Configuring for Microsoft Hyper-V

With IBM® Storage Support for Microsoft VSS and VDS, you can take shadow copies in a Microsoft Hyper-V guest OS.

If you installed the software iSCSI initiator on 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, IBM Storage Support for Microsoft VSS and VDS serves as a bridge to associate the FC HBA on the host to the guest OS when creating and deleting a shadow copy. IBM Storage Support for Microsoft VSS and VDS provider also supports the host iSCSI, depending on host and provider settings. Privileges to access the host Windows Management Instrumentation (WMI) are required to support this feature.

IBM Storage Support for Microsoft VSS and VDS cannot support the hardware information of a virtual hard disk (VHD). Therefore, IBM Storage Support for Microsoft VSS and VDS supports shadow copies only on pass-through disks on the guest OS. IBM Storage Support for Microsoft VSS and VDS automatically attaches the target LUN of the volume shadow copy to the guest OS as a pass-through disk.
