Managing Serviceguard Sixteenth Edition, March 2009

NOTE: Check the Serviceguard/SGeRAC/SMS/Serviceguard Manager Plug-in 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.
NOTE: Do not edit configuration files for the Serviceguard-supplied packages
VxVM-CVM-pkg, SG-CFS-pkg, SG-CFS-DG-id#, or SG-CFS-MP-id#. Create
VxVM-CVM-pkg and SG-CFS-pkg by means of the cmapplyconf command. Create
and modify SG-CFS-DG-id# and SG-CFS-MP-id# using cfs* commands.
In the case of a multi-node package, if you set auto_run (page 263) to yes, an instance
can start on a new node joining the cluster. Otherwise, it will not.
