Get the Processor Type on Solaris
It’s easy to get the type of processor that a Solaris box is running on. While this might seem like a silly thing to need to know, if you are connected into a Solaris server at a remote location, you may need to know what type of processor is being used in order to install the correct packages.
uname -p
The uname command gives information about the current system.
Example on an Intel box:
# uname -p
i.386
Example on an Sun Sparc box:
# uname -p
sparc

As part of script I’ve made to automatically get HW details of our servers (HP9000, Solaris, Fujitsu, AIX,…) this function give you information about processor number, type and speed:
function sunos_hw_CPU {
typeset num=$( psrinfo | wc -l )
typeset tipo=$(
prtconf -pvPD | egrep -e “device_type.*cpu|name” |
sed -n “/device_type/{n;p;}” | awk -F\’ ‘{ print $2 }’ |
sed -e “s/SUNW,//” | head -1
)
if [ "$tipo" == "cpu" ]
then
tipo=$(
prtconf -pvPD | egrep -e “device_type.*cpu|compatible” |
sed -n “/device_type/{n;p;}” | awk -F\’ ‘{ print $2 }’ |
sed -e “s/SUNW,//” | head -1
)
fi
typeset freq=$(
/usr/sbin/psrinfo -v| grep operate | sed -e “s/.*at //;s/,//” |
head -1
)
echo $num \”$tipo $freq\”
}
# sunos_hw_CPU
16 “UltraSPARC-IV 1350 MHz”
Enjoy it
!
Alex, thanks!
That’s a great script… I might convert it into linux…
As part of the same script, I’ve done this function for Linux (including VMware ESX servers):
function linux_hw_CPU {
typeset num=0
typeset name=”"
typeset cores=”"
name=”$(
cat /proc/cpuinfo | awk -F: ‘
/vendor_id/ { vendor=$2 }
/model name/ { model=$2 }
/cpu MHz/ {
if( model ~ “Hz” ) {speed=”"} else { speed=$2″ MHz” };
print vendor, model, speed; }
‘ | tail -1
)”
num=$(
if [ -r /proc/vmware/cpuinfo ]
then
awk ‘/pcpu/ { print NF-1 }’ /proc/vmware/cpuinfo
else
cat /proc/cpuinfo | grep processor| wc -l
fi
)
# ESX: mas info sobre logical/cores/packages
if [ -r /proc/vmware/sched/ncpus ]
then
cores=$( echo $( cat /proc/vmware/sched/ncpus ) )
fi
echo $num $( echo “$name ($cores)” | enclose )
}
For example, in one of our ESX box, I get:
32 “GenuineIntel Intel(R) Xeon(TM) CPU 3.00GHz (32 logical 16 cores 8 packages)”
(ESX is nice, it gives me information about chip, cores and also logical (that is because hyperthreading is activates on that box).
A normal linux server (not ESX) would give something more simple like:
2 “GenuineIntel Pentium III (Coppermine) 696.417 MHz ()”
Hope it helps
Alex : ¿ Its posible to get the complete set of scripts to identify the hw?..thanks in advance
What if you have a 64 bit dual core CPU and you are running a non SMP kernel , the script will show only 1 CPU.
Is there a way to get the details from hardware ?
On linux , dmidecode -s processor-version will give you the CPU count , however how to find out if its a single or multicore processor
@Keith: I believe that if you use a non-SMP kernel, your OS won’t be able to see more than 1 CPU, so you won’t be able to get more information about CPU, unless maybe you use vendor specific drivers.
