Problem conclusion

Temporary fix

Comments

• Code has been changed to support HyperSwap IOTIMING triggers
  on GDPS/MTMM system, in a manner similar to the existing
  GDPS/PPRC IOTIMING support.
  
  In a GDPS/MTMM single leg configuration, GDPS evaluates
  counters, checks mirroring status, and queries secondary
  volumes to determine if a HyperSwap trigger message should
  be issued.
  
  In a GDPS/MTMM symmetric leg configuration, GDPS executes
  the same checks on the HyperSwap preferred leg to evaluate
  status. If the check fails, GDPS will automatically
  repeat the evaluation sequence on the alternate HyperSwap
  leg to issue the HyperSwap trigger message.
  See the GDPS/PPRC Installation and Customizaton Guide for
  additional information about IOTIMING, which is now  also
  applicable to GDPS/MTMM systems.
  
  PRODUCT ENHANCEMENT
  This PTF provides support for the IOTIMING HyperSwap trigger
  in GDPS/MTMM.
  
  RESTART NEEDED
  It is not necessary to IPL the system to activate the fix;
  a stop and restart of the GEOXCFST started task will suffice.
  However, since the GDPS SGDPLOAD library is included in the
  linklist, a F LLA,REFRESH must be performed after the fix is
  installed and prior to restarting GEOXCFST.
