The VERITAS Cluster File System (CFS) 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, CFS requires the integrated set of VERITAS products included in the
VERITAS Storage Foundation Cluster File System (SFCFS).
To configure a cluster, CFS requires select HP Serviceguard Storage Management Suite bundles.
The Low Latency Transport (LLT) package provides
node-to-node communications and monitors network communications. The Group
Membership and Atomic Broadcast (GAB) package provides cluster state, configuration,
and membership service, and monitors the heartbeat links between systems to ensure that
they are active. In HP Serviceguard Storage Management Suite environments, Serviceguard
configures and controls GAB and LLT.
CFS also requires the cluster functionality (CVM) of the VERITAS Volume Manager
(VxVM) to create the shared volumes necessary for mounting cluster file systems.
Note To install and administer cluster file systems, you should have a working
knowledge of VxVM. To install and administer application failover functionality,
you should have a working knowledge of Serviceguard.
