PH57208: ANTP0004E SEC SSID MISMATCH ON CESTPATH AFTER DISK SUBSYSTEM REPLACEMENT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After replacement of a GM disk subsystem, an attempt to
  establish paths to the new disk subsystem fails with a ANTP0004E
  message indicating an SSID mismatch. This is caused by the old
  disk subsystem World Wide Node Name (WWNN) being used by GDPS
  for the new disk subsystem.
  

Local fix

• Recycle the Kg and/or Kr NetView depending on if it is a primary
  disk subsystem (the Kg), secondary disk subsystem (the Kr) or
  X-disk disk subsystem (the Kr) and then do a GDPS DASD config.
  In an MGM 4-site environment this must also be done on the Kg/Kr
  pair handling the reverse direction (note that Kg and Kr are in
  this case the reverse of the active direction).

  ****************************************************************
  A query to find the World Wide Node Name (WWNN) of a storage
  subsystem during GDPS DASD configuration may use stale data and
  receive outdated/invalid information. An example is when
  a disk subsystem is replaced, and the same utility device is
  reused. The old storage subsystem WWNN will then be used instead
  of the correct one. Subsequent attempts to establish a PPRC path
  will then use the incorrect WWNN and fail.
  

Problem conclusion

• This PTF corrects the reported problems.
  
  MULTIPLE SYSTEM CONSIDERATIONS:
  
  The PTF must be installed on both Kg and Kr systems for the fix
  to be fully effective.
  
  RECOMMENDED ACTIONS
  
  A DASD config is needed if the "incorrect WWNN" problem has not
  been corrected prior to applying the PTF. For an MGM 4-site
  environment this can be done individually per Kg/Kr pair once
  the PTF is applied to both.
