The Storage Foundation Cluster File System High Availability (SFCFSHA) is a shared file system that enables multiple hosts to mount and perform file operations concurrently on the same file. To operate in a cluster configuration, SFCFSHA requires the integrated set of Veritas products included in the Storage Foundation Cluster File System High Availability.

To configure a cluster, SFCFSHA requires the Cluster Server (VCS). VCS supplies two major components integral to SFCFSHA. The LLT RPM provides node-to-node communications and monitors network communications. The GAB RPM provides cluster state, configuration, and membership service, and monitors the heartbeat links between systems to ensure that they are active. There are several other RPMs supplied by VCS that provide application failover support when installing SFCFSHA.

See the Storage Foundation Cluster File System High Availability Installation Guide.

For more information on VCS, refer to the Cluster Server documentation.
