Learn how to extract CPU, core, socket details in HPUX. Get familiar with hardware related commands like print_manifest, machinfo, cstm, ioscan.
There are many times when one has to check CPU details of the server which are like the number of cores, sockets, etc. This detail is useful in capacity planning, troubleshooting, performance analysis, etc. There are many ways to get these details as below –
ioscancommand- cstm tool
print_manifestreportmachinfocommand- MP console
topcommand- SAR output
Before going into these methods make sure you check if logical CPUs are enabled on server or not. If yes then you need to take that into consideration while calculating the number of CPUs.
Let’s see the above methods one by one.
ioscan command
This is a well-known command to every HPUX server administrator. To scan or list hardware on the system, we use this command. Filtering processors out of this command give you details about CPU. This is helpful to get the only number of processors on the system.
# ioscan -kfnC processor

cstm tool
CSTM is another famous tool native to HPUX used to deal with hardware. This will give you in-depth details about each processor on the system. Type /usr/sbin/cstm and you will be on CSTM shell. Here type is below command :
cstm>selclass qualifier cpu;infolog

print_manifest report
This command comes bundled with the Ignite Ux package. If you have ignite installed on your server you will be able to run this command. This command shows a number of the processor along with its speed.
# print_manifest
NOTE: Could not read the /etc/resolv.conf file.
System Information
Your Hewlett-Packard computer has software installed and
configured as follows.
The system was created September 24, 2008, 02:30:54 EDT.
It was created with Ignite-UX revision C.6.10.97.

machinfo command
This command is available from HPUX 11.21 and above on RX models. This command gives you processor numbers, speed, sockets, and core details.
# machinfo
CPU info:
4 Intel(R) Itanium 2 9000 series processors (1.6 GHz, 12 MB)
533 MT/s bus, CPU version C2
6 logical processors
MP console
Login to MP console and enter the command menu by typing cm. Then ss is the command which shows processor status. This shows you processor sockets. So if you are seeing 8 CPU in top command and below output in MP then its 4 processor sockets housing 4 duel-core processors.

top command
This is the simplest way to check the number of CPU on HPUX as well as any Linux system. The top output shows your list of the processor at top of the page.

You can see CPU is numbered from 0 to 8 i.e. total of 8 CPU active.
sar output
Even sar output can be used to determine the number of CPU in the system. Use just one iteration for output for one second. sar will show one row for each cpu value.
Read our SAR tutorials
Counting the number of rows can help us figure out CPU count.
# sar -Mu 1 1

See first command actual output. We are stripping off extra 5 lines which are for total, headers to get exact count using awk. in second command. Even first output shows CPU numbering like top in first column!
