machinfo - wron CPU information

Hello Experts!

I have configured 3 virtual partitions on Integrity SuperdDome:
vPar1: 8 x dual core 1.6/24M
vPar2: 8 x dual core 1.6/24M
vPar3: 3 x dual core 1.6/24M

Only in case of vPar3 'machinfo' reports correct information about processors.

vPar1&vPar2:

## /usr/contrib/bin/machinfo ##

All patches installed on these three vPars are the same. PHCO_36489 has been installed.

Any advice?

Re: machinfo - wron CPU information

Could you post:

#vparstatus

#parstatus -w

and with the number of partition you get in the ouput

#parstatus -V -p partitionNumber


Thnx
Windows?, no thanks

Re: machinfo - wron CPU information

I'm not sure where the problem is ...

Is it this?

9 Intel(R) Itanium 2 9100 series processors (1.6 GHz, 12 MB)
533 MT/s bus, CPU version A1
16 logical processors

9 vs. 16 cores?


How about

# icapstatus

# parstatus

# vparstatus -A

Hope this helps!
Regards
Torsten.

Re: machinfo - wron CPU information

9 vs. 16 cores is the first confusion.
The second thing is processor cache memory.
Machinfo reports 1.6 GHz, 12 MB instead of 1.6 GHz, 24 MB.

Please look at the attached outputs.

All processors are assigned and active.

Re: machinfo - wron CPU information

You have to think that in 11.31 with hyperthreadind enabled, you have in each cell four sockets, 8 cores, 16 lcpus.

So it looks like in 11.31 you are adding lcpus to you vpars, not cores.

And machinfo shows cores.

But to make sense of the 9 cores output, we need a:

#parstatus

and

#icapstatus


Windows?, no thanks

You can't. Only a moderator can do this.

Re: machinfo - wron CPU information

I don't have access to the server at this moment.
HT is diabled.
vPar1 - 8 dual-core processors
vPar2 - 8 dual-core processors
vPar3 - 3 dual-core processors

I really would like to delete the attached file as it's not the file which I meant. Could you please help me?

It is better to reply to an existing thread rather than create 10s of extra threads.

I probably should have the moderator delete these old ones. :-)

Sorry Dennis, of course one should add a post to this (your ;-)) thread.

Re: machinfo - wron CPU information

Regarding the patches:

I would do something like a "patch_verify" on both vPars and run a "diff" to compare. Maybe one is missing? Same for "swlist".

Hope this helps!

Torsten.

I've done this before (show_patches -a; swlist)
The same software, the same patches

Re: machinfo - wron CPU information

Hi,

you can pull the processor information from the respective vPar through System Management Homepage

http://:2301

else

you can get the Information from MP
MP>CM>DF
select the CPU FRU.

Otherwise

try /opt/sfm/bin/CIMUtil -e root/cimv2 HP_Processor and look for the field "Description"

Thanks

Re: machinfo - wron CPU information

This is a bit strange ...

The other tools are reporting correctly, as far as I can see.

Could you please post a "machinfo -v" from vPar1 and vPar3?

And:

# echo "sel dev 1;info;wait;il" | cstm

(this should list all FRUs).

Hope this helps!
Regards
Torsten.

are you completely sure?

run sysdiff between the vPars - this will show up *any* software differences

sysdiff sys1 sys2

Re: machinfo - wron CPU information

OK, let me take a *guess* at whats causing this...

remember that in vPars we can split CPU cores between partitions... so its possible to have the 1 core with 1/2 the cache in one vPar, and the other core with the other 1/2 of cache in the other vPar.

Now look at the list of CPUs in different vPars:

vPar1:
Boot processor [Path]: 0.121
Monitor assigned [Path]: 0.122
0.123
0.124
1.120
1.121
1.122
1.123
2.120
2.121
2.122
2.123
3.120
3.121
3.122
3.123

vPar2:
Boot processor [Path]: 0.120
Monitor assigned [Path]: 0.125
0.126
0.127
1.124
1.125
1.132
1.133
2.124
2.125
2.132
2.133
3.124
3.125
3.132
3.133

vPar3:
Boot processor [Path]: 5.120
Monitor assigned [Path]: 5.121
5.124
5.125
7.120
7.121

Note that *only* vPar 3 has the other core of the boot processor in the same vPar. (5.120 and 5.121) - So when the macinfo runs, it only gets a report on 1/2 of the resources of the boot processor (it wouldn't surprise me if machinfo made the reasonable assumption that all other processors in the vPar are like the boot processor) It would be interesting to see what you got if you moved these processors around...

Like I said - this is a guess...

Sorry for delay. I don't have a constant access to this machine.

Re: machinfo - wron CPU information

I don't know how machinfo exactly works, but since the cores of the boot processor are splitted and assigned to different vPars, I think this tool only detects the cache that belongs to one of the cores (12MB). The same reason would affect the CPU count. So I agree to Duncan's theory.
In fact all of your CPUs are the same.

Some notes about "Splitting sibling CPUs":

Hope this helps!
