Transition from PSSP to cluster systems management (CSM)

This IBM Redbooks publication covers the process of converting a PSSP cluster to a CSM cluster. It examines the different tools, utilities, documentation and other resources available to help the system administrator move a system from PSSP to CSM. It also examines the different paths a customer can...
