IT34757: MQ Appliance status command may not correctly report failure states if there is an HA failure on both HA appliances

APAR status

• Closed as program error.

Error description

• In some situations an MQ appliance operating in an HA group
  could report an incorrect status when there are failures on both
  nodes. In this case, the "status <qmgr>" command may report "HA
  Status: Normal", when the status is in fact "HA Status: Resource
  Failed".
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Those using MQ Appliance configured with the High Availability
  (HA) features.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The fix for APAR 'IT29783: Querying queue manager status may
  cause performance overheads on MQ appliance' introduced a
  possible problem in HA operation where an incorrect status could
  be reported if there are failures on both nodes.
  
  This issue was seen when the first appliance encountered a
  low-severity failure, which would normally be handled internally
  and not reported to the user, before the second appliance
  encountered a severe failure, which should change the reported
  status. A logic error meant that the low-severity failure
  suppressed reporting of subsequent failures.
  

Problem conclusion

• The code has been modified to correctly report the status when
  there are failures on both MQ appliance nodes.
