Creating a Subdisk (LUN Carving)
The V-Switch
supports a maximum
of 512 subdisks.
You can create one or more subdisks on a physical disk. The subdisks can
then be converted to simple volumes to be used for creating concatenated,
striped and mirrored virtual volumes. When you create a subdisk, only
the defined area is converted into a subdisk. You must individually
convert each disk area into a subdisk for the physical volume to be usable
by the Volume Manager.
