UNIX for Dummies Questions & Answers

We are using HP unix how to find out how many number of CPU's in the system.

Have your tried mpstat ? which works in unix not sure about HP unix

We tried but its not working.We tried parstatus too.But its not working.

uname -a
HP-UX hydcpub B.11.23 U ia64 0688858991 unlimited-user license.

One way:
ioscan -C processor

But please don't post technical questions in "Post Here to Contact Site Administrators and Moderators". Like the description says: "Make Suggestions About Forums, Features, or Content here. Discuss Rules and Guidelines. Get Forum Support Here. (Registered Users Only)" and that is not what you're trying to do. The HP-UX experts will general check the HP-UX forum and you probably would have gotten a quicker answer there.

what about ' top '

it displays the CPU utilization for all the CPU's

I got the same from "machinfo"

machinfo on IA64

glance and top will tell you

ioscan | grep -i processor
# ioscan -fn | grep -i proc
processor 0 33 processor CLAIMED PROCESSOR Processor
processor 1 37 processor CLAIMED PROCESSOR Processor
processor 2 97 processor CLAIMED PROCESSOR Processor


This will work on 11i PA-RISC:

:
# Name:
# cpumem
#
# Purpose:
# List the CPU & memory particulars of a HP-UX 11i v1 server.
#
#@(#)cpumem.sh PR

nodename=$(uname -n)
model=$(model)
ncpu=$(echo processor_count/D |adb /stand/vmunix /dev/kmem |tail -n 1 |awk '{print $2}')
mhz=$(echo itick_per_tick/D |adb /stand/vmunix /dev/kmem |tail -n 1 |awk '{print $2/10000 " MHz"}')
mb=$(echo phys_mem_pages/D | adb /stand/vmunix /dev/kmem |tail -n 1 |awk '{print $2/256 " MB"}')

echo "$nodename $model ${ncpu} $mhz $mb"

# cpumem
ldgpdb01 9000/800/L3000-7x 3 750 MHz 12288 MB


(And no, I don't know why this box has three CPUs!)
