Has anyone come across snapshots that could not be mounted by snapdrive 4.2.1? I currently have a case open with support, but this is bugging the life out of me…

My current scenario is a windows 2003 sp2 server with 2 LUN’s, one for a scientific application called waters empower (D:) and the other for the oracle database that is associated with it (E:). A backup script of the scientific application runs nightly and calls a script that creates a snapshot while the database is in hot backup mode. All of this seems fine and dandy until I try to mount the snapshot to backup the contents to tape.

Using sdcli I should be able to execute the following command via a script to mount the snapshot in preparation for writing it to tape: sdcli snap mount –k d -s snap0 –d y

I have done some testing in which I tried to mount these snapshots from a remote server running snapdrive 4.2.1 as well and it was also unsuccessful. I also created a separate lun in which I took some snapshots of and I was able to mount it (this eliminates a problem with snapdrive on the machine and means to me that there is something happening to the snapshots that make them unmountable.)

What can I look for to see what is wrong with my snapshots? Snap list shows them to be normal…

Any thoughts would be appreciated.
