Hi,
I am on SPARC T5-2 with SOLARIS 11.1 / LDOM
From ILOM web interface i see 2 CPU Sparc
From the primary LDOM OS i see 1 CPU
root@LUOVM01 ~ # /usr/bin/kstat -m cpu_info | grep chip_id | uniq
chip_id 0
what is wrong ?
What is the output of psrinfo ?
Use ldm commands to check it, you will have 256 threads available as VCPU which is equivalent of 2 CPU, 16 core each. Each core has 8 threads.
You can only see the vcpu alocated to primary domain from that domain.
ldm list -o cpu
Hope that helps
Regards
Peasant.

From what I can see from psrinfo , there is only one cpu in your system...
It will show only 16 threads which are allocated to primary domain.
If you put ldm set-vcpu 8 primary, then psrinfo will show only 8...

The output of psrinfo shows the cores NOT the vcpu's of the system. So the output of ldom commands can not be compared to the psrinfo output. This system has only access to 16 cores and that means access to ONE physical cpu. With the 16 vcpu's assigned to the primary domain, the psrinfo should only show 2 cores acording to your deffinition.
For your understanding -> 1 Sparc T5 cpu 16 cores and 8 threads per core = 128 vcpu's!
So we arrive at the main question that i wonder :
on this T5-2 box : i see 255 vcpu from primary so i can say theyr is Sparc T5 cpu 16 cores and 8 threads per core.
But why kstat say only one chip_id
MadeInGermany how do you then explain this output :
root@myhost:~# uname -a
SunOS myhost 5.11 11.1 sun4v sparc sun4v
root@myhost:~# psrinfo

If you see 256 vcpu's then there are 2 physical cpu's present. I don't know about the kstat output... And I don't have a sparc system to test at my hand right now.
It actually shows the threads (a.k.a. vcpu's).
Was able to test it today on a sparc system... You are right!
yes you are.
thx for help
