Symantec NetBackupThe HP OST plug-in works with the following NetBackup versions:

v7.5

v7.6

NOTE: Be sure to observe the following notes:

While installing NetBackup, be sure to take note of and appropriately resolve all warningsand errors encountered during pre-install checks. Failure to do so may impact backup operationslater.

It is recommended that you install NetBackup first, and then install the HP OST plug-in.

3 Installing the HP OpenStorage (OST) plug-inThis section provides information on:

Downloading the OpenStorage plug-in (page 6)

Installing/Updating the OpenStorage plug-in with NBU (page 6)

Uninstalling the OST plug-in (page 8)

Downloading the OpenStorage plug-inDownload the HP OST plug-in installer zip or tar file from www.software.hp.com/kiosk ontoNetBackup (NBU) media servers. (Refer to your sales contact for user ID and password information.)

Installing/Updating the OpenStorage plug-in with NBUBefore you begin the installation, make sure that Symantec NetBackup is installed. See theNetBackup Installation Guide for its installation instructions.

IMPORTANT: If you are installing OST v3.0 on AIX, ensure that you use the appropriate .rpmfile before completing installation instructions.

For AIX v7.1: gcc-c++-4.8.1-1.aix7.1.ppc.rpm

For AIX v6.1: gcc-c++-4.8.1-1.aix6.1.ppc.rpmYou must install the above AIX packages before proceeding.

NOTE: Before completing AIX installations, observe the following:

On AIX media servers, where IPv6 is not configured, you must configure the /etc/netsvc.conf file as hosts=local4,bind4. Failure to do so causes NetBackup to markdisk volumes as down due to latencies introduced by AIX resolving storage server addresses.

For AIX installations, typically, the page size setting is set to 512 MB. This setting must bechange to 4 GB to allow for the seamless operation of NetBackup installations. Be sure tochange this setting before completing the AIX installation process. Failure to do so causes slowor unresponsive operations on the AIX server.

On AIX media servers, when the system reports the disk volume status to the master server,delays may occur, and the system may then mark disk volumes as being down and may alsomark media servers as being not active. In this case, backup operations fail, and the NetBackupAdministration Console may also show poor response and, in some cases, no response. Towork around this issue, execute the following steps on each of the NetBackup Media servers,and then restart NetBackup services:# touch /usr/openv/netbackup/db/config/DPS_PROXYNOEXPIRE# echo "3600" > /usr/openv/netbackup/db/config/DPS_PROXYDEFAULTSENDTMO# echo "3600" > /usr/openv/netbackup/db/config/DPS_PROXYDEFAULTRECVTMO

6 Installing the HP OpenStorage (OST) plug-in

5 Setting up un-targeted Auto Image Replication (AIR) withNetBackup (NBU)

Topics included in this section are as follows:

About un-targeted AIR (page 12)

AIR Prerequisites (page 13)

Setting up AIR (page 14)

About un-targeted AIRThe Auto Image Replication (AIR) feature of NetBackup (NBU) addresses the site-to-site replicationchallenge by allowing storage lifecycle policies to duplicate selected images between NetBackupMaster Domains. The primary purpose of Auto Image Replication is to create off-site copies ofmission critical backups to protect against site loss.Figure 1 (page 13) provides an overview of how AIR needs to be set up with HP OST v2.1 orlater. It displays some of the prerequisites that need to be satisfied before setting up AIR. Pleasesee the AIR Prerequisites (page 13) for complete information.

NOTE:

Only un-targeted AIR operations are supported by HP OST v2.1 or later on NBU v7.6.

Un-targeted AIR operations are not supported with HP OST v3.0 on AIX and HP-UX operatingsystems.

8. Storage server 27. Storage server 1

10. Object store 29. Object store 1

11. Object store 3

AIR PrerequisitesBefore setting up AIR, makes sure that:

NBU source and target master domains are accessible over the network to each other.

Both source and target stores use the same client identifier for the AIR operation (in case clientaccess permission checking is enabled).

NBU does not have any provisions for setting up replication topologies for third-party storagevendors. To set up replication topologies for the HP StoreOnce Backup System, storageadministrators must use the tpman tool that shipped with the HP OST plug-in.

The source and target master domain, AIR SLP names and data classification, are exactly thesame.

The date and time on source and target NBU domains should be set to their respective currenttime. NBU delays import of images at the target master if the time stamp on the replicatedimage is in the future.

