PI73907: GDPS/ACTIVE-ACTIVE 1.7 ZDL FIX FOR MONITORING OF MTMM STATUS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• GDPS/A-A can incorrectly report the DASD mirroring status
  from GDPS/MTMM which could misinform the user when executing
  a ROUTING SWITCH for a workload running in a ZDL configuration.
  For example, a GDPS/MTMM mirroring status of FRZ might be
  reported as NOK (or vice versa). In either case, the switch
  would fail with the workload switch exception message GEO4573E
  and would be followed by message GEO4101E or GEO4106E.
