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. See “Creating a Storage
Infrastructure with Veritas Cluster File System (CFS)” on page 251.
NOTE Check the Serviceguard, SGeRAC, and SMS Compatibility and Feature
Matrix and the latest Release Notes for your version of Serviceguard for
up-to-date information about support for CFS
(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 using the cfs commands, including
cfsdgadm, cfsmntadm, cfsmount, and cfsumount. Non-CFS commands
could cause conflicts with subsequent command operations on the file
system or Serviceguard packages.
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
the dependent application package loses access and cannot read and
write to the disk, it will fail; however that will not cause the DG or MP
multi-node package to fail.
