Compatibility with General Parallel File System

It is mandatory that the CSM client RPM be installed either on all of the General Parallel File System for Linux (GPFS) nodes or on none of them. The Resource Monitoring and Control (RMC) subsystem requires that the definitions of its resource classes be the same on all nodes within the GPFS cluster. If the CSM client RPM is installed on only some of the GPFS nodes, some of the RMC daemons will not be able to join their peer group successfully, an undesirable situation. The CSM management server node should not be part of the GPFS cluster because it adds other resource classes to RMC, and it is not practical or desirable to install the CSM server RPM on all of the GPFS nodes.

GPFS and CSM should be using the same level of RSCT code. The current release of RSCT is Version 2.2.1.0.
