{
{   The purpose of this request is to add a member volume to a set.  The set
{ must have already been created on the master volume by the STP$CREATE_SET
{ request (INITIALIZE_DEADSTART_DEVICE command), and this member volume must have
{ been initialized using the INITIALIZE_MS_VOLUME request.
{   The member can belong to no other set, and the
{ volume will remain a member of the set until a STP$REMOVE_MEMBER_VOL_FROM_SET
{ is issued or until the device is inactive at deadstart and a
{ stp$remove_inactive_members is issued.  The member volume may not already be
{ registered in the master volume of the set.
{   This request will cause both the member volume and
{ master volume to be activated, and the master volume will be updated to
{ reflect this new member.  This request can only be issued by the system
{ administrator, or volume owner.  The member volume owner must also own
{ the master volume.
{    If a member, as defined by its own member volume set table (on disk),
{ is already registered as a part of the set via a previous ADD_VOLUME_SET_SET,
{ but the member is not registered in the master volume (as a result of an
{ INITIALIZE_DEADSTART_DEVICE with the RECOVER_SYSTEM_SET_PARAMETER), the
{ master volume will be updated to reflect this member, and the member
{ volume will be updated to reflect the new unique identification of the
{ set, and the set master.  If the member is registered as part of the current set,
{ and the identification is recorded in the master, this request is unneeded and
{ an error status will be returned.  If the member volume is registered as a
{ member of another set (as indicated by external set name), an error status
{ will be returned.
