Checking HACMP components

Checking cluster services and processes

Check the status of the following HACMP daemons:

• The Cluster Manager (clstrmgrES) daemon
• The Cluster Communications (clcomdES) daemon
• The Cluster Information Program (clinfoES) daemon.

When these components are not responding normally, determine if the daemons are active on a cluster node. Use either the options on the SMIT System Management (C-SPOC) > Manage HACMP Services > Show Cluster Services panel or the lssrc command.

For example, to check on the status of all daemons under the control of the SRC, enter:

lssrc -a | grep active
 syslogdras 290990active
 sendmail  mail270484active

To check on the status of all cluster daemons under the control of the SRC, enter: lssrc -g cluster

Note: When you use the -g flag with the lssrc command, the status information does not include the status of subsystems if they are inactive. If you need this information, use the -a flag instead. For more information on the lssrc command, see the man page.

To view additional information on the status of a daemon run the clcheck_server command. The clcheck_server command makes additional checks and retries beyond what is done by lssrc command. For more information, see the clcheck_server man page.

To determine whether the Cluster Manager is running, or if processes started by the Cluster Manager are currently running on a node, use the ps command.

For example, to determine whether the clstrmgrES daemon is running, enter:

ps -ef | grep clstrmgrES
root  18363  3346  3 11:02:05 -  10:20 /usr/es/sbin/cluster/clstrmgrES
root  19028  19559 2 16:20:04 pts/10  0:00 grep clstrmgrES
