Topic: Multi processor not seen

[jjcuk]

Just installed phpsysinfo and have just realised only 1 processor showing

[root@deepblack ~]# uname -a shows
Linux deepblack 2.6.9-34.ELsmp #1 SMP Wed Mar 8 00:27:03 CST 2006 i686 i686 i386 GNU/Linux

which I believe is the correct kernal for multi processor

running sme server 7 Final with latest updates

I have SME server 7 running on 2 servers of the same spec and both show the same results .
Compaq ProLiant 6400R's
specs here
 http://h18000.www1.hp.com/products/servers/proliant6400R/

both processors showed up in SME server 6 ?

any ideas ?

Time to update? (YUM)

Code: [Select]

[root@teri httpd.conf]#  uname -a
Linux teri 2.6.9-42.0.2.ELsmp #1 SMP Wed Aug 23 00:17:26 CDT 2006 i686 i686 i386 GNU/Linux
Processor 0 and 1 show here.

When YUM works it works well.
I haven't worked out why YUM doesn't always work;~/
But I'm certainly glad it does things properly when it does work.
I'll need to step aside to allow others more au fait with YUM...
Search for YUM in the forum threads, you'll find there are others
equally mystified and relieved;~)

[jjcuk]

well thanks for response anyway, it could easily be something silly I am doing I shall go back and re-read through forums

thanks

[piran]

Failing that do what I then do, hit the mirrors and manually download
the new stuff into a spare directory and then yum localinstall * it all.
Seems a bit quicker that way. FWIW running the htop utility will also
show you (both) processors and what they are doing.

[jjcuk]

ran a yum clean all then yum update and that has given me some updates

[root@shadow ~]# uname -a then gave me
Linux shadow 2.6.9-42.0.2.ELsmp #1 SMP Wed Aug 23 00:17:26 CDT 2006 i686 i686 i386 GNU/Linux

however after a reboot i am back to

[root@shadow ~]# uname -a
Linux shadow 2.6.9-34.ELsmp #1 SMP Wed Mar 8 00:27:03 CST 2006 i686 i686 i386 GNU/Linux

[piran]

Ah! VERY glibly... there's an update bug (possibly/allegedly).
During the reboot stop the flow at the white screen penguin
by hitting a key, manually select your kernel, continue.
The wrong kernel selection issue didn't happen again
for me after that.

[jjcuk]

yes I was reading about that bug earlier
and have been manually selecting the  sme ELsmp kernel which I believe is correct
for dual processor no?

[piran]

(English language syntax ambiguous)
For my dual Xeon processors I select the smp kernel.

[jjcuk]

mm

well the 4 choices are

centos (2.6.9-42.0.2 ELsmp)
centos (2.6.9-42.0.2 EL)
SME server (2.6.9-34.ELsmp)
SME server (2.6.9-34.EL)

so I assume you are using centos (2.6.9-42.0.2 ELsmp) and I have been using SME server (2.6.9-34.ELsmp), however I just switched to centos (2.6.9-42.0.2 ELsmp) and the results are the same

?

[piran]

I'm done now, the above worked for me earlier.
Recommend you join that bugzilla thread,
you'll tap into the project leaders;~)

[jjcuk]

yep ill have a look there thanks again

[jjcuk]

ah well

got a cant fix wont fix probably a kernal issue so looks like I will move back to sme 6

quote
If you are running the smp kernel and it isn't detecting both processors then
it is either going to be a hardware issue or a kernel issue.  Neither one of
which we can fix.  I'm closing this wontfix.

should be labeled cantfix not wont

Time to go shopping;~)
