Hi all,
issuing an
echo "scsi add-single-device 0 1 2 3" >/proc/scsi/scsi
works fine but you'll lose any tagged command queueing (TCQ) depths > 1.
They'll be reset to one with (I'm sure) some performance penalty for the
devices supporting it. This is why I don't use it anymore, my IBM scsi
disks appear to be faster with a queue depth of eight.
-> I could not find the reason for this by looking at the source code, but
I must admit I didn't tried too hard...
-> Maybe one day this useful command will be out of BETA and no longer have
this side effect on the TCQ queue depth.
Thanks.
Mit freundlichen Gruessen / best regards
