IJ45671: HA APPLICATION MONITORING SUSPEND/RESUME NOT HANDLED CORRECTLY

APAR status

• Closed as program error.

Error description

• The PowerHA cluster manager is supposed to reject changes
  to the application monitor function unless the cluster
  state is ST_STABLE. However, if the cluster is in a state
  such as ST_RP_FAILED and an attempt is made to suspend
  application monitoring, the application state will be
  changed to "ONLINE MONITOR SUSPENDED", but the
  application
  monitor(s) will not be suspended.
  This application state prevents either suspend or resume
  of application monitoring, even after the cluster state
  has been returned to ST_STABLE.
  

Local fix

• Check to make sure that the cluster manager is in state
  ST_STABLE on all nodes before attempting to suspend or
  resume application monitoring.   However, once the
  mismatched state has occurred, this can be corrected
  only by stopping and restarting PowerHA cluster services
  on that node.
  

Problem summary

• If user trying to suspend or resume the application when the
  cluster is not ST_STABLE state below message is seen in the
  clstrmgr.debug file even though suspend is failed
  Resource::setState: Resource APP_CON is already 6, return
  

Problem conclusion

• Using the clmgr manage suspend/resume application command from
  the smit to prevent application suspend or resume if cluster is
  not in ST_STABLE state.
  

Temporary fix
