Error Code details
Severity: Error 
Component: Cluster Server 
Exiting: Another copy of VCS may be running

The error message appears when a user starts the /opt/VRTSvcs/bin/had program if the /opt/VRTSvcs/bin/had process is already running.


A system can only run one instance of the Veritas Cluster Server (VCS) high availability daemon (HAD). If another instance starts, the second process determines that an instance is already running, and it exits with the message above.

Usually this is not an issue. You may accidently start Veritas Cluster Server (VCS) and then see the error message. But if your high availability operations are running properly, there is no reasons for concern. However, if you find this message when you deliberately start VCS, and you get no response to ha commands, follow the steps below to fix this issue:

  1. Check if an instance of the HAD process is running using this command:

              # ps –ef | grep had

  1. If the HAD process is running, check the system state using this command:

    # hasys -state

    Please try the command a few times. If the local system is in RUNNING state, no action is  required. Otherwise check the /var/VRTSvcs/log/engine_A.log file for any errors.

  2. If the HAD process is not running, check if /var/VRTSvcs/lock/.hadtrylock2 is present as a leftover from a previous issue. If it exists, delete it and start VCS again.
