the media server configured with NetBackup 6.5.3 or later, or NetBackup 7.x.

I For OST Path To Tape (Direct To Tape) - NetBackup 6.5.4 or later, or NetBackup 7.x.

The OST Client Plug-in is provided as follows:

● On a data medium shipped together with the ETERNUS CS800 S3 system. A README file is included which contains detailed instructions about the installation.

● At the Fujitsu Technology Solutions support pages under:

http://support.ts.fujitsu.com/com/support/index.html

The right OST plug-in variant depends on the operating system of your Media Server.

To download the correct version of the OST Plug-in from the support pages:

1. On the system remote management console, navigate to the Configuration > OST > OST Client Plug-In page.

2. Click Client Plug-In Download.

3. Select Driver & Downloads. In the next window fill in the following values in the section Select Product.

1. Storage solutions

2. ETERNUS CS/CentricStor

3. ETERNUS CS800

You will get a list of supported operating systems. Select the desired one.

Make sure to download the correct OST Plug-in for your version of NetBackup (6.5.x or 7.x) and for the operating system installed on the NetBackup media server.

In the OST Plug-in zip-file you will find a README file, which contains the installation procedure for the OST Plug-in. This procedure is different for each NetBackup media server operating system platform. Follow the instructions to install the OST Plug-in on the NetBackup media server.

I When multiple hosts are using a single system, you can distribute the load by dividing the hosts into groups. For more information, see the section “Performance Tuning” in the README file.

I By default, the OST Plug-in for Windows is installed in theC:\Program Files\Symantec\NetBackup\ directory.

NetBackup OST Guide Configuring the ETERNUS CS800 S3

U41852-J-Z125-2-76 7

Configuring the ETERNUS CS800 S3

You must configure storage servers and logical storage units on the ETERNUS CS800 S3 remote management console before you configure NetBackup. See the following sections to configure the ETERNUS CS800 S3 for OST.

Configuring the ETERNUS CS800 S3 consists of the following major steps. See the following subsections for detailed instructions for completing each step:

● Configuring OST Authentication

● Configuring Storage Servers

● Configuring Logical Storage Units

I You can also use the OST Wizard to configure the ETERNUS CS800 S3 for OST. Refer to the User’s Guide for ETERNUS CS800 S3.

Configuring OST Authentication

To authenticate the OST storage servers on a media server, you must create OST user credentials.

V CAUTION!If you have upgraded to ETERNUS CS800 S3 2.1.1 Software from a version released prior to 2.0, you must add new OST credentials to the ETERNUS CS800 S3 to continue using OST. Shut down the NetBackup services. Then perform the procedure below, making sure to use the same username and password that were used to register the existing OST devices. Finally, start the NetBackup services.

To create OST user credentials:

1. Log on to the ETERNUS CS800 S3 remote management console.

2. Navigate to the Configuration > OST > Manage Users page (see Figure 1).

Configuring the ETERNUS CS800 S3 NetBackup OST Guide

Registering the Storage Server with NetBackup

Discovering Logical Storage Units

After the OST Plug-in is installed and configured on the NetBackup media server, you must register the storage servers with NetBackup by defining them on the media server. You must complete this process on every media server that will access the storage servers on the ETERNUS CS800 S3. You can configure multiple media servers to use the same storage servers as long as the OST Plug-in is installed on each media server. To register a storage server, first define it using the nbdevconfig command, and then provide credentials using the tpconfig command.

I For NetBackup 7.x, you can perform this process using the Storage Server Configuration Wizard instead of the CLI commands (see "Using the Storage Server Configuration Wizard" on page 23).

I The storage server argument passed to the nbdevconfig command should be in the form of <name_IP>, where the name is the name of storage server to be registered and IP is the IP address of the ETERNUS CS800 S3. If the ETERNUS CS800 S3 is configured with multiple network interfaces (see the User’s Guide for ETERNUS CS800 S3 system) the IP will be the network interface used for data. This is also applicable when registering storage servers on a Windows platform.

