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 –
ioscan
commandprint_manifest
reportmachinfo
commandtop
commandBefore 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.
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 Class I H /W Path Driver S /W State H /W Type Description =================================================================== processor 0 128 processor CLAIMED PROCESSOR Processor processor 1 129 processor CLAIMED PROCESSOR Processor processor 2 136 processor CLAIMED PROCESSOR Processor processor 3 137 processor CLAIMED PROCESSOR Processor processor 4 144 processor CLAIMED PROCESSOR Processor processor 5 145 processor CLAIMED PROCESSOR Processor processor 6 152 processor CLAIMED PROCESSOR Processor processor 7 153 processor CLAIMED PROCESSOR Processor # ioscan -kfnC processor | grep processor|wc -l 8 |
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 :

I showed only one processor details above.
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.

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 |
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.

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.
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.
Counting the number of rows can help us figure out CPU count.
# sar -Mu 1 1 HP-UX apcrss78 B.11.11 U 9000 /800 11 /25/16 14:41:14 cpu %usr %sys %wio %idle 14:41:15 0 0 0 0 99 1 0 1 0 98 2 0 0 0 99 3 0 0 0 99 4 0 0 0 99 5 0 0 0 99 6 24 1 0 75 7 0 1 0 98 system 3 1 0 96 # sar -Mu 1 1 | awk 'END {print NR-5}' 8 |
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!
