Number of Processors

Sergio Crespo — Mon, 03 Jan 2005 05:51:12 GMT

Hi

Hope you can help me with this one. We have a rx7620 ia64 with 8 Itanium 2 processors 1500Mhz. Laste week we've installed HPUX 11.23 and now we only have 5 processors visible.

# ioscan -fnkC processor
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
processor 0 0/120 processor CLAIMED PROCESSOR Processor
processor 1 1/120 processor CLAIMED PROCESSOR Processor
processor 2 1/121 processor CLAIMED PROCESSOR Processor
processor 3 1/122 processor CLAIMED PROCESSOR Processor
processor 4 1/123 processor CLAIMED PROCESSOR Processor

Any clues?

What does ioscan -funC processor give you?
and what does ioscan -C processor give you?

Hi,
try insf -e ( install the missed device file)
and then
ioscan -fnCprocessor (without -k)

Hi Sergio,

It is possible that 3 of the processors in a cell board got deconfigured.

Check this through the MP log and mstm. You can enable the processors from the EFI menu using cpuconfig command.

With regards,
Mohan.

Hi :)
Thankx for the Tips but I'm still with the issue here...
I've tryed the (#insf -e; ioscan -fnC processor) and it didn't work out...

The output:
# ioscan -C processor
H/W Path Class Description
===================================
0/120 processor Processor
1/120 processor Processor
1/121 processor Processor
1/122 processor Processor
1/123 processor Processor

The strange thing is that from the H/W path "0" only one processor is shown, and in the H/W path "1" all processors are shown.

Hi sergio,

Look at my previous post. It is clear that 3 CPUs are deconfigured in 1 cell board.

Did you check the logs and procedure I indicated?

Mohan.

Hi Sergio,

As already mentioned, try cstm:

cstm
cstm> map
cstm> sel d

Device number of the CPUs you see in the map list. Then continue with:

cstm> info
cstm> wait
cstm> il

Look for every processor for:

Active: Yes

=============
Glance might give you a clue as well (if installed).

If you still can't see it, there is most probably something wrong with your hardware recognising the CPUs, perhaps a board issue, better log a (H/W) Call with HP if you still don't see them.

Best regards,

Peter.

Thank you all very much...

The problem is solved

I've been able to go trough EFI console and enabled the 3 missing processors. I can't still understang why have they been unconfigured...

Thankx

Hi Sergio,

Please upgrade the firmware to version 3.0, which is supposed to fix such deconfig problems.

I hv installed this firmware in around 10 systems.
