Table 10 Verifying Cluster Components (continued)
CommentsTool or Command; More InformationComponent (Context)
Commands check 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)
Commands check that all nodes
are be accessing the same
physical device and that the lock
LUN device file is a block device
file
cmcheckconf (1m), cmapplyconf
(1m)
Lock LUN (cluster)
To check file consistency across all
nodes in the cluster, do the
following:
Commands check that the
mount-point directories specified
in the package configuration file
exist on all nodes that can run the
package.
cmcheckconf (1m), cmapplyconf
(1m)
See also “Verifying the Package
Configuration” (page 229).
Mount points (package)
Commands check that files
specified by service commands
exist and are executable. Service
commands whose paths are nested
within an unmounted shared file
system are not checked.
cmcheckconf (1m), cmapplyconf
(1m)
See also “Verifying the Package
Configuration” (page 229).
Service commands (package)
Commands check that all IP
addresses configured into the
cluster are in each node's /etc/
hosts.
cmcheckconf (1m), cmapplyconf
(1m)
IP addresses (cluster)
cmcheckconf (1m), cmapplyconf
(1m)
See also “Verifying the Package
Configuration” (page 229).
Package IP addresses (package)
For LVM only, commands check
that file systems have been built on
the logical volumes identified by
the fs_name parameter
(page 181).
cmcheckconf (1m), cmapplyconf
(1m)
See also “Verifying the Package
Configuration” (page 229).
File systems (package)
cmcheckconf (1m), cmapplyconf
(1m)
See also “Verifying the Package
Configuration” (page 229).
Generic resources (package)
A non-zero return value from any
script will cause the commands to
fail.
cmcheckconf (1m), cmapplyconf
(1m)
External scripts and pre-scripts
(modular package)
