HP Serviceguard A.11.20 Release Notes, September 2012

NOTE:
• All of the checks below are performed when you run cmcheckconf (1m) without any
arguments (or with only -v, with or without -k or -K). cmcheckconf (1m) validates the
current cluster and package configuration, including external scripts and pre-scripts for modular
packages, and runs cmcompare (1m) to check file consistency across nodes. (This new
version of the command also performs all of the checks that were done in previous releases.)
• These new checks are not done for legacy packages. For information about legacy and
modular packages, see chapter 6 of Managing Serviceguard.
• LVM volume groups:
Check that each volume group contains the same physical volumes on each node◦
◦ Check that each node has a working physical connection to the physical volumes
◦ Check that volume groups used in modular packages are cluster-aware
• LVM logical volumes
◦ Check that file systems have been built on the logical volumes identified by the fs_name
parameter in the cluster's packages.
• VxVM disk groups:
Check that each disk group contains the same number of disks on each node.◦
◦ Check that each node has a working physical connection to the disks.
• File consistency:
◦ Check that files including the following are consistent across all nodes:
– /etc/hosts (must contain all IP addresses configured into the cluster)
– /etc/nsswitch.conf
– /etc/services
– package control scripts for legacy packages (if you specify them)
– /etc/cmcluster/cmclfiles2check
– /etc/cmcluster/cmignoretypes.conf
– /etc/cmcluster/cmknowncmds
– /etc/cmcluster/cmnotdisk.conf
– user-created files (if you specify them)
For more information, see “Checking the Cluster Configuration and Components” in chapter 7 of
Managing Serviceguard.
Limitations

• Access Control Policies properly configured (see chapter 5 of Managing Serviceguard for
information about Access Control Policies)
• File systems configured to mount automatically on boot (that is, Serviceguard does not check
/etc/fstab)
• Shared volume groups configured to activate on boot
