all I need is docs for this drive (specifically, SCSI ID jumper settings.

Where do you want to install it, in which type of machine/server?

I think what you have to do is scan the bus for the SCSI ids and then set the tape drive to an ID that is not being used.
I am trying to find you a link to the manual for that drive. The same drive is used in the TL891 Library.

Arno,
The DLT7000 is the same as TZ89 tape drive. I can't find specific documents regarding the internal SCSI id jumper settings on it online. Here is what I found, hope it helps

I'm kind of piecing a server together for a small office. I'm using a cheap SIIG AP-40 UW SCSI card with no other SCSI devices on the chain. This is what happens: when the tape drive's ID comes up during the bus scan it locks up. I was hoping that double-checking the ID/terminiation jumpers would solve the problem......

The internal DLT7000 is fast/wide single-ended (the library drive is HVD).

The drive should be physically the same as the HP branded DLT7000 drive, so you can look at the HP DLT internal drive manual for setting jumpers (i.e. SCSI ID, term power).

Note that the drive provides termination power, but it does NOT provide internal termination. You need to terminate the bus externally. You will need to use a single-ended (active) terminator, or a auto-sensing LVD/SE terminator.

> This is what happens: when the tape drive's ID comes up during the bus scan it locks up

Not having a terminator on the drive end, or having the wrong type may be what is causing the behavior you are seeing.

The HBA should also have termination enabled (both ends of the bus need to be terminated).
The journey IS the reward.
