After creating one or more snapshot virtual disks, mount the source virtual disk, and restart the host application using that source virtual disk.

9In the AMW, select the Mappings tab, assign mappings between the snapshot virtual disk and the host that accesses the snapshot virtual disk.

NOTE: In some cases, conflicts might result from mapping the same host to both a source virtual disk and its associated snapshot virtual disk. This conflict depends on the host operating system and any virtual disk manager software in use.

10To register the snapshot virtual disk with the host operating system, run the host-based hot_add utility.

11To associate the mapping between the storage array name and the virtual disk name, run the host-based SMdevices utility.

NOTE: If your operating system requires additional instructions, you can find those instructions in your operating system documentation.
