Configuring source volumes

Because the Volume Shadow Copy Service and Virtual Disk Service support taking shadow copies only for volumes that are based on disks from SAN Volume Controller or DS8000®, the disks must be assigned to the guest OS by the pass-through mode.

1. Shut down the guest OS and add the iSCSI Controller to the guest OS.
2. Create LUNs and map them to the host in the storage unit that is connected to the host.
3. Add the pass-through disk drive to the guest OS.

   Note: The guest OS can be in the running state, but the disks should be in the offline state on the host so that they can appear in the physical hard box combo box.

4. Log on to the guest OS.
5. Create a volume on the newly added hard disk.
6. Assign a drive letter or mount point to the volume.
