About Storage Foundation Cluster File System administration

The Veritas Storage Foundation Cluster File System 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, SFCFS requires the integrated set of Veritas products included in the Veritas Storage Foundation Cluster File System.

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

See the Veritas Storage Foundation Cluster File System Installation Guide.

SFCFS 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.
