SCSI question with pics

GM@N · 17 Oct 2007 at 16:59

I'll keep this simple as I can, I have 5 of these

1 of these Adaptec SCSI Card 29320LPE

The SCSI drives have this type of connector and the SCSI card is as the above picture. Can I connect these and if so what cable will I need?

Cheers.

i have a similar configuration in my file server, the card uses same port as on your card and drives use same connector as your drive, mine uses a backplate that all the drives connect to then a cable comes from the backplate to the card

Thanks for the reply can you tell me what backplate i will need?

SCA 80 to 68 Pin Adapter, da bay will have em

Would I need one of these for each drive and a regular SCA80 cable to go from the SCSI card to the Adaptor(s)?

Get a decent SCSI card while your at it!! You can buy Geniuen (sp?) brand new DUAL Channel Adaptec 39320 SCSI cards from the bay for £75

These babys are fast and normally retail for £280+ :eek:

Also are them drives native 80-Pin or is the caddy converting them from 68-PIN ???
The reason caddys normally use 80-pin is because the 80-pin SCSI connector also supplys the power too the drive unlike 68-pin SCSI which use's a seperate power connector like a normal HD.

I brought four SCA 80 to 68 Pin Adapters, but now I need some help connecting them. I'm not sure how I set the jumpers I set every drive with a different ID but when I boot none of the drives are detected it just times out when detecting.

On the adapters I have these jumpers

I have the jumpers set like this

Code:

           ID0  | ID1   | ID2  | ID3   | MTR   | DLY   | SYN   | LED

Drive 1    :      :       :      :       :       :        :       :

Drive 2    |      :       :      :       :       :        :       :

Drive 3    :      |       :      :       :       :        :       :

Drive 4    |      |       :      :       :       :        :       :

Hope that explains it.

Cheers

Is the cable the right type for the drives and properly terminated? In fact is the card the right type for the drives, ie they're not some wacky flavour of SCSI?

GM@N · 25 Oct 2007 at 19:46

This is the hardware being used.

SCSI card: Adaptec SCSI Card 29320LPE
Connector: One 68-pin Ultra320

SCSI Drive: HP Wide ULTRA320 SCSI 10K RPM U320 Universal Hard Drive
Connector: 80 pin Hot Swappable/ Pluggable

SCA 80 to 68 Pin Adapters

Startech 4 Drive U320 Terminated Internal SCSI Cable 68-pin

OK the card, drives and cables should all be compatible so in theory everything should work. Start with one drive on the last connector of the cable, set the ID to 0 and go from there. It'll probably be worthwhile trying to determine the ID of the card itself, normally it'll be 7 but check it anyway.

If i'm reading this right, you have Drive 2 and 4 set to ID0 and Drive 3 and 4 is also set to ID1 and drive 1 ID not set at all, the only drives jumper strapped correctly is drives 2 and 3 but both are going to clash with drive 4 as its set to 2 ids (wrong). Each drive must have its own ID.

rpstewart · 26 Oct 2007 at 07:19

The jumpers are fine, the 4 positions are binary digits to give you the possibility of 16 IDs (one of which will be used by the card though). Therefore in the diagram above Drive1=ID0, Drive2=ID1, Drive3=ID2 and Drive4=ID3.

Would try that way personally. Got no detection either with your previous combo and my adapters as well. I've seen adaptors which only support 4 IDs by jumper and don't use SCSI ID bits (really cheap ones, i got a few too

).
