Failing over Exchange (urgent)

Running Exchange 2007 SP2 on Windows 2008 Server SP2, SCC Active/Passive nodes (nodea.domain.com and nodeb.domain.com, cms cms.domain.com).

Currently, cms.domain.com is on nodea.domain.com. I want to fail this over to nodeb.domain.com so I can replace a part on nodea.domain.com

I was thinking:

1. Use Exchange Management Console (Clustered Mailbox Properties) to move CMS from nodea to nodeb just before maintenance time.

Problem is - this will leave the Quorum on nodea.domain.com.

Will this cause an issue? Is it ok for the quorom to move to nodeb when I shut down nodea? How else can I move it? If I go to Failover Cluster Management > Services and Applications, then there is only one application listed there, the CMS. I can't see how I can move the Quorum without rebooting the server itself.

What do you mean with "this will leave the quorum on node A"?

Are you saying that the FSW is "installed" on one of the nodes?
If so, you can use the cluster.exe cmd-line tool to move the resource.

Sorry, no the FSW is not installed on a node. I meant this will leave the quorum owned by Node A.

Okay, I got it now.

What you should do, prior to failing over is moving the quorum from node A to node B.
You can do this as well using the cluster-cmdline tool.

I think (out of my head) it's in the cluster > res (resource)

Thanks Michael.

Out of interest, why not -

1. Fail over Exchange using EMC
2 Reboot Node A so that Quorum moves to Node B automatically

What's the benefit of moving the Quorum *before* failing over Exchange?

kam_uk,

I just answered your questions ;-)
maybe my english isn't 100% and cause some confusion, sorry for that.

l this cause an issue? Not necessarily. as you said, you could fail over and reboot.
Is it ok for the quorom to move to nodeb when I shut down nodea? How else can I move it? --> cluster.exe to
I can't see how I can move the Quorum without rebooting the server itself. --> cluster.exe
