Taking snapshots using Hyper-V

You need to configure LUNs with the same size as source LUNs as snapshot target in the free pool on storage.

Before taking a snapshot for the volume on the guest OS, type the following command to check if the configuration is correct.

Note: The command supports one or more drive letters or mount points. In the example command, X: is the driver letter or mount point to take the snapshot. ibmvcfg testsnapshot X:

The procedures to take, delete, mask, resynchronize and import snapshots are the same as the procedures for the physical host. Provider attaches the target LUNs to the physical host and then assigns it to the guest OS as a pass-through disk when taking or importing a snapshot. When deleting or masking a snapshot, IBM® VSS Hardware Provider removes the target LUN from the guest OS before detaching it from the physical host.

See Snapshots with NPIV for information on these tasks.
