When backing up a Virtual Machine (VM) using the Agent for VMWare Virtual Infrastructure (AVVI) that has a RDM (Raw Device Mapping) or Independent disk attached to the VM and the RDM / Independent disk is excluded from the backup, the job will complete with the following exception:
V-79-57344-38721 - Failed to mount one or more virtual disk images:
Virtual Machine: Test Machine
Hard Drive 1: Disk 1.vmdk - Thin Provisioned Hard Disk 50GB NTFS volume
Hard Drive 2: Disk 2.vmdk - Thick Provisioned Hard Disk 400GB NTFS volume
Hard Drive 3: Raw Device Mapped to 1TB SAN LUN - Excluded from the backup
In this Example since hard drive 3 is a RDM device it will cause the backup to complete with the above exception. GRT selections will not be available for hard drives 1 and 2 because of this exception.
Symantec Backup Exec does not support GRT, Incremental or Differential AVVI backup of a VM having RDM or independent disk.
To backup VM having RDM/Independent disk install a Remote Agent on the virtual machine that has the RDM / Independent disk attached and back it up as if it were a physical machine.
