Note: If there is an unresolvable label in the /usr/es/sbin/cluster/etc/rhosts file,
then all clcomdES connections from remote nodes will be denied.

cluster manager clstrmgrES

cluster multi peer extension communication daemon (clsmuxpdES)

The clcomdES is used for cluster configuration operations such as cluster synchronisation
cluster management (C-SPoC) * Dynamic re-configuration DARE configuration. (DARE ) operation.

For clcomdES there should be atleast 20 MB free space in /var file system.
/var/hacmp/clcomd/clcomd.log --it requires 2 MB
/var/hacmp/clcomd/clcomdiag.log --it requires 18MB
Additional 1 MB required for
/var/hacmp/odmcache directory

clverfify.log also present in /var directory
/var/hacmp/clverify/current//* contains log for mcurrent execution of clverify
/var/hacmp/clverify/pass//* contains logs from the last passed verification
/var/hacmp/clverify/pass.prev//* contains log from the second last passed verification
