Unable to backup SQL Server from a newly added clustered drive We have a clustered SQL server, and the backups of the databases are stored on the same drive where the data files are(F:). The storage team finally acted on my request to have a new clustered drive solely for SQL backups(G:). When I try to backup the database on the backup folder on the new clustered drive I get an error:

Cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists.
If you know that the service account can access a specific file, type in the full path for the file in the File Name control in the Locate dialog box.

I have already:


Assigned the cluster disk to SQL Server in WSFC
Added the SQL Server service account in the Security on the disk properties, and has been inhereted by the children
Changed the database settings on the instance properties to have the new path for backup


Is there anything else that i missed? I still cant backup to the new clustered disk. Does this process require a server restart?
When adding clustered disk to an instance of SQL Server, there are a few steps that need to be taken.


Present the disk to all possible owners of that disk (nodes)
Bring the disk online from the first node that will own it
Bring the disk into the cluster - it'll now reside in available storage
Move the disk into the resource group for SQL Server
Set the SQL Server resource to DEPEND on that new disk
Double check sys.dm_io_cluster_shared_drives to see that SQL "sees" the disk. If it doesn't, one of the steps above was not successfully completed.


In this case, step 5 was missed which is why it didn't show up in the DMV listed in step 6.
