Hi,

One way to do it:

ioscan -fnC processor

Then you could try:
# dmesg|grep processor
160 processor
166 processor

And yet another way...

echo processor_count/D | adb -k /stand/vmunix /dev/kmem | tail -1 | awk '{print $2}'

Since dmesg is a circular buffer, the processor information may no longer be there, but you could do a similar search through the syslog:

# grep processor /var/adm/syslog/syslog.log
Jul 30 14:37:42 hpatcux9 vmunix: 120 processor
Jul 30 14:37:42 hpatcux9 vmunix: 121 processor
Jul 30 14:37:42 hpatcux9 vmunix: 122 processor
Jul 30 14:37:42 hpatcux9 vmunix: 123 processor

This shows my system is a 4-way system. One thing these commands doesn't take into account is "deactivated" CPUs. For this reason, I typically use crashinfo to get CPU information. On my server, crashinfo shows:

System Name : HP-UX
Node Name : hpatcux9
Model : server rx5670
HP-UX version : B.11.23
Number of CPU's : 4
Disabled CPU's : 0
CPU type : IA64 (999 Mhz)
CPU Architecture : IA-64 0
Load average : 0.07 0.02 0.01

I get the number of CPUs, the number of disabled CPUs, the type, architecture, and speed of the CPUs.