I If the IP address of the ETERNUS CS800 S3 or media server changes at any time after registering the storage servers (for example, due to switch changes), you must delete the existing storage servers and disk pools on the media server, and then register the storage servers again using the procedures below. You must take these actions on all media servers that access the storage servers.

Registering the Storage Server on Windows Platforms via CLI

I The procedures in this section assume NetBackup is installed in the default location on the C: drive. If you installed Netbackup in a different drive or location, modify the commands with the correct path.

I For complete usage information about these commands, refer to NetBackup Commands for Windows.

To register the storage server on a Windows NetBackup media server platform, perform the following steps:

Registering the Storage Server with NetBackup NetBackup OST Guide

20 U41852-J-Z125-2-76

1. Add the storage server to NetBackup:

C:\Program Files\Veritas\NetBackup\bin\admincmd\nbdevconfig -creatests -storage_server <storage_server_name_ip> -stype FTS -media_server <media_servername> -st 9

Example: Add a storage server by name nbustorageserver at IP address 192.168.1.100 and a media server by name nbumedia.

C:\Program Files\Veritas\NetBackup\bin\admincmd\nbdevconfig -creatests -storage_server nbustorageserver_192.168.1.100 -stype FTS -media_server nbumedia -st 9

I When specifying the -storage_server variable (passed to the nbdevconfig command), you must include both the name of the storage server (defined in the ETERNUS CS800 S3 storage server configuration) and the IP address of the ETERNUS CS800 S3 separated by an underscore. For example: nbustorageserver_192.168.1.100

I If the ETERNUS CS800 S3 is configured with multiple network interfaces (see the User’s Guide for your ETERNUS CS800 S3 system), the IP address of the interface enabled for data should be used to register the storage server

I A message from the prompt indicates that the storage server was added successfully. Otherwise, an error message is displayed.

2. Specify the credentials of the storage server:

C:\Program Files\Veritas\Volmgr\bin\tpconfig -add -storage_server <storageserver_ip> -stype FTS -sts_user_id <username> -password <password>

Example: Add credentials for storage server nbustorageserver.

Verifying the LSU Discovery

After you have registered the storage server, verify the discovery of LSUs by performing the following step:

1. From the command line on the master server, type:

<install path>\netbackup\bin\admincmd\nbdevconfig –previewdv -stype FTS –storage_servers <storageserver_ip>

Example: Verify LSU discovery for storage server nbustorageserver.

C:\Program Files\Veritas\NetBackup\bin\admincmd\nbdevconfig -previewdv -stype FTS -storage_servers nbustorageserver_192.168.1.100

I When specifying the -storage_server variable, you must include both the name of the storage server (defined in the ETERNUS CS800 S3 storage server configuration) and the IP address of the ETERNUS CS800 S3 separated by an underscore. Storage server names are case sensitive on all platforms including Windows. For example: nbustorageserver_192.168.1.100

This will show if the storage server has been discovered by NetBackup and if the password is correct.

Registering the Storage Server on Unix/Linux Platforms

I For complete usage information about these commands, refer to NetBackup Commands for UNIX and Linux.

To register the storage server on Solaris or Linux NetBackup media server platforms:

1. Add the storage server to NetBackup by executing the following command on the NetBackup media server as root:

/usr/openv/netbackup/bin/admincmd/nbdevconfig -creatests -storage_server <storageserver_ip> -stype FTS -media_server <media_servername> -st 9

Example: adding a storage server by name nbustorageserver and a media server by name nbumedia.

/usr/openv/netbackup/bin/admincmd/nbdevconfig -creatests -storage_server nbustorageserver_192.168.1.100 -stype FTS -media_server nbumedia -st 9

I When specifying the -storage_server variable (passed to the nbdevconfig command), you must include both the name of the storage server (defined in the storage server configuration) and the IP address of the ETERNUS CS800 S3 separated by an underscore. For example: nbustorageserver_192.168.1.100


22 U41852-J-Z125-2-76

I If the ETERNUS CS800 S3 is configured with multiple network interfaces (see the User’s Guide for your ETERNUS CS800 S3 system), the IP address of the interface enabled for data should be used to register the storage server.

