New client configuration in cluster to backup

Created: 16 Oct 2013 • Updated: 04 Dec 2013 | 1 comment
This issue has been solved. See solution.

Recently there was a migration in our environment in which one of the client machine in cluster configuration was migrated to a new client machine. 

The migrated one was the passive node in the cluster and all the DB instances are successfully running in the active node of the cluster. 

Eg: 

First physical server name 1        : Server001  

Second physical server name 2    : Server002

New Client that was added           : Server003

Cluster server name                     : Clustername001

DB instances are successfully running in Server001. 

We have configured two policies to backup the SAP DB

Policies:

Online backup:

Poilicy name: Server001_Server002

Backup Selection : /oracle/<DB name>/scripts/backup/sap_online  

Client Selection : Clustername001 (Cluster name)

Offline backup:

Policy name: Server001_Server002_OFF

Backup Selection : /oracle/<DB name>/scripts/backup/sap_offline

Client Selection : Clustername001 (Cluster name)

I woud like to know what are the prechecks to be done on the new client machine in the cluster that was configured.

Apart from checking the related NBU services and the ports, from backup perspective what are the other changes to be made on the backup side?

Let me know if any other information is required.

Are the backup scripts located on a shared drive or local path?

If local path, you need to ensure that backup scripts exist on all nodes.

Check that NBU is installed with same NBU version and patch as other nodes.

Link NBU plugin to SAP. Extract from NBU for SAP Admin Guide:

Link backint from the NetBackup install directory to the SAP tools directory.
ln -s /usr/openv/netbackup/bin/backint /usr/sap/CER/SYS/exe/run/backint
 
(See manual for different examples)
