IC89591: ACCESSING RAID MIGHT CAUSE LATENCY AFTER A LONG PERIOD OF INACTIVITY.

APAR status

• Closed as program error.

Error description

• Accessing raid might cause latency after long period of
  
  inactivity.
  

Local fix

• Prevent long periods of raid inactivity by configuring
  frequent log or file access.
  

Problem summary

• Customers making use of RAID volume might observe noticeable
  delay when accessing RAID volume that is idle for a long period
  of time
  

Problem conclusion

• Fix is available in 5.0.0.6. For 4.0.1 and 4.0.2, please upgrade
  to 5.0.0.6, then do a boot switch (roll back) to the previous
  firmware level.
  
  This is required as the fix is to a low level upgrade to the
  RAID controller component that requires the 5.0.0 firmware to
  complete the update.   This fix will remain when the "boot
  switch" CLI or "Firmware Roll-Back" GUI is performed.
  
  Note:  the roll back will restore the appliance to the state at
  the time of the upgrade to the 5.0.0 firmware except for this
  fix.
