Configuring Veritas Multi-node Packages
There are two types of multi-node packages that work with the Veritas
Cluster File System (CFS): SG-CFS-DG-id# for disk groups, which you
configure with the cfsdgadm command, and SG-CFS-MP-id# for mount
points, which you configure with the cfsmntadm command. Each package
name will have a unique number, appended by Serviceguard at creation.
Serviceguard automatically creates each package’s configuration file, its
run and halt scripts, and its control script.
Serviceguard automatically applies the configuration when you enter
cfsdgadm or cfsmntadm.
NOTE Veritas Cluster Volume Manager and Cluster File System are supported
on some, but not all current releases of HP-UX. Check the latest Release
Notes for your version of Serviceguard for up-to-date information
(http://www.docs.hp.com -> High Availability ->
Serviceguard).
CAUTION Once you create the disk group and mount point packages, it is critical
that you administer these packages with the cfs commands, including
cfsdgadm, cfsmntadm, cfsmount, and cfsumount. These non-cfs
commands could cause conflicts with subsequent command operations on
the file system or Serviceguard packages. Use of these other forms of
mount will not create an appropriate multi-node package which means
that the cluster packages are not aware of the file system changes.
The package can be configured to run on a subset of the cluster nodes. It
can be halted or started on a specific node or nodes.
NOTE The disk group and mount point multi-node packages do not monitor the
health of the disk group and mount point. They check that the packages
that depend on them have access to the disk groups and mount points. If
