Ability to stop VCS without evacuating service groups

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. This variable is present in the /etc/default/vcs file.

For details, refer to the Cluster Server 7.4.2 Administrator's Guide - AIX.
