This ensures that the backup-archive client correctly manages all disk resources,regardless of which cluster node owns the resource at the time of backup.Step 1: Identify the cluster groups to manageUse the Microsoft Cluster Administrator utility or VCS Configuration editor todetermine which groups contain physical disk resources for the backup-archiveclient to process.Register a unique node name on the backup server for each group.For example, MSCS cluster mscs-cluster contains the following groups <strong>and</strong>resources:v group-a - Contains physical disk q: (quorum), <strong>and</strong> physical disk r:Note: VCS does not have quorum disk.v group-b - Contains physical disk s:, <strong>and</strong> physical disk t:In this example, the administrator registers two node names: mscs-cluster-group-a<strong>and</strong> mscs-cluster-group-b. For example, to register mscs-cluster-group-a theadministrator can enter the following comm<strong>and</strong>:register node mscs-cluster-group-a Step 2: Configure the client options fileConfigure the client options file (dsm.opt) for each cluster group. Locate the optionfile on one of the disk drives that are owned by the cluster group.For example, the option file for mscs-cluster-group-a should reside on either q: orr:.To configure the dsm.opt file for each cluster group, specify the following options:nodenameSpecify a unique name. For example:mscs-cluster-group-adomainSpecify the drive letters for the drives which are managed by the group.For example:q: r:See “Frequently asked questions” on page 60 for information on how toadd a cluster drive to an existing Tivoli Storage Manager cluster schedulerservice resource for backup.clusternodeSpecify the Yes value. If you set the clusternode option to yes, TivoliStorage Manager:1. Checks for a cluster environment (MSCS or VCS).2. Uses the cluster name instead node name for file space naming <strong>and</strong>encryption. This allows the use of one password file for all nodes in thecluster.3. Builds a list of shared volumes <strong>and</strong> works only with shared volumes.Back up of local volumes not permitted if the clusternode option set toyes.Important: For the VCS, cluster database processing is skipped becauseVCS does not have a cluster database.
