rx26x0 disk slot SCSI IDs

Hi,

Quick question. I've got 3 rx26x0 systems (1 rx2600, 2 rx2620). None of them have a drive in slot #3 (i.e., each system has DKA0: and DKA100:). (Or is that slot #2? Is it 0-based?)

What will I see as the device ID when I insert a disk drive in the 3rd slot? I know it's going to be a "B" bus, and I'm guessing DKB0, but would like to know for sure.

Unfortunately, my systems are about 1400 miles away from me, and I'm trying to write a planning document. All the docu I've searched on HP's site does not specify what this slot is ID'd as; my own examination of the systems reveals that the second SCSI LVD controller is indeed PKB.

TIA,
Aaron

Aaron,

I vote for DKB0:

Based on the picture in:

http://h18000.www1.hp.com/products/quickspecs/12141_div/12141_div.HTML

and the following sentence:

Dual channel Ultra320 SCSI controller, 2 internal disks on one channel, 1 internal disk on a second channel

The SCSI adapter is PKB0, so the disk must be DKB0:

Hi Volker,

Yeah, I saw that pic and that statement. But voting is what the engineers do prior to implementation... ;^) They COULD have just as easily decided that DKB200 would be unambiguous and a good choice...

Nice try!

I see DKB200 on my RX2600 when I have 3 drives in it.

Wow, and that was just a WAG on my part! Lucky guess -- now I've got to go back and correct my docu, where I'd presumed DKB0!

Thanks, Richard!

Every three-slot rx2600 and rx2620 I've encountered has its bottom slot (as oriented when rack-mounted) as dbk200 dka0:, dka100:, dkb200:.

Also be aware that the connector on the back is DKB as well, so avoid ID2 for any devices you connect to that bus.

Aaron,

and once you know the 'answer', it's easy to find references by googling for 'rx2600 DKB200', like Colin's presentation:
