PI60536: INCRESYN SETGM MAY NOT ENABLE IR IN 4-SITE GDPS/MGM SYSTEM 16/04/09 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This problem occurs after installing PI37039/UI33308.  When
  running in an MGM 4-site configuration, a DASD INCRESYN SETGM
  may give rc=0 but fail to enable incremental resynchronization
  for devices that are part of the GDPS/GM configuration.
  
  The DASD INCRESYN SETGM will exhibit this error when run in one
  region but will work correctly when run in the other region.
  The region affected depends on the order of Partner statements
  in the GEOGROUP definition.
  
  ADDITIONAL SYMPTOMS:
  - GEOTRC message from VPCETAKE indicating "Contacting Kg" at
  the wrong region's Kg domain.
  - GEOTRC messages from VPCEACTA indicating that INCSET for a
  device has been bypassed because the secondary is "not in
  GDPS/GM configuration".
  
  - Subsequent monitoring gives message GEO687E DEVICE(S) HAVE
  INVALID PPRC SYNC RELATIONSHIP
  

Local fix

• Change the order of Partner statements in the GEOGROUP
  definition so that the Kg of the current Local region appears
  prior to the Kg of the current Remote region. Then recycle
  Netview in the Local region's master Kp system, after first
  ensuring there are no scripts active in any region.

Problem conclusion

• DASD INCRESYN SETGM processing updated to select the correct Kg
  system for GDPS/GM configuration retrieval.
  MULTIPLE SYSTEM CONSIDERATIONS
  To be immediately effective, this fix need be installed only
  on the Kp system that is executing the failing script.
  Eventually, the fix should be installed on the other Kp systems
  in both regions.
