Thanks to
Rita Workman
Copeland, Daniel
Stocker, Nick
There were few suggestions:
- VG is not included in the cmclconf.ascii
- Some processes block the VG to be de-activated during the package stop
- VG is included in the /etc/lvmrc and is activated during the boot of the
server.
None of those were correct.
So the behaviour still remains a mystery. I have logged a call at HP.
If they come out with some explanation I will make a second summary.
Thank you very much
Zdravko

Subject: [HPADM] Strange vgchange behaviour
Hi admins,
We have a monstrous ServiceGuard cluster running 28 packages.
>From time to time we experience a very strange problem with it.
We have scheduled package switches in some round robin manner which causes
the packages to go to a different node every 6 weeks.
>From time to time we experience some strange behaviour: a (not a specific
one) volume group will fail to activate with "Activation mode conflicts with
the configured mode".
We execute vgchange -c y and it works again.
I always assumed that during the last 6 weeks something has changed on that
VG and that resulted somehow in changing the "c" bit.
Last night we have had again that problem and fortunately I was able to
track the complete sequence from the last successful package switch up to
now.
To my surprise there were no changes at all for that VG.
Has someone experienced some similar problem?
The HW is 4xN-class with Tachion FC cards connected to EMC over some brocade
switches.

Thanks in advance