I A message from the prompt indicates that the storage server was added successfully. Otherwise, an error message is displayed.

2. Specify the credentials of the storage server:

/usr/openv/volmgr/bin/tpconfig -add -storage_server <storageserver_ip> -stype FTS -sts_user_id <username> -password <password>

Example: Adding credentials for storage server nbustorageserver.

/usr/openv/volmgr/bin/tpconfig -add -storage_server nbustorageserver_192.168.1.100 -stype FTS -sts_user_id ostuser -password password


I When specifying the -storage_server variable, you must include both the name of the storage server and the IP address of the ETERNUS CS800 S3 separated by an underscore. For example:nbustorageserver_192.168.1.100

I No message displays if the credentials are added successfully. But an error message displays if the credentials are incorrect.

Verifying the LSU Discovery

After you have registered the storage server, verify the discovery of LSUs:

1. From the command line on the master server, type:

/usr/openv/netbackup/bin/admincmd/nbdevconfig –previewdv –stype FTS–storage_servers <storageserver_ip>

Example: Verify LSU discovery for storage server nbustorageserver.

/usr/openv/netbackup/bin/admincmd/nbdevconfig –previewdv –stype FTS–storage_servers nbustorageserver_192.168.1.100

I When specifying the -storage_server variable, you must include both the name of the storage server (defined in the ETERNUS CS800 S3 storage server configuration) and the IP address of the ETERNUS CS800 S3 separated by an underscore. For example: nbustorageserver_192.168.1.100

This will show if the LSU has been discovered by NetBackup and if the password is correct.

Initiating an OST Backup

See the NetBackup System Administrator’s Guide for information on creating a backup policy to backup data to an OST disk pool.

Performing Synthetic Full Backups

A synthetic backup is a backup in which content from a series of backups, starting with a full backup and followed by incremental backups, is combined into a new backup-typically a full backup.

For a synthetic backup to be successful, all the backups from the series must be intact and internally consistent. Intact means that each backup created still exists and no backup in the series has been expired. Internally consistent means that the individual backup catalogs are all consistent. The catalogs can become inconsistent for a variety of reasons, for example, by running two backups for a client and policy concurrently. (A scenario when this example can occur is if a manual incremental backup is performed while a scheduled incre-mental backup job is in progress.)

During a synthetic backup, the backup application first queries and analyzes the backups for the given policy and client and then attempts to use their catalog data to combine the content into a new logical backup. If a backup is missing, or if file metadata is inconsistent, the synthetic backup will fail with an error 671.

Primary causes of error 671 include the following:

● Expiration of a backup in the full/incremental series.

● Inconsistent incremental metadata due to concurrent backups in the series.

● Inconsistent incremental metadata due to utilization of Windows Archive Bit and cumulative incremental backups.

● Inconsistent incremental metadata due to, prior to NetBackup 7.1, use of dynamic selections and multistreaming.

NetBackup OST Guide Initiating an OST Backup

U41852-J-Z125-2-76 39

To configure NetBackup to store optimized synthetic full backups verify the OptimizedImage flag is set for the storage server and the disk pool. To confirm the OptimizedImage flag is set use /usr/openv/netbackup/bin/admincmd/nbdevquery -liststs -U for the storage server and /usr/openv/netbackup/bin/admincmd/nbdevquery -listdp -U for the disk pool.

To add the OptimizedImage flag to a existing server use /usr/openv/netbackup/bin/admincmd/nbdevconfig -changests -stype FTS -storage_server <storage-server-name> -setattribute OptimizedImage and to the disk pool use /usr/openv/netbackup/bin/admincmd/nbdevconfig -changedp -stype FTS -dp <disk-pool-name> -setattribute OptimizedImage.

Initiating an OST Optimized Duplication NetBackup OST Guide

40 U41852-J-Z125-2-76

Initiating an OST Optimized Duplication

The ETERNUS CS800 S3 has the capability to copy data on one system to another system (that is, the capability to perform replication). NetBackup uses this capability to initiate an optimized duplication of backup images between these appliances. The duplication operation of NetBackup triggers the duplication function in the OST disk appliance if both the source and destination volumes for the copy are OST LSUs.

