OA26081: MSGARC6083A DURING ABACKUP OF MULTI-VOLUME USER TAPE DATASETS

APAR status

• Closed as fixed if next.

Error description

• MsgARC6083A issued continuously on regular intervals when
  DFSMShsm DFHSM ABARS ABACKUP processing is attempting to backup
  multiple multi-volume multi-file user tape data sets.  The
  msgARC6083A gets issued when the ABACKUP cannot allocate a
  volume on which the user tape data set resides.  In this
  instance, this is occurring because either a previous ABACKUP
  command or the currently processing ABACKUP command already has
  the dataset and volume allocated.
       While the ABACKUP is processing the multi-volume user tape
  data sets, it is leaving a trail of data sets enqueued SYSDSN
  SHR and volumes enqueued on SYSZVOLS EXCLusive.  If one of the
  volumes that already has a SYSZVOLS EXCL enqueue is called for
  later in the same ABACKUP or in a subsequent ABACKUP that
  reuses the same address space, the ARC6083A message is issued
  asking for the volume and asking the end user to respond WAIT
  or CANCEL.  If the response is WAIT, ABARS will wait 15 minutes
  while retrying the allocation every 15 seconds. This will
  continue until the address space is cancelled or the user
  responds CANCEL to the message.
  

Local fix

• There is no local fix for this problem. The client can mitigate
  the problem by having fewer multi-volume multi-file user tape
  data sets in their INCLUDE list. Also, they may be able to
  reduce the probability of this occurring because an ABACKUP is
  reusing an address space by increasing the number of ABARS
  address spaces via the SETSYS MAXABARSADDRESSSPACE command
