For backup of Hyper-V Virtual Machines (VM), the Microsoft Hyper-V VSS Writer is used to snap the volumes hosting the VHD files for the VM(s). During the GRT phase, these snapshots are mounted as a mount point on the host server to generate the catalog information for the backed up VM(s). By default Backup Exec creates the mount point on a volume that has the most free space. In some cases it is observed that the mount process fails if the volume being used to mount the snapshot is an ISCSI/SAN volume being managed by the Windows 2008 Failover Cluster.
Failed to mount one or more virtual disk images.
