{
{   The purpose of this request is to allow device management to notify
{ set management that a new disk volume has become active.  Set management can
{ then update the active set table, so that on future requests from
{ device management the status of the volumes
{ will be correct.  Device management must issue this request for all new
{ disk volumes that become active.  Set management will initially
{ turn around and ask device management if this volume has
{ a volume set table, and try to attach it.
{   If the volume is the first volume active in a set, the access status for
{ that set will be initialized to stc$deny_access.  This indicates that no
{ permanent file use of the set will be allowed until a
{ stp$change_access_to_set request is issued.
{   If a member volume becomes active and we are have re-initialized the
{ system device, we will attempt to re-add this member volume back into the
{ newly initialized master volume.

{
{ ACTIVE_VOL: (input) This parameter specifies the recorded vsn of
{       the volume that has just been activated or made available.
{
{ INTERNAL_VSN: (input) This parameter specifies the internal vsn of the
{       active_vol.
{
{ ACTIVE_VOLUME_TABLE_INDEX: (input) This parameter specifies an index
{       assigned by device management.  This is kept for device management
{       for efficiency reasons, and is not used by set management.
{
{ SET_NAME: (output) This parameter returns the set name
{       of the set that the volume belongs to.
{
{ STATUS: (output) This parameter returns the request status.
