Tivoli Storage Manager for Windows: Administrator's Guide


Managing Clusters

A Windows cluster environment is a configuration of independent computing systems (termed nodes). They are connected to the same disk subsystem and as such provide a high availability solution that minimizes or eliminates many potential sources of downtime. Microsoft Cluster Server (MSCS) is software that helps configure, monitor, and control applications and hardware components (termed resources) that are deployed on a Windows cluster.

TSM is a cluster-aware application and is configured as an MSCS virtual server. The administrator uses the MSCS Cluster Administrator interface and TSM to designate cluster arrangements and define the failover pattern.

TSM is programmed to recognize and support a SCSI tape failover pattern. MSCS does not support the failover of tape devices, so it cannot be used to configure the SCSI tape failover pattern. After the configuration has been set up, it can be monitored through MSCS and the Cluster Administrator interface.

For more information about configuring and managing clusters, see Chapter 10, Configuring and Managing Clusters.
