Failover of Application Other Than Data Protector

As the Data Protector cluster Cell Manager is a storage application within a cluster environment, it has to be aware of other applications that might be running within the cluster. If they are running on a node other than Data Protector and if some application fails over to the node where Data Protector is running, this will result in a high load on this node. The node that previously managed only backup operations has now to handle critical application requests as well. Data Protector allows you to define what should happen in such a situation so that the critical application data is protected and the load is balanced again. You can:

• Abort all running backup sessions

• Abort specific running backup sessions

• Inhibit the Data Protector cluster Cell Manager for a specific time frame

 

Aborting All Running Sessions If the backup is less important than

 

the application, Data Protector can automatically abort all running

 

sessions to balance the load after failover of the application.

 

To define this option use the omniclus command. This command is used

 

as part of a script that is run when a failover of the application occurs.

 

You need to create this script in advance and define it as a new resource

 

type in the application group.

 

To create the script that will abort all running sessions at failover of the

 

application other than Data Protector, perform the following steps:

 

1. In the <Data_Protector_home>\bin directory create a batch file

 

with the following command line:

 

omniclus.exe -clus<Data Protector_virtual_server>

 

-session * -abortsess

 

 

NOTE

The * wild card represents all sessions. It can be replaced with the name

 

of a specific backup specification in order to abort only this specific

 

backup session.

 

2. Open the Windows Cluster Administrator and add a new resource to

 

 

the application group. For Resource type select Generic

 

Application. For Possible owners select the node on which this
