how to distinguish whether a server is IA or PA-RISC architecture

James.Z — Thu, 24 Dec 2009 03:57:29 GMT

dear all,

is there any command or method to distinguish whether a HP-UX server is PA-RISC or Itanium architecture.

thanks

Hi James,

# model
9000/800/L3000-7x

9000 refers to PA-Risc

# model
ia64 hp server rx2620

ia refers to Itanium

Another hint..
If you are getting disk names with s1, s2, s3 in the end then it will be an Itanium server.

# lvlnboot -v
Boot: lvol1 on: /dev/dsk/c3t2d0s2
Root: lvol3 on: /dev/dsk/c3t2d0s2
Swap: lvol2 on: /dev/dsk/c3t2d0s2
Dump: lvol2 on: /dev/dsk/c3t2d0s2, 0

#ioscan -funC disk
disk 3 0/1/1/1.2.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
/dev/dsk/c3t2d0 /dev/dsk/c3t2d0s2 /dev/rdsk/c3t2d0 /dev/rdsk/c3t2d0s2

i have a shell script, in this script, i need to estimate whether the server is a PA-Risc or IA,
it executes different tasks for different architecture.

so i only need to use command 'model' to match ia64, if match, it's a Itanium, if not match, it a Pa-risc. am'i right?

Or "uname -m".

man uname

http://docs.hp.com/en/B2355-60130/uname.1.html

"[...] On Itanium(R)-based systems, this
option always displays ia64. [....]"

Hi,

I have seen some rare cases like model string changed manually to something else.

But still, I think model will be the best option.

>Sooraj: I think model will be the best option.

It is far easier to parse the output of Steven's "uname -m" than the zillions of model strings.
if [ $(uname -m) = ia64 ]; then

thanks

i'll choose the easiest one :).

Hi,

run model command , if model number starts with RP**** then it's PA-RISC if model number starts with RX**** or BL**** then it's IA

@Javed

# model
9000/800/L3000-7x

I guess older hardware might not give rp****
:)

Hi,

if i am correct L3000-7X is nothing but RP5470

>>> if i am correct L3000-7X is nothing but RP5470
Yes

>>> if model number starts with RP**** then it's PA-RISC
NOT in every case

As can be seen:
# model
9000/800/L3000-7x
Though the server L3000 (RP5470) is pa-risc but still "model" command does NOT say RP**** (in writing).

>>> i have a shell script, in this script, i need to estimate whether the server is a PA-Risc or IA
And when comes to scripting we should try to use a command which gives output as GENERAL as possible. "model" command starts with 9000 (this means it is pa-risc). This, I think is more general and better for scripting purpose.

And so do "uname -m".

All the above options are correct. We can use any one of them to identify type of model
