Dual CPU, but Redhat sees only one

server. The only problem is that Redhat 6.1's SMP kernel won't
see more than one of the cpus. I thought Redhat shipped their
product with smp-kernels so that it would recognize dual CPUs
"right out of the box"...?
What do I do?

Hmm. I have plans to change mb's soon to a dual processor. I was
of the impression that (for Redhat) all that was necessary was to
d/l and run the appropriate kernel.*.smp.rpm.

> recompile the kernel with SMP support
I've tried compiling a new kernel with SMP-support...
Besides, the kernel that ships with RedHat IS smp.
I've also tried upgrading to 2.2.14smp-kernel (rpm from RedHat)
No matter, I still have only one cpu showing up when I do 'cat /proc/cpuinfo',
or using "top".
Any more suggestions?

It didn't install that kernel by default - I had to do it via the EXPERT
install route - bit scary - I ain't no expert! But there's only four
kernels there, and one is labelled SMP.

Mine is labelled SMP as well... And it came by using the default
installation routine (which sucks, btw... Very GUI but not very good)
...but it still doesn't see more than one CPU

cpu0 and a cpu1? Linux starts with 0 not 1. Try 'cat /proc/cpuinfo |less' and
see if it shows both cpu's.

Even if you sound a bit consending it's ok, as long as you're trying
to help. :-)
Yes, I know that linux starts at 0, and no, it doesn't show more
than CPU 0. Here's my output from 'cat /proc/cpuinfo':
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 7
model name : Pentium III (Katmai)
stepping : 3
cpu MHz : 598.439155
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr xmm
bogomips : 596.38
Hmm... it's quite annoying with problems like this one. This is our
first "big" linux-server, and I had hoped it would prove to everyone
in our company that Linux is up there among the big ones like hp-ux
and Solaris.
If I can't make it use both CPU-s though, I think the image
cracks a bit...

New installation of RedHat 6.1 on a Compaq Proliant with dual Pentium III/600 Mhz processors...

The next thing to check is that you are actually using the kernel you
_think_ you are using.
Do a "uname -a". You should see something like:
Linux valhalla 2.2.14 #1 SMP Sun Feb 13 16:20:03 PST 2000 i686 unknown
^^^
If you do not see this, check your "/etc/lilo.conf". If there is a
"default" line, check the corresponding "image" line. If there is no
"default" line, check the first "image" line. The "image" line should
point to the kernel in question. Then run "lilo" to activate any
changes you have made.
If still no go, check that any other operating system you have on the
machine (Windows?) sees both CPUs.

Yes, I AM using my smp kernel. In fact I have only 1 kernel on the
machine right now, the following:
Linux lnk-osl-27-1395 2.2.14-1.1.0smp #1 SMP Thu Jan 6 05:07:14 EST 2000 i686 unknown

Other operating systems? You must be joking, right?

you suppose that this may be something to do with the fact that you are using a Compac? All my
machines are home built, you could ask Compac if they know of any issues, kind of a long shot but
maybe worth a try. The reason I say this is I have an OLD Compac Prolinea, I use as a router and I
had to do quite a bit of fiddling to get Linux to install properly ( could be due to vintage---but?).

The only possible reason now is that your second CPU is not working
(not plugged in properly?).
That's why it would be interesting to see what a possible second OS
came up with. No joke. What you can do, though, is to enter the BIOS
setup for your machine. Usually this will tell you how many CPUs you
have (for instance, a Phoenix BIOS will display two "CPU IDs").
Also, a wild thought: Perhaps your /proc filesystem is not mounted,
and what you see in there are actual disk files that somehow were
copied in there? Thus, the information would be static. "mount" will
tell you whether that's the case.

Yes, I found the answer!
There was one small thing I had forgotten (or overlooked)
and that was setting the "Primary Operating System" in the
Compaq Smart-Start utility to "SCO Unix". I found this on the
page you mentioned, Frode, so thank you very much.
So, that's the solution folks: Don't forget to set up your server with
smart-start first, choosing SCO Unix as your primary operating system,
when using Compaq.
Thanks to all of you who tried to help

Incredible!!!!!!!!!
Now I really know why I only sell Compaq and would never buy one!
Sorry about that cheap shot Roar Petersen. I have 5 smp machines lying
around here all built by me. Trust me I am no VA LINUX either. Grab
RedHat v6.1 and installed. Everything seen all systems go within 20
minutes.
Good Luck when your next trouble hits on your compaq.
