V2600 scsi adapter LVD or HVD differential scsi? and how find part# for an installed card?

[Steve Post]

When I run ioscan I see my scsi adaptor cards as: "SCSI C875 Fast Wide Differential."

1. Is the "Differential" here is High Voltage or Low Voltage? How can I tell?

2. If I had the part number of the scsi card, I would search on it in the HP site. "SCSI C857 Fast Wide Differential" doesn't sound much like a part number. I don't want take a screwdriver to the V2600 just to read off a part #. Is there a way for me to know the part number in PCI bus slot 0/0/0 without use of a blow-torch, sledge hammer, or crowbar?

Steve,

You can drill down via stm (or cstm) and get the card number

When I say card number, I mean 0/0/0. I already have that. I'm not looking for that.

I'm looking for something like A12345A. It should be printed on the card. I'm not opening or shutting it down for this number. People are using the box.

I'm looking for this elusive number because I don't know if "Fast Wide Differential SCSI is HIGH or LOW voltage "Fast Wide Differential SCSI".

That's my REAL question. I'm hoping that if I had the part number, I could search on THAT.

Hi Steve,

Path 0/0/0 is always the "built-in" card path in almost every server including the V-class.
In the V this is also the HBA that the tape drive is hung off.
Look at the PCI cages & the card that has a external SCSI connection that runs a ribbon cable back into the enclosure is the SCSI HBA at address 0/0/0.

HTH,
Jeff

[Jeff Schussele]

Oh & as far as I know it's an LVD HBA.

Steve,

I just went into STM

I highlighted the device

and did a current device status

This showed me the card part number

Jeff,
I'm almost positive it is HVA, not LVA. I'm just trying to confirm it.

DCE,
You must have a later version of stm (cstm, mstm). My version is A.44.00 B4708AA. I don't have that ability though. (it would've been nice).

Jeff,
I don't need to know where 0/0/0 is. I don't want to open the box. I want to know if there is a command from the unix prompt to give the part number of the scsi adapter that is sitting at 0/0/0. This question also applies to 1/0/0, 5/1/0, 3/2/0, 3/0/0, 7/2/0, 6/0/0, etc etc etc

Hi Steve,

HBA = Host Bus Adapter
Not High Voltage Adapter
Although I can't find the info in the HW manuals, I still believe it's a low voltage differential - but I could be wrong.

Cheers,

Hi Steve,

as far as I know "fast wide differential" is always high voltage in a HP9000.

Please run "information" on item "system" within "mstm/xstm", this should give you the part# even on a v-class.

[Steve Post]

Ok. I give.

The part number is _____.
It's staying that way because my version of stm does NOT tell me the part number. But it should. I understand that.

The part is either high or low voltage...still.

HBA is, and has always been HOST bus adaptor, and not high bus adaptor. I've known that too.

I understand you folks are in fact trying to help me. I DO appreciate that. Really.

So here are my two revised questions:
1. Besides stm (ahem...) or shutting down the box, is there a way to get the HP part number for a card on a HP9000 computer?

2. Is "SCSI C875 Fast Wide Differential" high or low voltage differential. I have 1 for vote for high, and 1 vote for low.

I forgot so say this is hpux11.0.

Steve,

I am running stm A.47.00

On an off chance I also looked at the print_manifest command (available in Ignite - /opt/ignite/bin/print_manifest)

It does list some part numbers, but not all. You might give it a shot.

Dave

[Jeff Schussele]

Well...it looks like it bolis down to just which board this is.
I see the following in PartSurfer:

A4800-69002 - which can be any of the following:
A3725A
A5073A
A5074A
A5081A
These are all probably HVD, but are not listed as HVD or LVD - just Ultra-wide Differential

But there is also the following
A5149A
Which is an LVD device - specifically stated as an Ultra2 LVD. And I *think* this is the standard "built-in" HBA for the V-class.

All the above have 68-pin I/Fs - both internal & external.

HTH,
Jeff

[Steve Post]

thanks.
That's a good idea about ignite.
Unfortunately it only told me "SCSI C875 Fast Wide Differential". Again.

And those card numbers are the type I'm looking for.

I'm just going to call HP support on it.
I'll put the answer here when I get it.

Once again, thanks for the effort.

Hi Steve,

if there are devices connected to the HBAs, please provide an ioscan -fn output, so we may conclude SCSI type.

[Mahesh Kumar Malik]

Hi Steve

1. LVD SCSI connector is high density type (small size) and HVD differntial is 68 pin connector (similar to parrallel port but bigger than it)

2. cstm or mstm will provide complete details on card product no

Regards
Mahesh

[Steve Post]

1. High or Low voltage?
Answer: HIGH voltage.

2. Part number is found how?
NOT via ioscan
NOT via stm
NOT via xstm, cstm, mstm
NOT tea leaves, or any pychic mumbo-jumbo.

I pulled off the big plastic panel and READ the part number off the exposed part of the card. It is A4800A. This is a HIGH voltage differential scsi card.

[Bill Colley]

Steve,

I am getting into this late.

There are two scsi cards for the V-Class system. A4800A which is a HVD and is supported in the V2200/2250 and the V2500/2600 series systems and the A5149A which is the LVD and is supported in the V2500/2600 series only.
There are no built-in scsi HBAs in the V-Class systems. All scsi devices are run off scsi HBAs in one of the io cardcages.
The card you are talking about should be the A4800A HVD HBA installed in the back half of the IOLF card cage.
Hope this info is usefull.

2. Is "SCSI C875 Fast Wide Differential" high or low voltage differential. I have 1 for vote for high, and 1 vote for low.


-> HIGH voltage differential.

[Steve Post]

game over.
the question is answered.
