Yanling,

Your reply makes sense.  So, the controller fails SCSI commands
with this sense key while it is transferring a volume.

Are the failed commands only for the volume that is being
transferred, or will it fail any command queued to that
controller while it is doing a transfer.

Now, on to figuring out why some of these requeued commands
fail the requeue.

Thanks!
Dave
