The solution you use for your installation depends on your own specific
requirements. For more information about requirements and types of installations,

Monitoring and updating an IBM ServeRAID cluster solution
Note: Cluster configurations apply only to the ServeRAID-4H controller.
You can use the ServeRAID Manager program to check the ownership of a physical
drive on another server or to add or remove a logical drive in the cluster. The
ServeRAID Manager program supports three features for cluster functions:
• Validate cluster
• Configure for clustering
• View shared drives.
Note: Make sure that the ServeRAID Manager program is installed on the server.
