Problem Backing up Clustered Storage

I have a server that is connected with SAS to a storage area that's also used for a failover cluster. This is an inherited setup which was not documented. So, the digital asset management system has a volume which is presented to Windows as if it's clustered storage - it's a volume without a drive letter and it doesn't appear anywhere other than disc administrator. The only volumes visible to the backup (Veeam agent) are C and E, and this Mounted Volume appears on E.

I have realised that this configuration doesn't successfully back up my files. I've got another file server with more or less the same hardware (Proliant DL380 gen 9/10 and an HPE MSA 2040/2050) but the storage is direct attached.

The colleague who set this up suggested that I talk to the maker of the DAMS, but obviously that's not going to get me anywhere... Is there an easy way to convert a mounted volume into a direct attached storage? I am assuming that assigning a drive letter (an option in Disk Administrator) is not going to do any good...

    Hi Tim,

    You have posted in the general Windows Server forum, since your issue is related to Clustering I suggest you ask over at the dedicated Windows Server Clustering forum over here:
    https://learn.microsoft.com/en-us/answers/topics/windows-server-clustering.html

    (If the reply was helpful please don't forget to accept as answer, thank you)

    Best regards,

    You can add the tag 'windows-server-clustering' to your original post to get the clustering experts involved.

    But, a better explanation of your configuration would be helpful. What does "I have a server that is connected with SAS to a storage area that's also used for a failover cluster" mean? Is the server you are asking about part of a cluster? From the above statement, I'm not sure. It sounds like you have a server connected to a SAS storage array, and the storage array is also used for a cluster. But I am not sure if the server you are talking about is part of that cluster or if the server is a standalone server.

    Hi,
    What does "convert a mounted volume into a direct attached storage" mean? Do you want to assign a drive letter to a volume currently added to CSV and mounted at C:\ClusterStorage? If yes, you could open Failover Cluster Manager and selcet your CSV volume in Storage - Disks, then select "Remove from Cluster Shared Volumes".

    Best Regards,
    Ian
