LLT provides kernel-to-kernel communications and monitors
network communications for CFS.
• vxfend - When VERITAS CFS is deployed as part of the
Serviceguard Storage Management Suite, the I/O fencing daemon
vxfend is also included. It implements a quorum-type functionality
for the VERITAS Cluster File System. vxfend is controlled by
Serviceguard to synchronize quorum mechanisms.
• cmvxd - The Serviceguard-to-VERITAS daemon coordinates the
membership information between Serviceguard and VERITAS'
Clustered File System product. (Only present when VERITAS CFS is
installed.)
• cmvxping - The Serviceguard-to-VERITAS daemon activates
certain subsystems of the VERITAS Clustered File System product.
(Only present when VERITAS CFS is installed.)
