Veritas InfoScale 7.4.1 Patch 1200 Release Notes - Linux
Changes related to Cluster Server
The following changes are made to the Cluster Server (VCS) component.
By default, when VCS is stopped as part of a system restart operation, the active service groups on the node are migrated to another cluster node. In some cases, you may not want to evacuate the service groups during a system restart. For example, you may want to avoid administrative intervention during a manual shutdown. InfoScale now lets you choose whether or not to evacuate service groups when VCS is stopped.
A new environment variable, NOEVACUATE, is introduced to specify whether or not to evacuate service groups when a node is shut down or restarted.
The default value of NOEVACUATE is 0, which specifies that the service groups should be evacuated when VCS is stopped.
The service groups are evacuated by executing the following command, before the system is stopped:
hastop -local -noautodisable
If this value is set to 1, the VCS stop script does not evacuate the service groups.
The service groups evacuation is skipped because the following command is executed, depending on the VCS time-out value:
hastop -sysoffline -noautodisable
This variable is present in the /etc/sysconfig/vcs file.
By default, the CmdServer process runs as a daemon. It starts as soon as VCS starts, and you cannot disable the daemon. InfoScale now lets you disable the CmdServer daemon.
A new environment variable, STARTCMDSERVER, is introduced to specify whether to disable CmdServer.
The default value of STARTCMDSERVER is 1, which indicates that the
CmdServerstarts as a daemon process when HAD starts and then runs as a background process.If this value is set to 0, the VCS start script does not start
CmdServerwhen the HAD starts.
This variable is present in the /etc/sysconfig/vcs file.
