V-79-57344-38277 - Unable to open a disk of the virtual machine.
Good afternoon,
I am having an issue with Symantec Backup Exec 2010 R2 trying to backup a VMware cluster using the SAN method. There are two custers, the first cluster works fine and the SAN storage is Equallogic. The second cluster is a MD3000 SAN with a Microsoft server that the hosts point to for iSCSI connections. This is the one that I am having issues with.
When I run the backup job, it creates the VMware snapshot, then deletes the snapshot and the job fails with:
Backup- VMVCB::\\vcenter-server\VC
VixDiskLib_Open() reported the error: You do not have access rights to this file
V-79-57344-38277 - Unable to open a disk of the virtual machine.
VixDiskLib_Open() reported the error: You do not have access rights to this file
I reviewed the debug log and unfortunately becuase there were 3 other backup jobs going on at the same time, it was a little difficult to find the section dealing with this error but I beleive I found it:
BEREMOTE: [05/19/11 13:12:28] [5280] [fsys\shared] - VDDK-Log: SAN: Cannot access a SAN/iSCSI LUN backing this virtual disk. (Hint: If you are using vcbMounter you can use the option "-m nbd" to switch to network based disk access if this is what you want.) If you were attempting file-level access, stop the vmount Service by typing "net stop vmount2" on a command prompt to force vmount to re-scan for SAN LUNs and re-try the command.

can you snapshot this machine manually from the take snapshot gui?

The solution was that the current configuration of the MD3000 (not i) SAN is not supported by VMware and i believe that is why backing up using the SAN method would not function. To backup these VM's, we had to use the NBD method.
