Any idea ?
Thanks

ioscan -fnCprocessor

mpsched -s

SAM -> Performance Monitors -> System Properties.

On newer HP-UX systems like 11.23 machinfo command will provide detailed information about your machine such as cpu, memory, firmware and os details.

hi ralf

either ioscan will list them or if you have STM installed then

# echo "selclass qualifier cpu;info;wait;infolog" | cstm

should do it

hi ralf,

try this:

# ioscan -fnC processor

or

# top
count the numbers from the CPU column

or

# sam
Performance Monitor -> System Properties -> see Active Processors

regards.

Hi Ralf,

since there could be a number of deactivated or ICAP CPUs, a simple ioscan or diagnostic output won't tell you about.

try

echo "sc product cpu;info;wait;il"|cstm

on a pa-risc system or

/usr/contrib/bin/machinfo

on itanium systems to get the number of installed cpus.
Look for "Processor state".

Also check "top".

Also

echo "processor_count/D" | adb /stand/vmunix /dev/kmem

NOTE /D is /d (lowercase) on itaniun systems

[Muthukumar_5]

Use the following methods:

a) top
b) ioscan -fnC processor
c) sam -> performance monitor -> system monitor -> processor
d) # echo "processor_count/D" | adb /stand/vmunix /dev/kmem

If you have machine with 11.23 then use machinfo.

Ignite-ux installed then, print_manifest
