4000 DLT tape drive ....does anyone know how to set the jumpers?

I have been trying to attach a 4000 DLT tape drive to an hp server with an OS of 10.20.
Every time I attach the tape drive I loose my disks. I'm assuming this is a ID clash problem and I need to set the target id of the tape drive.

The tape drive has a panell on the back with numbers 1 - 12. Some of the switches are up and some are down. Does anyone know what they all mean? Which one's do I move to adjust the target id?

DLT 4000s has certain switch settings ( which are documented in the user guide ).
switches 2-7:
no emulation: 2,3,4,5,6, and 7 all off
HP-DAT : 4 and 5 on, the rest off
HP7980 : 3,4 and 5 on, the rest off
Exb-8500 : 2 and 4 on, the rest off

Remove existing device files, switch of the DLT, change the settings,power on the DLT, re-create device files.

While you are at it.......................

Before you boot your system, run ODE, then MAPPER. If you can't see your disks at this point then you have a problem with either your SCSI address or termination. Once you can see everything using MAPPER then proceed as directed by the previous poster.

In addition, the SCSI Id is set with switches 10-12. 10 being the most significant bit.

Thankyou all for your responses, they have been helpful. There are still 3 switches unaccounted for ...1, 8, 9. Do you know what they do?

All our manuals for the tape drive have disappeared into thin air!

Many Thanks

Hi Lorraine,

I'd be glad to forward the manual to you. I have a PDF format file but it's 5M. I need your email address.
