IJ51909: SOME ADDITIONAL CCR MESSAGES MAY APPEAR IN MMFS.LOG

APAR status

• Closed as program error.

Error description

• There are a few occasions where error code 809 may be used
  inside the CCR Quorum management component. Although not user
  actionable, the product was changed to make some note of this in
  mmfs.log instead of, as had been the case, only available in
  GPFS Trace. The intent is to improved RAS in certain situations.
  

Local fix

• Use "mmlsmgr" before running "mmchnode --nonquorum" to determine
  the current cluster manager. If the node to be changed is the
  current cluster manager, then use mmlsmgr to determine the new
  cluster manager and then, if necessary, run mmchmgr to make an
  explicit choice of cluster manager.

  Benefits of the solution:
  Allows more likelihood of certain problem determination without
  requiring trace enablement.
  
  Work around:
  Use "mmlsmgr" before running "mmchnode --nonquorum" to determine
  the current cluster manager. If the node to be changed is the
  current cluster manager, then use mmlsmgr to determine the new
  cluster manager and then, if necessary, run mmchmgr to make an
  explicit choice of cluster manager.
