We have an environment as follows:
2 node SQL Server Cluster running SQL Server 2016 instances. The failover cluster is running on Windows Server 2012 R2. All storage resides in a Compellant SAN. We have just about run out of drive letters for new instances and want to move
to mount points but I have run into an issue when trying to change the mount point volumes to Cluster Shared Volumes.
I used Microsoft Knowledgebase document 280297 and 819546 as reference to setup my Mount Points.
On each node of the cluster, I set up a mount point Root Disk and assigned it the same drive letter. Created the mount point volumes and mapped them to the Root Disk. Added the disks as disk resources for the cluster. However, I believe, I need
to change the disks as a Cluster Shared Volume resource so each node in the cluster can have access to it during a failover.
In FC Manager, I changed the mount point from Available Storage to Cluster Shared Volume. When I click on the Mount Point in Windows Explorer I get a "Location is not available" error. I then looked at the disk in Data Management and the"Mount in the following empty NTFS folder" to the Root Disk is gone.
I attempted adding the disks as CSV's in two ways, first was adding both the root disk and the mount point disk/volume as CSV's. Then I removed them both as CSV's and added only the mount point disk/volume. Either way, I get the same error.
This is my first time setting up mount points in a cluster, I have looked at so many websites and have't found any resolution. Any advice will help.
