Server 2K8 HA cluster. How to add a new mount point to an existing cluster resource?

    Question

  • I have a 3 node 2K8 R2 Enterprise Edition cluster housing multiple SQL Server 2K8 resources. I need to add additional space in the form of a new mount point under the existing drive letter that is already under cluster control. However in the disk management the drive letter isn't accessible since it is under cluster control, and under cluster there doesn't appear to be any way to add storage except to use a new drive letter, which we do not want to do for various reasons...

    I have a dev environment set up so breaking it is no big deal as long as I break the dev and NOT production I am willing to try just about anything that might work...

    So without going into too much boring detail, it's a 3 node 2K8 R2 EE cluster, in VMWare so no real hardware to speak of. The storage is off on a BMC AX500 I believe... Multipathing is PowerPath.

    I admit to being a bit rusty in Windows native clustering. Been working with Veritas Storage Foundation HA on Windows since Server 2000... Got most of it figured out except this one, and it's a whopper for us...

    Thanks in advance for any help you can offer.

  • Yes, I read that article. Working my way through my reply to you I figured it out. You have to bring the disk online in the resource group and then go back OUT to the disk management on the node that is controlling it and THEN it will let you add the storage...
