Configuring Hyper-V

With Volume Shadow Copy Service and Virtual Disk Service, you can take shadow copies in the Hyper-V guest OS.

If you installed the software iSCSI initiator in the guest OS and you do not plan to use FC protocol or iSCSI protocol on the host, the configuration is the same as the physical host.

Because the guest OS does not support an FC HBA, Volume Shadow Copy Service and Virtual Disk Service serve as a bridge to associate the FC HBA on the host to the guest OS when creating and deleting a shadow copy. IBM® System Storage® Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service also supports the host iSCSI, depending on host and provider settings. Privileges to access the host WMI are required to support this feature.

IBM System Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service cannot support the hardware information of a virtual hard disk. Therefore, IBM System Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service supports shadow copies only on pass-through disks in the guest OS. The IBM System Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service automatically attaches the target LUN of the volume shadow copy to the guest OS as a pass-through disk.
