Your queue_depth value for tape devices looks to be too big (254) and
seems to be value for tagged devices. You can try to switch to
untagged command depth value (1) by:

echo 1 > /sys/bus/scsi/devices/2\:0\:8\:0/queue_depth

or

echo 0 > /sys/bus/scsi/devices/2\:0\:8\:0/queue_depth

I am not sure if the timeout=900 is not consequence of your
queue_depth. However the timeout is the same as time of your switching
tape drive in ONLINE state after tape load. So maybe worth to try.

Best regards.
