Managing Serviceguard Sixteenth Edition, March 2009

CVM 4.1 and later with CFS
CFS (Veritas Cluster File System) is supported for use with Veritas Cluster Volume
Manager Version 4.1 and later.
The system multi-node package SG-CFS-pkg manages the cluster’s volumes. Two
sets of multi-node packages are also used: the CFS mount packages, SG-CFS-MP-id#,
and the CFS disk group packages, SG-CFS-DG-id#. Create the multi-node packages
with the cfs family of commands; do not edit the configuration file.
CVM 4.1 and later and the SG-CFS-pkg require you to configure multiple heartbeat
networks, or a single heartbeat with a standby. Using APA, Infiniband, or VLAN
interfaces as the heartbeat network is not supported.
You create a chain of package dependencies for application failover packages and the
non-failover packages:
1. The failover package’s applications should not run on a node unless the mount
point packages are already running.
In the package’s configuration file, you fill out the dependency parameter to specify
the requirement SG-CFS-MP-id# =UP on the SAME_NODE.
2. The mount point packages should not run unless the disk group packages are
running.
Create the mount point packages using the cfsmntadm and cfsmount commands.
Serviceguard names the mount point packages SG-CFS-MP-id#, automatically
incrementing their ID numbers. In their configuration file, Serviceguard specifies
the dependency on the disk group packages.
3. The disk group packages should not run unless the CFS system multi-node package
(SG-CFS-pkg) is running to manage the volumes.
Create the disk group packages with the cfsdgadm. command. Serviceguard
names them SG-CFS-DG-id#, automatically incrementing their ID number. In
