You can install locally on each node of a Microsoft Cluster Server (MSCS) environment cluster. You can also install and configure the Scheduler Service for each cluster node to manage all local disks and each cluster group containing physical disk resources.
For example, cluster mscs-cluster contains two nodes: node-1 and node-2, and two cluster groups containing physical disk resources: group-a and group-b. In this case, an instance of the TSM Backup-Archive Scheduler Service should be installed for node-1, node-2, group-a, and group-b. This ensures that proper resources are available to the Backup-Archive client when disks move (or fail) between cluster nodes.
The clusternode option ensures that TSM manages backup data logically, regardless of which cluster node backs up a cluster disk resource. Use this option for TSM nodes that process cluster disk resources, and not local resources. See Clusternode for more information.
