Indicates that when the HAD should call a user-defined script before bringing a service group online in response to the
hagrp -online command or a fault.
If the trigger does not exist, VCS continues to bring the group online. If the script returns 0 without an exit code, VCS runs the
hagrp -online -nopre command, with the
-checkpartial option if appropriate.
If you do want to bring the group online, define the trigger to take no action. This event trigger is configurable.
