Is there proper steps to take to a node in the cluster when you are going to reboot the server..
Like take the node out of the two node cluster ?? or stop certain services before hand?
Thanks

Re: Red Hat Clustering - Steps to Apply Maintenance
fail all packages over to the node not being upgraded.
Do any patches or rpm installs you need to do.
reboot the node. Hopefully it will rejoin the cluster and you can fail all packages over to it and repeat the process on the second node.
If not, you will have to have a little down time to get the cluster running on the first node, once all services are running you should be able to update node 2 without too much trouble.
Note: read the notes carefully. Cluster suite updates come out late and do not always work with the latest red hat kernel.

SolutionFor a Red Hat cluster (from http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/pdf/Cluster_Administration.pdf)
To stop the cluster software on a member, type the following commands in this order:
1. service rgmanager stop
2. service gfs stop, if you are using Red Hat GFS
3. service clvmd stop, if CLVM has been used to create clustered volumes
4. service cman stop
Stopping the cluster services on a member causes its services to fail over to an active member.
