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 Veritas Storage Foundation Cluster File System High Availability.

To configure a cluster, SFCFSHA requires the Veritas 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 Veritas Storage Foundation Cluster File System High Availability Installation Guide.

SFCFSHA also requires the cluster functionality (CVM) of the Veritas Volume Manager (VxVM) to create the shared volumes necessary for mounting cluster file systems.

For more information on these products, refer to the Veritas Volume Manager and Veritas Cluster Server documentation.
