Media Patrol was started in Background Activity.


Failure Mode/Symptom:

When the host computer sends I/O to the disk array which has Media Patrol BGA running, the Media Patrol status will change to "Yield"



None. This is normal.


Additional Comments:

Yielding means that the Media Patrol BGA is waiting for I/O to finish. It is the policy of Media Patrol not to run (State set to YIELD) while I/Os are active on the controller. After host I/O is finished and idle for a period if time, Media Patrol BGA will continue.
