Hi,
I need to use the PreOffline Service Group attribute. It is a feature not
fully documented. In particular I need to know how to set the preoffline
script.
The user guide says only:
PreOffline
(system use only)
boolean-scalar If set to 1, VCS calls a predefined script,
preoffline, before taking the service group offline.
Users can then decide whether to continue the
offline procedure or cancel it.
Thanks in advance for every hints.

OK - so you have to do 2 things:
1. put a script in /opt/VRTSvcs/bin/triggers and call it PreOffline
(also make it executable - look at the sample trigger scripts in
/opt/VRTSvcs/bin/sample_triggers)
2. Next you have to tell VCS that you want the trigger to be executed
for a service group. So this is where you set the PreOffline value to 1
for the SG (in simple language - say your service group is called MySG,
then you issue the following commands on any node in the cluster:
haconf -makerw
hagrp -modify MySG PreOffline 1
haconf -dump -makero
All of the above is in the Admin Guide

This flag was not documented in VCS 2.0 and I use VCS 4.0.
Sometimes I lose myself in trivial particulars. :-)

I tried your suggestions. But, when I tried the manual switch of SG, I got
this warnings:
------start warning-------

-----end warning-------
and the SG did not make the manual switch.
I have renamed the script "PreOffline" in "preoffline", but the problem remains.
I find out that hatrigger is a script - may be a perl script, I do not know
perl - and, IMHO, it doesn't handle the flag "-preoffline". May be that is
this the problem?
Or do I forget some "trivial" particular? :-)
