Universal way to find out number of CPU's

Banibrata Dutta_1 — Wed, 06 Oct 2004 03:33:06 GMT

that are configured in the host, and that are physically present but not configured!!

thanks,

Hi,

I don't have a server to test it (mine are running with all cpu's configured) but you could try with

# ioscan -fncprocessor
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
processor 0 160 processor CLAIMED PROCESSOR Processor
processor 1 166 processor CLAIMED PROCESSOR Processor

Robert-Jan

hi robert:

on my host "ioscan -fncprocessor", gives --
ioscan: illegal option -- c
ioscan: illegal option -- p
ioscan: illegal option -- r
ioscan: illegal option -- o
ioscan: illegal option -- c
ioscan: illegal option -- e
ioscan: illegal option -- s
ioscan: illegal option -- s
ioscan: illegal option -- o
ioscan: illegal option -- r

although uname -a returns the following:-

HP-UX ochpt17 B.11.11 U 9000/800 548301562 unlimited-user license

thanks,
bdutta

Hi
Robert-Jan is right, with ioscan you can see number of CPUs, which work on your machine.
You can't see "hidden" CPU (not activated), e.g on rp34xx.

ioscan -fnC processor, Robery just missed the space :)

Re: Universal way to find out number of CPU's

Fred Ruffet — Wed, 06 Oct 2004 03:57:15 GMT

C option is uppercase :

>ioscan -fkn -C processor
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
processor 0 160 processor CLAIMED PROCESSOR Processor
processor 1 162 processor CLAIMED PROCESSOR Processor
processor 2 164 processor CLAIMED PROCESSOR Processor
processor 3 166 processor CLAIMED PROCESSOR Processor

issuing "ioscan -fkn -C processor|tail +3|wc -l" will give you the count...

Regards,

Fred

Hi,

One more option addition to the above all

If diagnostics is installed then
You can try stm also.
The information will give you the required
details.

Hi,

#ioscan -fnC processor

Re: Universal way to find out number of CPU's

Muthukumar_5 — Wed, 06 Oct 2004 04:29:39 GMT

You can use mpsched -s to know system process count there.

see man mpsched

Robert-Jan Goossens — Wed, 06 Oct 2004 04:31:51 GMT

Sorry Bdutta,

Yes ioscan should have been with a capital C

# ioscan -fnCprocessor

If you have stm installed on your systems you also try

# echo "selclass qualifier cpu;infolog" | /usr/sbin/cstm | grep "CPU Module"

Best regards,
Robert-Jan

If you are talking about icod, then:

icod_stat -a

will show active cpus, and

icod_stat -i

will show inactive ones.

HGN — Wed, 06 Oct 2004 08:09:27 GMT

Hi

You can use

ioscan -fnC processor which will give you the details

Prashant Zanwar_4 — Wed, 06 Oct 2004 08:31:29 GMT

sar -M -u will also give you number of CPU's you are using.

top also gives you number of cpu's

ioscan -fnC processor gives you cpu's

sam also gives you number of cpu's in system properties.

There are many ways like this to find number of CPU's

Hope this helps
Thanks

Re: Universal way to find out number of CPU's

Prashant Zanwar_4 — Wed, 06 Oct 2004 08:49:40 GMT

Also /opt/ignite/bin/print_manifest gives you all the system information.

Hope this helps
Thanks

Bill Hassell — Wed, 06 Oct 2004 11:32:40 GMT

None of the commands (print_manifest, top, mpsched, sar, ioscan) will show unconfigured or disabled processors. I think the newer online diagnostics will show disabled or unconfigured processors, but otherwise, you'll only see the working CPUs.

Prashant Zanwar_4 — Wed, 06 Oct 2004 11:50:25 GMT

Yes I agree with bill..I am sorry if I mislead you somewhere..that was information about active/working processor..

Thanks
Prashant

Shine_5 — Wed, 06 Oct 2004 12:37:18 GMT

you could use:

#ioscan -fnkCprocessor | grep processor | wc -l

Also the top command could help you. type:
#top

and you will see the Cpu states with their number

As I said - with ICOD:

icod_stat - display instant Capacity on Demand (iCOD) processor
status, usage information, and system information

Run it by itself, gives some systme info as well as:

Total processors: 6
Active processors: 5
Inactive processors that can be activated: 1
Inactive processors that cannot be activated: 0
Deconfigured processors: 0
Requested active processors: 5

Hi bdutta,

I just checked a system with deconfigured CPUs & the STM suite will indeed show active & deconfigured CPUs as well as which CPU is the Monarch.
I was in xstm & selected System -> Tools -> Information -> Run
Version of OnLineDiag/STM was 11.11.14.14 & the system was an N4000-44

HTH,
Jeff

Re: Universal way to find out number of CPU's

Oops - sorry version of OnlineDiag / STM was 11.11.14.15
