DY47682: DEVICE-SPECIFIC MIH VALUE (EXAMPLE: SIR MIH,181=10M) OVERRULES GENERAL MIH VALUE ONLY ONCE.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a device-specific MIH interval has been defined (for
  example SIR MIH,181=10M) and an interrupt becomes missing for
  this device, the operator msg
  AR+0013 0E04D P        DEVICE 181    LOST DEVICE END
  is issued after the device-specific MIH interval.
  If the interrupt continues to be missing, the device-specific
  MIH interval is not used anymore to trigger the next occurrence
  MSG0E04D. Instead, the overall MIH time interval (which is
  usually much lower) is used.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of SIR MIH command.                *
  ****************************************************************
  * PROBLEM DESCRIPTION: Incorrect logic when calculating a      *
  *                      device missing interrupt time and       *
  *                      comparing it with the device-specific   *
  *                      SIR MIH value.                          *

  * RECOMMENDATION: Apply APAR.                                  *

  usually much lower) is used.
  With the second (and all following) missing interrupt interval
  the device missing interrupt time was incorrectly calculated
  and compared with the device-specific SIR MIH,181=tt value.
  

Problem conclusion

• Incorrect logic for calculating the device missing interrupt
  time has been corrected.
