IJ37747: HEALTH MONITORING IS RAISING AN ILL_UNBALANCED_FS DEGRADED HEALTH EVENT WHEN ADDING NEW DISKS TO A FILES YSTEM

APAR status

• Closed as program error.

Error description

• When adding a new disk to a file system, health monitoring will
  raise an ill_unbalanced_fs degraded health event as the file
  system will be unbalanced.  This degraded health event does not
  reflect the current recommendation
  of when to use the mmrestripefs
  command, and so the degraded health event's severity is to sever
  and is being changed from a degraded severity level to being a
  TIP severity level.
  

Local fix

• The ill_unbalanced_fs event can be added to the "ignore events"
  list in the mmsysmonitor.conf file. After mmsysmon is restarted,
  this event will be ignored by mmhealth and will not cause any
  unbalanced file systems to show as being degraded.

  Benefits of the solution:
  By changing the health event to a TIP,  the file system will
  no longer appear to be degraded.  A TIP (suggestion)
  event will be shown instead, and this TIP event is able to
  be hidden so that it will no longer show up in the mmhealth
  display.
  
  Work around:
  The ill_unbalanced_fs event can be added to the "ignore events"
  list in the mmsysmonitor.conf file. After mmsysmon is restarted,
  this event will be ignored by mmhealth and will not cause any
  unbalanced file systems to show as being degraded.
  
  Problem trigger:
  Adding a new disk to an existing file system.
