RE: [ActiveDir] Change private IP on a cluster

Mon, 05 Jun 2006 07:15:31 -0700

Thanks Jose,

This is just going to affect the private IPs in the cluster so no name resolution issues will come into play.

 

This helped a lot. It lead me to http://support.microsoft.com/kb/241828/ which is pretty clear. I’m looking at some downtime on the cluster and that’s what I needed to know. I was *assuming* that when I changed the IP on both private interfaces the cluster would come back up and there would be no downtime but it looks like that’s not going to be the case L

 

Last quick question. The article states there may be a failover if I change the IP and subnet. Do you think the cluster will fail over if I just change the IP and don’t change the subnet?

 

Thanks again, I appreciate the help.

Hi Mike,

 

I've only had to change a SQL 2000 Active / Active Cluster IP and it involves some additional steps for SQL Virtual Names. It's been over 5 years since I built an Exchange 2000 cluster, but I do not recall if Exchange has any dependencies (I would probably post this to the Exchange list and I am cc'ing them as well)

 

Take a look at :

Exchange Server 2003 Cluster Configuration Checklist

 

Changing the IP address of network adapters in cluster server

 

 

Also just in case you ever have to change it on a SQL:

 

How to change the network IP addresses of SQL Server virtual servers

 

Hope this helps,


Sincerely,

Hey,
I have an Exchange 2003 active/passive cluster on Windows 2003 and I need
to change the private ip on both nodes. I realize that while I'm
changing the IP the nodes will not talk to each other and likely kick
the passive node off or stop the cluster service for a few minutes on
the passive node.

Is there anything else I will need to do or look out for? I don't
*think* this is a big deal but since it's a production cluster, and I've
never had to do this, I thought I would check before I tried it.

Thanks again.

Mike.
