50-pin or 68-pin ?

Hi all

THE BACKGROUND:
A Client has a racked G50 with a racked 20/40Gb drive attached

THE REQUIREMENT:
I want to daisy chain a DLT-7000 to the the existing Drive so I must provide the correct cable connection

THE QUESTION:
How do I find out if the 20/40Gb drive is 50-pin or 68-pin?

THE RESTRICTIONS
Can't look at the back of the device until next week, but need the answer today

Client claims an I/O scan doesn't give a clue

DOES THIS HELP?
The old HP support contract gives the part # for the 20/40gB device as TTZATA1
[PartSurfer & Google yield no results when I plug that code in]

Thank you!
Regards
Mike

The I/O scan WILL show you if its 50 or 68 pin.
eg;

ext_bus 2 10/8 c720 CLAIMED INTERFACE GSC add-on Fast/Wide SCSI Interface
target 17 10/8.2 tgt CLAIMED DEVICE
tape 4 10/8.2.0 stape CLAIMED DEVICE Quantum DLT4000

You can see from this the Quantum DLT4000 (20/40Gb) is on a Fast/Wise (68pin) SCSI bus.

Or a single ended DLT from ioscan looks like this;

xt_bus 7 10/16/8 scsi1 CLAIMED INTERFACE HP 28655A - SE SCSI ID=7
target 26 10/16/8.0 target CLAIMED DEVICE
tape 1 10/16/8.0.0 tape2 CLAIMED DEVICE HP 7980S

As you can see the scsi controller listed before the DLT drive (a TTI 20/40Gb DLT) is SE SCSI (50 pin).

oops sorry, you used the partsurfer I guess!

If you have visio, you can use this to get stencils and then ask the client to describe the back of the machine, or digitally take a picture of it!

Hello,

I guess the racked 20/40Gb drive is a DLT4000 drive. But what type of DLT4000 drive is it? Shouldn't be 68 pin, that's for sure. Should be 50 pin. Some older drives had the centronics port though, so beware.

As a rule... SCSI SE = 50 pin. DLT7000 is SCSI-2 SE. If I remember correctly, that should be 68-pin.

HTH,
Vince

Mike,

I'm not a pharoah or a maltese king, but I have worked on DLT4000s and DLT7000s.

(that is NOT, incidentally, intended to be disparaging in any way...you guys are the greatest!)

The problem you are going to run into is that the DLT4000 is a single-ended SCSI device and the DLT7000 is a Fast-Wide Differential SCSI device. The two will not work on the same bus, unless a single-ended - to - differential converter is employed. You would not want to do that in any event, as a DLT7000 will saturate an HP-PB FWD SCSI interface when it streams data. (You could get away with other FWD SCSI devices on the bus with a DLT7000, as long as you could ensure that they weren't tansferring data concurrently with the DLT7000, but it's not a good idea.)

If you're going to install a DLT7000 drive on a G50, you're going to want to want to attach it to a FWD SCSI card by itself, if at all possible. The FWD SCSI interface for the NOVA class systems is a 28696A. This ID should be visible in the output of an ioscan -fn command.

I hope this helps.

Best Regards,

Dave
