Table 5 Verifying Cluster Components (continued)
CommentsTool or Command; More InformationComponent (Context)
To check file consistency across all
nodes in the cluster, do the
following:
1. Customize /etc/cmcluster/
cmfiles2check
2. Distribute it to all nodes using
cmsysnc (1m)
3. run cmcheckconf -C
For a subset of nodes, or to check
only specific characteristics such
as ownership, content, etc., use
cmcompare (1m).
cmcheckconf (1m), cmcompare (1m).
IMPORTANT: See the manpage for
differences in return codes from
cmcheckconf without options versus
cmcheckconf -C.
File consistency (cluster)
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)
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
filesystem are not checked.
cmcheckconf (1m), cmapplyconf
(1m)
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)
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.
cmcheckconf (1m), cmapplyconf
(1m)
File systems (package)
Commands check that configured
resources are available on each
node that can run the package.
cmcheckconf (1m), cmapplyconf
(1m)
EMS 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)
Checked for modular packages
only, as part of package validation
(cmcheckconf -P).
cmcheckconf (1m), cmapplyconf
(1m)
SGeRAC Toolkit files consistency
(package)
Checked for modular packages
only, as part of package validation
(cmcheckconf -P).
cmcheckconf (1m), cmapplyconf
(1m)
Cluster Interconnect subnet (package)
Setting up Periodic Cluster Verification
You can use cron (1m) to run cluster verification at a fixed interval. Specify the commands to
run in a crontab file (see crontab (1)).
