Quantum DLT 80 ( DLT8000 ) in 5300 array slow


rp54xx, hpux 11.11, latest stape and other patches installed.

1MB/minute is all I can get out of this drive using a new tape ( tape is DLT IV p/n C5141F ).

Had f/w version V080, updated this to V089. No change in performance.

Anybody tackled this one recently??

Here's the HW info:

Re: Quantum DLT 80 ( DLT8000 ) in 5300 array slow

Hardware issues may cause the SCSI bus to downshift the speed - chack cable and terminator.

The drive may have a (mechanical) problem too - I would install LTT, run an assessment test and pull a support ticket. This will give you more information.

See

Hope this helps!

Torsten.