If you use a SMP kernel, you may be able to get information about the number of chips and the number of cores of each cpu chip using /proc/cpuinfo. Look at how I actually decode it in my script:
function enclose {
tr -s ” ” | sed -e “s/^/\”/; s/$/\”/; s/\”\ /\”/; s/\ \”/\”/”
}
function linux_hw_CPU {
typeset num=0
typeset name=”"
typeset cores=”"
name=”$(
cat /proc/cpuinfo | awk -F: ‘
/vendor_id/ { vendor=$2 }
/model name/ { model=$2 }
/cpu MHz/ {
if( model ~ “Hz” ) {speed=”"} else { speed=$2″ MHz” };
print vendor, model, speed; }
‘ | tail -1
)”
num=$(
if [ -r /proc/vmware/cpuinfo ]
then
awk ‘/pcpu/ { print NF-1 }’ /proc/vmware/cpuinfo
else
cat /proc/cpuinfo | grep processor| wc -l
fi
)
if grep -q “physical id” /proc/cpuinfo || grep “siblings” /proc/cpuinfo
then
chip_count=$( grep “physical id” /proc/cpuinfo | sort -u | wc -l )
chip_core=$( grep “siblings” /proc/cpuinfo | tail -1 | cut -d: -f2 )
cores=”($chip_count chips x $chip_core cores)”
fi
# Blades HP con
if [ -x /sbin/hpasmcli ]
then
chip_name=$( /sbin/hpasmcli -s “SHOW SERVER” | grep “Name” | head -1 | cut -d: -f2 )
chip_speed=$( /sbin/hpasmcli -s “SHOW SERVER” | grep “Speed” | head -1 | cut -d: -f2 )
chip_core=$( /sbin/hpasmcli -s “SHOW SERVER” | grep “Core” | head -1 | cut -d: -f2 )
fi
# ESX: mas info sobre logical/cores/packages
if [ -r /proc/vmware/sched/ncpus ]
then
cores=”($( echo $( cat /proc/vmware/sched/ncpus ) ))”
fi
# Linux Itanium IA64
if grep -q -i itanium /proc/cpuinfo
then
name=”$(
grep “vendor” /proc/cpuinfo | cut -d: -f2- | tail -1 ) $(
grep “arch ” /proc/cpuinfo | cut -d: -f2- | tail -1 ) $(
grep “family” /proc/cpuinfo | cut -d: -f2- | tail -1 ) $(
grep “cpu MHz” /proc/cpuinfo | cut -d: -f2- | cut -d. -f1 | tail -1 ) Mhz”
chip_count=$( grep “physical id” /proc/cpuinfo | sort -u | wc -l )
chip_core=$( grep “siblings” /proc/cpuinfo | tail -1 | cut -d: -f2 )
cores=”($chip_count chips x $chip_core cores)”
fi
echo $num $( echo “$name $cores” | enclose )
}
linux_hw_CPU
For example:
# linux_hw_CPU
8 “GenuineIntel Intel(R) Xeon(R) CPU E5345 @ 2.33GHz (2 chips x 4 cores)”
Hello guys,
Thanks alot for your great work! Anyone managed to differentiate the number of socket/core/threads on Sun CMT processors?
Hi,
Physical disks on sun solaris : psrinfo -p
@Alex,
Great script. But if you have CPUs with different frequencies, then it will NOT work. For getting the Frequency, you’ve used the below command:
/usr/sbin/psrinfo -v| grep operate | sed -e “s/.*at //;s/,//” | head -1
This will result in:
$ /usr/sbin/psrinfo -v| grep operate | sed -e “s/.*at //;s/,//” | head -1
1200 MHz
However, when I check, I’ve got 8 CPUs – 4 with 1200 MHz and 4 others with 900 MHz
$ /usr/sbin/psrinfo -v| grep operate | sed -e “s/.*at //;s/,//”
1200 MHz
1200 MHz
1200 MHz
1200 MHz
900 MHz
900 MHz
900 MHz
900 MHz
You can perhaps use something like:
/usr/sbin/psrinfo -v| grep operate | sed -e “s/.*at //;s/,//” | uniq
or
/usr/sbin/psrinfo -v| grep operate | sed -e “s/.*at //;s/,//” | sort -u
using the above commands for frequency, I get the below output:
$ ./sunos_cpu_info
8 “UltraSPARC-III+ 1200 MHz 900 MHz”
Anyway, thanks a lot for your wonderful script (for both Linux & Solaris!)
@ Alex, I’m referring to your first post!
Really usefull scripts for Linux and Solaris.
I have been trying to determine the number of cores in a system with Sparc T2 cpus.
These cpus hav 4,6 or 8 cores per cpu
psrinfo -pv | wc -l will return 32, this is the number of threads, if I divide 32 by 2 I get 16 !
Does this mean I have 4 4 core cpus or do I have 2 8 core cpus?
Am I missing something?
