Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• New Function - Require the XRC CONTROL data set to be a minimum
  of one cylinder in size and be on a cylinder boundary.
  
  The procedure to update an existing XRC CONTROL data set:
  
  1. Issue the XSUSPEND command with the TIMEOUT option to suspend
  the session if it is still active.
  2. If the session is coupled, issue the XCOUPLE command with the
  PURGE option to uncouple it.
  3. Make a backup copy of the old control data set.
  4. Delete the old control data set and allocate the new control
  data set with new space requirements.
  5. Restart the XRC session using the XSTART command with
  SESSIONTYPE(XRC).
  6. Perform resynchronization using the normal procedures for
  your installation.).
  7. F ANTAS000,LISTSESS ALL to verify the storage control
  sessions are available.
  
  WARNING: DO NOT SKIP THE XCOUPLE PURGE IN STEP 2.  IF IT IS
  SKIPPED THEN THE XSTART PROCESSING WILL XEND THE STORAGE
  CONTROL SESSION BECAUSE THE CONTROL DATASET IS EMPTY.
