For more information about requirements and types of installations, refer to the IBM Shared Disk Clustering Hardware Reference. You can obtain this publication from the IBM Support Web site. See "Downloadable files from the World Wide Web" on page 163 for additional information. 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. 176 Hardware Maintenance Manual: Netfinity 7600 - Type 8665 Models 1RY, 2RY