OST optimized duplication reduces the workload on the NetBackup media server because the replication is performed by the ETERNUS CS800 S3. Duplication is done in the background, and it is faster because it uses data deduplication capabilities to reduce the copy bandwidth. Duplication is still initiated, managed, and controlled by the NetBackup media server while the actual data movement process is off-loaded to gain the maximum benefits from the appliance’s replication capabilities.

OST optimized duplication can be used for duplication from or to a ETERNUS CS800 S3 as a disk backup target.

I To increase the performance, it is recommended to configure the ETERNUS CS800 S3 to use the replication channel when performing optimized duplication (see "Replication Channel for OST" on page 41)

I For versions of NetBackup prior to 6.5.4, no more than two optimized duplication streams per source ETERNUS CS800 S3 to a target ETERNUS CS800 S3 are supported.

To initiate an optimized duplication with the Administration Console:

1. In the NetBackup Administration Console, expand the NetBackup Management Catalog.

2. Set up the search criteria for the image you want to duplicate.

3. Click Search Now.

4. Right-click an image you want to duplicate and select Duplicate from the shortcut menu.

I You must designate an OST storage unit as the destination for the duplication. Use the Storage Unit field in the Setup Duplication Variables dialog box.

I If the optimized duplication fails, the duplication will be attempted using the default duplication method used in versions of NetBackup prior to 6.5.4. With NetBackup 6.5.4 or 7.x, the administrator can control this failover using a configurable option. See the Symantec Technote at http://www.symantec.com/business/support/index?page=content&id=TECH6994 for more information on this option.

NetBackup OST Guide Initiating an OST Optimized Duplication

U41852-J-Z125-2-76 41

Also you can initiate an OST Optimized Duplication using the NetBackup Lifecycle Policy. To configure a NetBackup Lifecycle Policy you need two Storage Servers and the associated LSUs on two ETERNUS CS800 S3.

For more information, see the sections “Duplicating Backup Images” and "Creating a storage lifecycle policy" in the NetBackup System Administrator's Guide.

Replication Channel for OST

Replication Channel for OST allows the ETERNUS CS800 S3 to use the replication channel to perform optimized duplication. This significantly increases performance. In addition, more than two optimized duplication streams per source ETERNUS CS800 S3 are supported.

I When using Replication Channel for OST, only a single replication target can be configured on the ETERNUS CS800 S3.

V CAUTION!Replication Channel for OST requires the network interfaces used for replication on the source and target ETERNUS CS800 S3 to be on the same subnet.

To use Replication Channel for OST when performing optimized duplication:


2. On the target ETERNUS CS800 S3, perform the following steps:

a) Navigate to the Configuration > Replication > Receive page (see Figure 21).

Figure 21: Replication Receive Page

Initiating an OST Optimized Duplication NetBackup OST Guide

42 U41852-J-Z125-2-76

b) In the Source Hostname or IP Address box, enter the host name or IP address of the system that will send the replicated data to the ETERNUS CS800 S3.

c) Click Add.

3. On the source ETERNUS CS800 S3, perform the following steps:

a) Navigate to the Configuration > Replication > Send page (see Figure 22).

Figure 22: Replication Send Page

b) In the Target Hostname or IP Address box, enter the host name or IP address of the system that will receive the replicated data.

c) In the Source IP Address field, enter the IP address that is used to uniquely identify the source ETERNUS CS800 S3 to the target. This may be different than the actual network IP address of the source ETERNUS CS800 S3.If the target system is at ETERNUS CS800 S3 2.1.1 Software or higher, this field is not required. If the target system is at ETERNUS CS800 S3 2.0.1.x Software or below, then you must enter the IP address by which the target system recognizes the source system. The default value is 0.0.0.0.

d) (Optional) Leave the Use Encryption check box selected to enable encryption when sending replication data to the target system. Or clear the Use Encryption check box to disable encryption when sending replication data to the target system.If encryption is enabled, select an encryption strength (128-bit or 256-bit). Using 256-bit encryption (default) provides a stronger level of security but may have an impact on system performance in some situations.

