We recently had a hardware issue with a server in a 3 node cluster which ended up with us having to rebuild the server from Ignite.
During this recovery we had to stop the Serviceguard cluster as we experienced a TOC on the remaining 2 nodes.
The shared disks and IP addresses were then manually configured / mounted on one of the 2 remaining nodes. (after doing a vgchange -c n)
We are now in a position to restart the Serviceguard cluster and add the packages back one at a time.
My questions are:
1. How do we stop Serviceguard from trying to mount the packages automatically when it starts? (cmruncl)
2. As we have done a vgchange -c n on the volume groups, will this prevent Serviceguard mounting the volume group (we could use this to prevent Serviceguard running the packages that are still manually mounted)
This is a 24 x 7 production system and we only have downtime for 1 package at a time. Therefore I would appreciate any other comments on how we can return to Serviceguard in a controlled mannner.
Thanks for your help.

SolutionWhat is the status of cluster now ? running or down???
If it is stopped & want to run this ...
Start the cluster with cmrunnode command not cmruncl... Normally cmruncl starts packages too..
If you run cmrunnode on all nodes they will start cluster daemons & from cluster..
After this you can start individual packages on desired node.
Ensure that you have made the pkg vg in cluster aware before starting pkg manually.

Re: How to prevent Serviceguard mounting disks that have been manually mounted
You have to do
#vgchange -a n
#vgchange -c y
to make vgs cluster aware.

Mark,
I belive you have to set AUTO_RUN=NO is the
package configuration file .
In that case you should run cmrunpkg manually to activate the package/resources.

Aneesh

Re: How to prevent Serviceguard mounting disks that have been manually mounted
Thank you for the quick reply.
The cluster is currently down.
We usually do the cmruncl (sometimes cmruncl -n
I will try the cmrunnode on each server as you suggested.

Re: How to prevent Serviceguard mounting disks that have been manually mounted
Ensure that you run cmrunnode on atleast 2 nodes.
execute cmrunnod on single node won't start cluster. it will wait for another node to join
