PH57428: Error in GDPS initialization or DASD config processing after renaming or removing a Group or Consistency Group

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Various errors may occur after the GDPS DASD configuration
  has been changed to remove or rename a Group or Consistency
  Group.
  
  The DASD Config process that makes the change may complete
  successfully. However, when DASD Config is next run, or
  when the first GDPS domain is initializing in the sysplex,
  GEO2675E DASD CONFIGURATION ERROR may be observed with
  incorrect indications like the following:
  
  - DSISVRT corrupted
  - site switch during the config validation phase
  - duplicate device
  
  Other unpredictable errors may occur as well.
  

Local fix

• Contact IBM GDPS support for assistance with checking for and
  removing residual global variable data the causes the problem.

  * PROBLEM DESCRIPTION: Error in GDPS initialization or DASD    *
  *                      config processing after renaming or     *
  *                      removing a Group or Consistency Group   *
  ****************************************************************
  When loading a DASD Config that removes or renames a Group
  or Consistency Group, GDPS does not properly remove the
  associated global variable information, which may remain in
  the NetView save/restore dataset (DSISVRT).
  
  Subsequent attempts to load the DASD Configuration from DSISVRT
  may access these residual definitions, which in turn may cause
  failures in GDPS initialization or DASD Config processing.
  

Problem conclusion

• This PTF corrects the reported problems.
  
  DASD Config processing is changed to clean up residual variables
  for Group or Consistency Group names that are removed from
  the configuration.