OST Plug-in Configurable Options

The following OST Plug-in configurable options are supported:

Linux and Unix

The following Linux and Unix configurable options are supported:

1. DEBUG_LEVEL: Defines the level of logging to enable. The value of this option defines the level of log messages to output. It is set to one of the following values:

● EMERGENCY

● ALERT

● CRITICAL

● ERROR

● WARNING

● NOTICE

● INFO

● DEBUG

By default, DEBUG_LEVEL is set to ERROR.

2. OPDUP_TIMEOUT:The Optimized copy option of NetBackup uses the replication feature of the OST server. The OST server replication feature cannot replicate unless the backup image file is deduplicated.On demand deduplication of the backup image file can take an unknown amount of time. OPDUP_TIMEOUT is the time in seconds to wait for deduplication of backup image file extent of 256 MB or smaller before giving up on the replication attempt.If the file copy extent length is larger than 256 MB, then the wait time will be a propor-tional multiple of OPDUP_TIMEOUT. For example, if the extent length is X*256 MB, wait time will be X*OPDUP_TIMEOUT, where X need not be an integer. By default, OPDUP_TIMEOUT is set to 180 seconds.

I This option is available only on Linux and Unix platforms. On Windows the timeout is fixed at 180 seconds.

To change the default value of any of these options, edit the /usr/FTS/FTSPlugin.conf file and set the desired values.

U41852-J-Z125-2-76 45

Windows

The following Windows configurable options are supported:

1. LOG_LEVEL: This is similar to the DEBUG_LEVEL on Linux and Unix. It defines the level of logging to enable. The value of this option defines the level of log messages to output.

● NONE - Disables logging for the logger.

● TRACE - Enables tracing to error messages.

● DEBUG - Enables debug to error messages.

● INFO - Enables information to error messages.

● WARN - Enables warning and error messages.

● ERROR - Enables only error messages.

2. LOG_LIMIT: It defines the maximum file size (in byte) for the logger. Default size of the log file is 10MB. Increase this value if more logging has to be captured.Edit %WINDIR%\libstspiFTS*.ini to change the default values.

Configuring OST Path to Tape NetBackup OST Guide

46 U41852-J-Z125-2-76

Configuring OST Path to Tape

The OST path to tape (Direct to Tape) option allows you to copy OST LSUs to a physical tape library.

I This procedure assumes that you have physically connected the ETERNUS CS800 S3 and the target library using Fibre Channel either directly or through a Fibre Channel SAN. If you are connecting the devices using a SAN, you must perform the appropriate Fibre Channel switch zoning. You must also appropriately map the library device LUNs on the library side to correctly present them to the ETERNUS CS800 S3.

Configuring OST path to tape consists of the following major steps. See the following subsections for detailed instructions for completing each step:

● Verifying Prerequisites

● Configuring Physical Tape Libraries

● Configuring NetBackup OST for Path to Tape

Verifying Prerequisites

The following steps must be completed before setting up NetBackup OST path to tape:

● The NetBackup version running on the media server must be 6.5.4 or later, or 7.x, with all updates applied.

● The ETERNUS CS800 S3 must be installed and configured.

● Fibre Channel connectivity must be configured.

● Aliases for the NDMP host (the ETERNUS CS800 S3) must be created on the EMM server (see "Creating Aliases for the NDMP Host").

Creating Aliases for the NDMP Host

For optimal path to tape (direct copy) performance, you should create aliases for the NDMP host (the ETERNUS CS800 S3) on the Enterprise Media Manager (EMM) server.

If you create aliases for the ETERNUS CS800 S3, then data is sent directly from the ETERNUS CS800 S3 to tape during path to tape (direct copy) operations. If you do not create these aliases, data will be sent from the ETERNUS CS800 S3 to the media server, then back to the ETERNUS CS800 S3 before it is written to tape, which can cause slower performance.

