Application HA clustering has dropped a disk... :-/
Hi,
After I completed the Application HA clustering of SQL2008 across two Windows 2008 R2 nodes, I found that the SQL installation's virtual Backup disk (M: for reference) remained on the first node after I'd initiated a switch to the second node via the High Availability tab in the vSphere Client. The other disks re-attached to the second node ok.
On closer inspection in Cluster Explorer on one of the nodes I discovered that the Mount Point for that disk was completely missing!
I attempted to manually create the Mount Point and brought the resource online in the cluster on the first node, but attempting the switch operation again failed as the virtual disk failed to re-attach to the second node.
How to fix without blatting the clustering / SQL installations?
Thanks!
Ok. let me try this again. My screenshots did not get added to my last post. Here are two images to help you find the configuration information needed and where to put that information in the Cluster GUI.
From your description, I'm also assuming that you have the other needed resource to mount the drive to M:. If not then we will need to modify or add other resources to get the drive completely accessible during failover.
Thank you,
Wally
