NOTE: In some cases, conflicts may 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.
12 To register the snapshot virtual disk with the host operating system, run
the host-based hot_add utility.
