Cause



VSTOR2 drive is not available or started on the media server causing the failure in mounting disk images.


Solution



1. Check for the existence of <install_path>\system32\DRIVERS\vstor2-mntapi10-shared.sys

2. Run MSinfo32 and see under Software Environment | Signed Drivers if Vstor2 MintApi 1.0 Driver (Shared) is started and running
3. If you find the driver in the Drivers folder, try starting the driver using the following command in the command prompt.

net start vstor2-mntapi10-shared

4. If you do not find the driver in the drivers folder or it fails to start, it will have to reinstalled.
5. Browse to  Backup Exec installation directory: \VMware\VixDiskLib\bin\AMD64 and install the driver using vstor2-mntapi10-shared.inf
6. Check event viewer for confirmation of the installation and then check MSinfo32 to confirm if the driver is started and running.
7. Run backup job again and confirm if the GRT is available.

 

These steps will have to be confirmed on each server.

1. If you do find the driver and it shows \??\c:\windows.... then follow the link to the vmware site to remove the \??\

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2034124

2. After the \??\ has been removed then restart the server and run a backup job.
