Table 10 describes how to verify each cluster and package component, the command or tool to
use and its description.
Table 10 Verifying Cluster and Package Components
DescriptionTool or Command; More InformationComponent (Context)
Verifies for the following:
• existence
• availability across all the nodes
where the package is
configured to run.
• same physical volumes across
all the nodes where the
package is configured to run.
• same volume group across all
the nodes where the package
is configured to run.
NOTE: The volume group
verifications are ignored in
serviceguard-xdc and Metrocluster
environment.
cmcheckconf (1m), cmapplyconf
(1m)
See also “Verifying the Cluster
Configuration ” (page 174).
Volume groups (package)
Verifies whether the volume group
activation protection is enabled in
the lvm.conf file. For more
information, see “Enabling Volume
Group Activation Protection”
(page 156)
cmcheckconf (1m), cmapplyconf
(1m)
Volume group activation protection
(cluster)
Verifies for the consistency of the
volume groups and physical
volumes of the volume group
across all the nodes where the
package is configured to run.
cmcheckconf (1m), cmapplyconf
(1m)
LVM physical volumes (package)
These commands verify that the
quorum server, if used, is running
and all nodes are authorized to
access it; and, if more than one IP
address is specified, that the
quorum server is reachable from
all nodes through both the IP
addresses.
cmcheckconf (1m), cmapplyconf
(1m).
Quorum Server (cluster)
These commands verify if all the
cluster nodes are configured to use
the same device as lock LUN and
that the lock LUN device file is a
block device file.
cmcheckconf (1m), cmapplyconf
(1m)
Lock LUN (cluster)
