Thanks! Because we have many applications and softwares on linux, maybe
some of them have pending stop, or maybe some have problem to fail stop.
Even though I set a big timer, it is possible that system shutdown is prior
to software's normal stop. How to solve this situation?
Best Regards!

CP SIGNAL SHUTDOWN causes the standard Linux shutdown process to be
executed, through
the init scripts.
If the software you mention contains quiesce or shutdown commands in the
init scripts,
it will be executed with SIGNAL SHUTDOWN.
The big question then is of the time frame. Is 90 seconds enough time to
guarantee that
the software is all shutdown before CP pulls the rug out from under the
virtual machine?
THAT is what you need to make sure of. Your shutdown timer may have to be
changed.
The shutdown timer can be set system wide, so that it does not need to be
specified on
each command.
