CommentsTool or Command; More InformationComponent (Context)
Commands check that the
disk(s) are accessible from all
nodes, and that the lock
volume group(s) are activated
on at least one node.
cmcheckconf (1m), cmapplyconf
(1m)
Lock disk(s) (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:
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 each
node has a working physical
connection to the disks.
cmcheckconf (1m), cmapplyconf
(1m)
See also “Verifying and Applying the
Package Configuration” (page 317).
VxVM disk groups (package)
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 and Applying the
Package Configuration” (page 317).
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)

Package Configuration” (page 317).
