Tivoli Storage Manager for Windows Backup-Archive Clients Installation and User's Guide

Step 4: Creating A Generic Service Resource For Failover

To add a Generic Service resource to each cluster group managed by the backup-archive client use the Cluster Administrator, as follows:

  1. Select the group-a folder under the MSCS-Cluster\Groups folder and select File --> New --> Resource from the dropdown menu.
  2. In the New Resource dialog, enter the following information:
  3. In the Possible Owner dialog, ensure that all cluster nodes appear as possible owners. Press Enter.
  4. In the Dependencies dialog add all physical disk resources as Resource Dependencies. Press Enter.
  5. In the Generic Service Parameters dialog, enter the service name you specified with the dsmcutil command, in the Service Name field. Leave the Startup Parameters field blank. Press Enter.
  6. In the Registry Replication dialog, add the registry key corresponding to the Tivoli Storage Manager node name and server name. The format for this key is:
    SOFTWARE\IBM\ADSM\CurrentVersion\BackupClient\Nodes\nodename\servername
    

    where nodename is the name of your Tivoli Storage Manager node, and servername is the name of the Tivoli Storage Manager server that the node connects to. For example, if the node name is mscs-cluster-group-a and the Tivoli Storage Manager server name is mytsmserver, then you should enter the following registry key in the Registry Replication dialog:

    SOFTWARE\IBM\ADSM\CurrentVersion\BackupClient\Nodes\mscs-cluster-group-a\mytsmserver
    
    Note:
    This entry should match an existing key in the registry.
  7. Select the new resource from the Cluster Administrator utility, and click File and then Bring Online from the dropdown menu.

Repeat this procedure for each cluster group managed by Tivoli Storage Manager.

The new scheduler service is now associated with the cluster group. If the group is moved (failed) to the other nodes in the cluster, the service should correctly fail over between the cluster nodes and notify both cluster nodes of automatic password changes.

Note:
If you manually change the Tivoli Storage Manager password, you will need to stop the scheduler service, regenerate the password, and restart the scheduler service.The password can be generated by running the command:
dsmc query session -optfile="q:\tsm\dsm.opt"
