Dual Process HP9000 A-Class

[Andy Parker_2]

Is it possible to dual process a HP9000 A-Class server with two PA-RISC 8600 CPU's, and run HP-UX11.23 on it ?.
Or is this a very silly question ?.

It depends on which A-class system you are talking about.

The A-400 is a single-CPU system. The A-500 can be a dual-CPU system.

The A-series machines (A400, A500 and rp24xx) are supported for HP-UX 11iV2 (11.23).

HP marketing imposed firmware limitations
on some rp24xx systems may prevent you
from successfully adding a second CPU.

For example, an rp2430 is limited by
marketing to 1 CPU and 2 GB RAM,
even though you could put a second CPU
and more RAM in it. (Which would make
it equivalent, IIRC, to an rp2470 ?)
By "limited" I mean that the machine
may refuse to bootup, possibly stopping
during POST. (I haven't tried it.)

Remember the HP Way? Marketing didn't :(

Thanks for your replies.

It's an HP9000 series A-500 (A5570B), I presume this means we could possibly do it.

I've searched the HP web site looking for instructions on how to add a second processor, but can't find anything.

Do you know if there is any documentation anywhere that explains how to go about it ?.

Hi,

You appear to have an rp2450 (based on
the part # you cited). I think I've seen
some manuals at docs.hp.com that discuss
adding hardware to such a machine,
but I can't recall where they were.

Andy,
Give this a shot:

I hope this helps.

Good Luck - Tim

On PA-RISC you can load only 11iv1 (11.11).

11.23 is meant for Itanium!!

TT,

No, that is not true anymore. With HP-UX 11.23PI you **CAN** run 11.23 on PA-RISC servers. This release is also known as HP-UX 11i V2 Sept. 2004. In the 11.23PI nomenclature the PI stands for PA-RISC/Itanium meaning it can run on BOTH.

Hi,
All A-series and 24-series support dual processor. For A400 and rp2430 you need to buy an upgrade option (software enablement key). The hardware for A400/500 and rp2430/2470 is identical.

Dear Patric,

Thanks for that update. I was just reading the same from software.hp.com

Anyway thanks for correcting me!

Now can we say PA-RISC & Itanium are fully binary compatible? (same code)
