I need your help --

First of all, I have two 16GB 80MB/S IBM SCSI hard drives (Type: DGHS) and an HP RAID adapter, plus the SCSI cable with built-in terminator. The two drives have adaptors on them, allowing the 80-pin RAID adaptor to connect with the 68-pin drives. Now for the questions:

- I need to know where to place the jumpers (do they need to match on the drives and the adaptors? 0 and 1, or 1 and 2? Auto Power-ON?)

- When my system boots up, the RAID adaptor is recognized, but the drives are not. So, the problem is with A) The jumpers, B) the 68 to 80-pin adaptors or C) the IBM drives.

This is all connected internally.

Any suggestions? I can provide more info on the hardware if necessary. I am planning on running SUSE Linux, but that shouldn't be an issue as my problem occurs at boot.

Your help is appreciated!

i think i've talked to you about this before! :o)
do you have more info on the jumpers on the adapters? '0 and 1 or 1 and 2' isn't that helpful, what are the numbers?
on the drives themself just need to jumper each one to a unique SCSI ID (and don't use 7!), and set them to spin up at poweron (with only two drives that's fine to do).
also there's another possible problem area, "d) raid controller configuration". a few controllers need a software or RAID BIOS configuration utility to tell them to re-scan the bus and pick up any new drives. i'd still bet it's the jumpers though.
let me know what the numbered jumpers are...

haha, yes, you have. you've helped a lot so far, but i seem to have gotten stuck again : (

as for the jumpers, there are two sets on each drive: one on the actual drive itself, and one on the adapter. anyways, the jumper options on the adapters read (from top to bottom) "LED - SYN - DLY - MTR - ID3 - ID2 - ID1 - ID0" and

the jumper options on the drives read (from left to right) "ID3 - ID2 - ID1 - ID0 - KEY - AUTOSTART - ACTIVE TERM - SP SYNC - LED - WRITE PROT - DEL START - OPT BLOCK - DIS TI SY - DIS PAR - DIS UN A - DIS F/W NEG -- TERM PWR EN (ONLY 50 and 60SE)".

Okay, now I've got the hard drives to boot at startup (the HDD LED lights up at boot, and then once again before the adapter fails to recognize them), but my HP NetRAID card won't recognize either drive in the array.

It seems that to get the drives to boot, I needed to A) use a jumper on one 80 to 68-pin card but not the other (I placed it on ID1) and B) make sure that the SCSI cable was connected properly (I read online that one drive needs to be plugged in next to the terminator, and one needs to be at the other end of the cable.... the empty SCSI connectors should all be in the middle).

I've set the jumpers on both drives (one is set to ID0 and the other ID1 - the one set to ID1 also has the 80 to 68-pin adapter set to ID1 - and both are set to auto power on), but to no avail. After a google search, it sounds as though many people have tried similar or nearly the same configuration as this (same 80 to 68-pin cards, same internal configuration, and one page even listed an HP NetRAID with two IBM SCSI drives), but no one talks about how they set it all up.

Perhaps I'm missing something obvious here.....

I hope you can help! : )

One last thing to mention here:

I might have found the obvious solution: I don't have a SCSI controller. Do I need one? If so, which type of one? How would I connect it to the RAID controller? Externally? I'm dying to get this over and done with, lol.

As for the RAID utility file, I found one online. I might just have to wait to get an IDE drive, put Linux on there, set up all this SCSI stuff once that is done and then format the IDE drive and finally put Linux on the SCSI drives like I've been trying to do for so long : )

However, let me know if I need a SCSI controller, and if so, which cables and all that kind of thing.

Thanks for your help!

And after all of that jabbering, I think I've just realised that I need an "SE" SCSI cable and not the "LVD" SCSI cable I've been using.
