AIX: Applying a fix pack to Tivoli Storage Manager V7 in a clustered environment for AIX

Tivoli® Storage Manager maintenance updates, which are also referred to as fix packs, bring your server up to the current maintenance level. It is possible to apply a fix pack onto a clustered environment for AIX®.

Before you begin

To install a fix pack or interim fix to the server, install the server at the level on which you want to run it. You do not have to start the server installation at the base release level. For example, if you currently have Version 6.3.4.2 installed, you can go directly to the latest fix pack for V7.1. You do not have to start with the V7.1.0 installation if a maintenance update is available.

Procedure

Back up the database. The preferred method is to use a snapshot backup. A snapshot backup is a full database backup that does not interrupt any scheduled database backups. For example, issue the following command:
```
backup db type=dbsnapshot devclass=tapeclass
```
If you must revert the server to the previous level, you must have the database backup and the configuration files to restore the server to the previous level.
Back up the device configuration information. Issue the following command:
```
backup devconfig filenames=file_name
```
where file_name specifies the name of the file in which to store device configuration information.
Back up the volume history information. Issue the following command:
```
backup volhistory filenames=file_name
```
where file_name specifies the name of the file in which to store the volume history information.
Save a copy of the server options file, typically named dsmserv.opt. The file is in the server instance directory.
If you are using application level monitoring of the Tivoli Storage Manager server, from the primary node, suspend monitoring of the dsmserv application resource. To suspend monitoring, use the smitty IBM® PowerHA® menu.
Stop the Tivoli Storage Manager server.
Verify that the database manager is not running.
Mount all shared resources on the primary node. Verify that no other nodes have write access to these resources during the fix pack installation. If your environment includes multiple instances of Tivoli Storage Manager, shared resources for all instances must be accessible to the primary node during the fix pack installation.
Install the Tivoli Storage Manager server on the primary node.
Start the Tivoli Storage Manager server.
Halt the Tivoli Storage Manager server. Go to the secondary node.
On the secondary node, install the Tivoli Storage Manager server.
