receive an I/O timeout when devices of higher priority keep
utilizing the bus.
The default setting for “Drive I/O Timeout” is 7 seconds. It is
highly recommended not to change this setting. Setting the timeout
to a lower value will cause the controller to judge a drive as failed
while a drive is still retrying, or while a drive is unable to arbitrate
the SCSI bus. Setting the timeout to a greater value will cause the
controller to keep waiting for a drive, and it may sometimes cause a
host timeout.
