After creating one or more snapshot virtual disks, mount the source virtual
disk, and restart the host application using that source virtual disk.
9 In 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.
10 To register the snapshot virtual disk with the host operating system, run
the host-based hot_add utility.
11 To 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.
