active member of a virtual
disk family
An active member of a virtual disk family is a simulated disk drive created
by the controllers as storage for one or more hosts. An active member of a
virtual disk family is accessible by one or more hosts for normal storage. An
active virtual disk member and its snapshot, if one exists, constitute a virtual
disk family. An active member of a virtual disk family is the only necessary
member of a virtual disk family.
