Determining IA or PA

[yatin]

How can I determine which system i am using IA or PA from command line

[Elmar P. Kolkman]

uname -r is a way: for IA it will report something like B.11.22 or B.11.23, anything else should be PA_RISC.
Or use model, though I don't know what will be reported on IA systems.

use the uname command.
on IA:
-bash-2.05b$ uname -m
ia64
on PA:
bash-2.01$ uname -m
9000/800

uname -a

I should have been more specific:

11.11 system PA-RISC
uname -a
HP-UX serverX B.11.23 U ia64 12345678090 unlimited-user license

itanium
uname -a
HP-UX serverY B.11.11 U 9000/800 3284783283 unlimited-user license

and another

getconf MACHINE_MODEL
will give some additional info

hai,

We can get the machine type with uname -m command. But there is a regulation in usign uname with -m as,

----- man uname --
It is recommended that the model command or the getconf command be used to obtain the model name, since future model names may not be compatible with uname. See model(1) and getconf(1).

----------------
Using model command
===================
# model
IA> ia64 hp server rx2600

PA > 9000/800/A500-5X

Using getconf
=============
# getconf MACHINE_MODEL

We can know the machine model effectively.

Geez I got these back the front ....

itanium
# uname -a
HP-UX serverX B.11.23 U ia64 12345678090 unlimited-user license

11.11 system PA-RISC
# uname -a
HP-UX serverY B.11.11 U 9000/800 3284783283 unlimited-user license

and another

# getconf MACHINE_MODEL
ia64 hp server rx7620 (itanium)
9000/800/N4000-55 (PA-RISC)

hi,

following is not from my head, I red it few days ago here but I can't find it now:

getconf CPU_VERSION - give CPU version:

528-PA1.1,
532-PA2.0,
768-IA64 (aka Itanium, aka IPF)

info is taken from /usr/include/sys/unistd.h

fwiw, keying off of the release will work for _now_ but in the future, there will be a time when IA and PA systems run identically numbered OS releases, so going with the other ideas will have longer applicabiltiy.

[Tim Sanko]

getconf CPU-VERSION
uname -a
model

These three commands will provide you with the needed information.

I personally use the uname -a as the 11.11 and below are PA-RISC and the 11.22 and above are IA-64. There is supposed to be a merged version on the Horizon. Then you would use the command:model.

Hope that helps.