NetBackup OST Guide Configuring OST Path to Tape

U41852-J-Z125-2-76 47

To create aliases for the NDMP host:

1. On the EMM server, retrieve a list of all NDMP hosts (ETERNUS CS800 S3 systems).

For Windows, run the following command:

C:\Program Files\Veritas\NetBackup\bin\admincmd\nbemmcmd -listhosts -machinetype ndmp

For Linux or Solaris, run the following command as root:

/usr/openv/netbackup/bin/admincmd/nbemmcmd -listhosts -machinetype ndmp

2. For each host (ETERNUS CS800 S3) returned in Step 1 that will be performing direct copy to tape, retrieve a list of aliases


C:\Program Files\Veritas\NetBackup\bin\admincmd\nbemmcmd -machinealias -getaliases -machinename <ndmphost> -machinetype ndmp


/usr/openv/netbackup/bin/admincmd/nbemmcmd -machinealias -getaliases -machinename <ndmphost> -machinetype ndmp

3. A host (ETERNUS CS800 S3) should have all available aliases: NetBIOS hostname, DNS hostname, and FQDN (fully qualified domain name). If the host (ETERNUS CS800 S3) does not have one or more of these aliases, you should create them. To create an alias for a host (ETERNUS CS800 S3), use the following commands.


C:\Program Files\Veritas\NetBackup\bin\nbemmcmd.exe -machinealias -machinename <ndmphost> -addalias -alias hostname.domain.gov -machinetype ndmp


/usr/openv/netbackup/bin/admincmd/nbemmcmd -machinealias -machinename <ndmphost> -addalias -alias hostname.domain.gov -machinetype ndmp

I To correct any DNS issues (or simply to be proactive), you can add the entries to the hosts file.

U41852-J-Z125-2-76 51

Running a Duplication to Tape

NetBackup uses NDMP direct copy when you duplicate a backup image. Certain conditions apply to the duplication, explained in this section.

To run a duplication, you can use any of the following methods:

● The Duplicate option in the Catalog node of the NetBackup Administration Console.

● NetBackup Vault (see the NetBackup Vault Administrator’s Guide).

● The bpduplicate command (see the NetBackup Commands Guide).

● A NetBackup Storage Life-cycle Policy.

Requirements

For NetBackup to use NDMP direct copy when you duplicate an image:

● As the destination for the duplication, you must designate an NDMP storage unit in an ETERNUS CS800 S3.

● An NDMP tape drive must be available to mount the target image. The NDMP tape drive must be a physical tape drive in a tape library.

If these two requirements are met, NDMP direct copy is enabled. NetBackup copies the image directly to the designated storage unit without using media server I/O or network bandwidth.

Initiate NDMP Direct to Tape with the Administration Console

To initiate a NDMP Direct to Tape with the Administration Console:

1. In the NetBackup Administration Console, expand NetBackup Management > Catalog.

Configuring ETERNUS CS800 S3 Accent

ETERNUS CS800 S3 Accent software accelerates backups and reduces network bandwidth requirements by distributing deduplication between the backup server and the ETERNUS CS800 S3.

To use ETERNUS CS800 S3 Accent, all of the following requirements must be met:

● Firewall port 1062 is open for IP address that is used for data transfer.

● The media server meets the following requirements:

● Operating System - Linux

● CPU - Greater than 2.2 GHz processor with at least 2 cores (4 cores recommended)

● Memory - 2 GB RAM or greater

● The OST Plug-in is installed on the media server (see "Installing the OST Plug-in" on page 6).

● Accent is enabled on the ETERNUS CS800 S3 (see "Enabling or Disabling Accent on the ETERNUS CS800 S3" on page 53). By default, Accent is disabled on the ETERNUS CS800 S3.

● Accent is enabled on the media server (see "Enabling or Disabling Accent on the ETERNUS CS800 S3" on page 53). By default, Accent is enabled on the media server when you install the OST Plug-in (see "Enabling or Disabling ETERNUS CS800 S3 Accent on the Media Server" on page 54).

