Failover cluster site name under nodes page shows old site name

James Edmonds 821

Hi,

I deployed a two node cluster, and later changed our Active Directory site name.
A new cluster I deployed shows the new site name on each node when looking at the nodes page, but the old cluster still shows the old site name for both nodes.

Is there a way to force the cluster to refresh the site name, or manually adjust it?

Thanks
James

Hi,

Check the current AD site in each node of old cluster by runing this command :

nltest /dsgetsite

A reboot will refresh all closest AD site and active directory.
Try launch a reboot of old cluster nodes , if their subnet is attached to new AD site and the command below still showing the old AD site.

Hi,

Running that command on both nodes shows the new site name.
Even after rebooting the nodes, WSFC manager still shows these nodes as having the old site name. The subnet is correct as there is only one site and one subnet.

Any other suggestions on how I can amend this in WSFC manager?

Many thanks
James

There is no manual modification from WSFC manager. The old nodes seem able to contact the closest DCs in closest site.
If WSFC manager still still showing the old site name , you can neglect it.

Is it something that is only set at cluster creation?

Seems odd if that's the case, as if a node is moved to another site, then it should update?

Any other way you can think to trigger it to update?

Cheers

Yes.

No, I have the same behavior in my environment.

Try to remove and add again nodes to the cluster. I can update it.
The last solution is to destroy the cluster and rebuild it, but I think it's not necessary because it will not impact your cluster if you keep the old site in cluste wizard.

Well sadly removing and re-adding a node has not changed the site name shown for that node.

It may not be impacting, but it does seem strange for this not to update to reflect the nodes actual site.
I may be giving too much attention to this, but if it's going to tell me the site name, it ought to be correct otherwise I don't see the point in showing it.