AIR Prerequisites 13

Setting up AIRTo set up AIR:1. Create stores on the source and target HP StoreOnce Backup System. (Refer to HP StoreOnce

Back System documentation at http://h20565.www2.hp.com/portal/site/hpsc/public/psi/manualsResults/?lang=en&cc=us&sp4ts.oid=5196525http://h20565.www2.hp.com/portal/site/hpsc/public/psi/manualsResults/?lang=en&cc=us&sp4ts.oid=5196525 for moreinformation.)

2. Set up topology:a. HP provides a CLI tool (tpman) to storage administrators for replication topology setup.

The tool is installed automatically after the HP OST v3.0 plug-in is installed. The tool islocated at:

For Windows: %SystemRoot%\Program Files\Hewlett-Packard\OpenStorage\3.0\bin

For Linux: /usr/openv/hp/ost/3.0/bin For HP-UX: /usr/openv/hp/ost/3.0/bin For AIX: /usr/openv/hp/ost/3.0/bin

b. Use the tpman tool to setup replication topology. HP OST v3.0 supports replicationtopology setup between stores. Topology can scale in an m:n fashion.

Tpman usage:

For Windows: tpman.exe -add -source -target [-clientid ]

tpman.exe -remove -source -target [-clientid ]

tpman.exe -showtopology -store [-clientid ]c. For all other platforms (non-Windows platforms), use tpman as follows:

tpman -add -source -target [-clientid]

tpman -remove -source -target [-clientid]

tpman -showtopology -store [-clientid ]d. Run the add command as shown below. In the example below, Catalyst Store,

Air_Demo_62_1, of storage server 10.11.3.62 replicates to Catalyst Store,Air_Demo_64_1, of storage server 10.11.3.64.

Figure 2 Running the add command example

NOTE: Source Catalyst Stores and target Catalyst Stores should have same clientidentifiers.

3. Create storage units and disk pools out of these replication-enabled Catalyst Stores, for usewith AIR, and then restart NBU services.


NOTE: You can change the topology of a Catalyst Store even after it has been added as adisk pool. If doing so, always remember to refresh the disk pool as shown below.

Figure 3 Creating storage units and disk pools from replication-enabled Catalyst Stores

4. Create a Storage Lifecycle Policy (SLP) on the source master server as shown below.

Figure 4 Creating a Storage Lifecycle Policy on the source master server

Setting up AIR 15

5. Create a policy that uses this SLP.

NOTE: The policy should start to backup and replicate selected backup sets to the replicaas set up when using tpman.

Figure 5 Creating a policy from the Storage Lifecycle Policy

6. Create an SLP on the target master server.

NOTE: Source SLP and target SLP names and their data classification must be exactly thesame.


Figure 6 Creating a Storage Lifecycle Policy on the target master server

7. After the import operation for SLP is successfully created, note that the target starts polling forimage replication events and starts to automatically import these images into the target domain.

NOTE: With default settings in place, it may take NBU up to 30 minutes until the imagebeing imported is seen in the catalog of the other NBU domain. You can modify this behaviorby changing configuration parameters at host propertiesPropertiesSLP Parameters in theNetBackup Administration Console. Please refer to the NetBackup 7.x Administrator's Guidefor more details.

18 Setting up other NetBackup (NBU) functions

7 Setting up NetBackup with Federated Catalyst StoresHP OpenStorage (OST) v3.0 or later supports Federated Catalyst Stores which enable HP StoreOnceCatalyst Stores to span across multiple service sets; thereby, enabling Catalyst Store capacitieslarger than the physical capacity of an HP StoreOnce appliance. Federated Catalyst Stores alsosimplify the management of large backup targets. The use of a HP StoreOnce federated CatalystStore is transparent to NetBackup (NBU). The backup user must connect to one or any storageserver (that is part of the Federated Catalyst Store), and configure NBU. For details on creatingand managing federated Catalyst Stores, refer to the HP StoreOnce Backup System User Guide.

NOTE: OST v3.0 is qualified with Federated StoreOnce Catalyst stores. However, FederatedStoreOnce Catalyst stores is a controlled release feature and can only be enabled on request toHP.

8 Setting up NetBackup with Granular Recovery Technology(GRT)

HP OpenStorage (OST) v3.0 supports Symantecs NetBackup (NBU) Granular Recovery Technology(GRT) feature, a feature that enables select items from database backups to be restored on clients.GRT has been tested with Microsoft Exchange Server, Active Directory(AD) Server, and MicrosoftSharePoint solutions. For details on GRT setup information, refer to the appropriate Symantec andMicrosoft documentation.While setting up NBU backup policies for GRT, be sure to check Enable Granular Recovery forgranular restores later.