When all of these requirements are met, Accent will be used for all OST transport between the media server and the ETERNUS CS800 S3. Otherwise, normal OST transport will be used. For information about the maximum number of connections when Accent is enabled, see "Maximum Number of Jobs When Using ETERNUS CS800 S3 Accent" on page 54.

I When ETERNUS CS800 S3 Accent is in use, you can monitor Accent performance information in the ETERNUS CS800 S3 remote management console, on the Status > Accent page. For more information, see the User’s Guide for your ETERNUS CS800 S3 system.

Enabling or Disabling Accent on the ETERNUS CS800 S3

By default, ETERNUS CS800 S3 Accent is disabled on the ETERNUS CS800 S3. To use Accent, you must enable it on the ETERNUS CS800 S3.

I If Accent is enabled, all media servers that are not running RedHat Linux and that are using the same ETERNUS CS800 S3 must have the latest OST plug-in installed.

To enable or disable Accent on the ETERNUS CS800 S3:

1. Access the ETERNUS CS800 S3 remote management console.

2. Navigate to the Configuration > OST > Accent page (see Figure 26).

Figure 26: Accent Page

3. To enable ETERNUS CS800 S3 Accent, select the Enable Inline Dedupe with Accent check box.Or to disable ETERNUS CS800 S3 Accent, clear the Enable Inline Dedupe with Accent check box.

4. (Optional) Select the Use Encryption check box selected to enable encryption when sending OST data from the media server to the ETERNUS CS800 S3.Or clear the Use Encryption check box to disable encryption when sending OST data from the media server to the ETERNUS CS800 S3.If encryption is enabled, select an encryption strength (128-bit or 256-bit). Using 256-bit encryption (default) provides a stronger level of security but may have an impact on system performance in some situations.

5. Click Apply.

Enabling or Disabling ETERNUS CS800 S3 Accent on the Media Server

By default, ETERNUS CS800 S3 Accent is enabled on the RedHat Linux Netbackup media server when you install the OST Plug-in.

Because use of Accent can be enabled individually on each ETERNUS CS800 S3, there is typically no need to disable Accent on the media server. However, you might want to disable Accent on an individual media server if that media server is equipped with a slow CPU or if the type of data being backed up is not easily deduplicated. Note that you may mix Accent-enabled and Accent-disabled media servers with a single ETERNUS CS800 S3.

To enable or disable Accent on the media server:

1. Open the following configuration file for editing:

/usr/FTS/FTSPlugin.conf

2. In the configuration file, locate the IO_PATH variable.

● To enable Accent, set the value of the IO_PATH variable to 4. For example:

IO_PATH=4

● To disable Accent and revert to using traditional OST transport, set the value of the IO_PATH variable to 1. For example:

IO_PATH=1

3. Save and close the configuration file.

Maximum Number of Jobs When Using ETERNUS CS800 S3 Accent

When Accent is enabled on the ETERNUS CS800 S3, a maximum of 20 (for ETERNUS CS800 S3 Entry a maximum of 10) concurrent jobs can be run against the ETERNUS CS800 S3. Any of the following job types count toward the maximum number of jobs:

● Backups

● Restores

● Optimized duplications

If the connection limit is reached, the following message is logged in the OST Plug-in log:

Jul 19 04:55:27 loaner4 Blockpool[20575]: S: [108753] (Select Server) VServer "hybrid-dedupe-no-encrypt" limit reached (limit 20).

In addition, NetBackup progress displays the following message:

07/19/2011 13:53:36 - Critical bpdm (pid=12515) image open failed: error 2060020: storage server connection limit exceeded

When the connection limit is reached on the ETERNUS CS800 S3, The OST plug-in retries the connection for 300 seconds by default. If the connection cannot be established after 300 seconds, the connection times out and an error is returned.

The default connection timeout is 300 seconds. To change the timeout value, edit the following setting in the /usr/FTS/FTSPlugin.conf file.

DATA_CONNECTION_BUSY_TIMEOUT
