option statement. For example, if you want to add the R:\ drive, and thedomain statement currently identifies cluster drives Q: and S:, update thedomain statement in your dsm.opt file as follows: domain Q: S: R:.3. You must modify the cluster scheduler service resource properties to includethis file in the list of dependent resources needed to bring this resource online.This ensures that the cluster drive resource being added is included in the newbackups, and for backups which run after a failover occurs.After the changes above are made, bring the cluster scheduler service resourceoffline, and back online. The schedule should now process this additional resourcefor backups.Q: The CAD service has been removed and now the generic service resource forthe cluster group is failing. How can this be corrected?A: The CAD can be used to control the scheduler, the Web client, or both for TivoliStorage Manager in a cluster environment. If the CAD is removed withoutupdating the generic cluster resource, the resource fails. To correct this:1. Verify which scheduler service was controlled by the CAD.2. Using the Microsoft Cluster Administrator utility or VCS Configuration Editor,go to the properties window of the service resource, select the Parameters tab,and enter the name of the correct scheduler service to use.3. Repeat steps one and two for each cluster group that was managed by thespecific CAD.4. To test the updated service resource, initiate a failure of the resource. If theresource comes back online with no failures, the update has worked properly.Note: To fully disable the CAD, remove the managedservices option from thecluster group dsm.opt file or comment it out.Configuring online-image backup supportIf the Tivoli Storage Manager online image feature is configured, Tivoli StorageManger performs a snapshot-based image backup, during which the real volume isavailable to other system applications.A consistent image of the volume is maintained during the online image backup.To configure online image backup, perform the following steps:1.
