CFS enables multiple hosts to mount and perform file operations concurrently on the

same storage device. To operate in a cluster configuration, CFS requires the integrated

set of Veritas ™ products by Symantec that are included in the HP Serviceguard Storage

Management Suite.

CFS includes Low Latency Transport (LLT) and Group Membership Atomic Broadcast

(GAB) packages. The LLT package provides node-to-node communications and monitors

network communications. The GAB package provides cluster state, configuration, and

membership services. It also monitors the heartbeat links between systems to ensure

that they are active.

There are other packages provided by HP Serviceguard that provide application failover

support when you install CFS as part of a high availability solution.

CFS also requires the cluster volume manager (CVM) component of the Veritas™

Volume Manager (VxVM) to create the shared volumes necessary for mounting cluster

file systems.

NOTE To install and administer CFS, you should have a working knowledge of cluster file

systems. To install and administer application failover functionality, you should have a

working knowledge of HP Serviceguard. For more information on these products, refer to

the HP Serviceguard documentation and the Veritas™ Volume Manager (VxVM)

documentation available in the /usr/share/doc/vxvm directory after you install CFS.
