Topic: SME Server with 2 CPUs…???

[mgic_box]

Hello everybody.

Good day.

I have recently installed a second CPU on a running SME server.
The second (so I have now 2) CPU is correctly detected on the bios, and I have even installed a version of windows on this machine, and the window detects the 2 cup’s.

On the SME server, when I run htop (nice toll!!!) I only (still) see (only) one (1) CPU. So, I ask, if there is need to run any hardware detection routine, or whatever… to detect and use the second CPU on SME Server?

Thanks in advance.

You should reboot your server AND while in GRUB screen choose a kernel with SMP in his name (latest version is better) from list.

This way SME will show you two CPUs on htop.

What CPU's are they ?

Try typing:

cat /proc/cpuinfo

this will tell you more infor

mgic_box,

Had you completed the above before running Byte's code?

You are still only seeing one and the non SMP version of the kernel will not see (or use) more then that.

Code: [Select]

uname -a
should return something like this:

Linux pifc-mercy 2.6.9-67.0.7.ELsmp #1 SMP Sat Mar 15 06:54:55 EDT 2008 i686 i686 i386 GNU/Linux

  One more reboot, got the falw. options:

  - SME Server (2.69.55.0.6.ELsmp)
  - SME Server (2.69.55.0.6.EL)
  - SME Server (2.69.55.0.2.ELsmp)
  - SME Server-up (2.69.55.0.2.EL)

 Which one should I chose?

 Thanks.

  - SME Server (2.69.55.0.6.ELsmp)

Is the most recent on your list, BUT all of those are older kernels now, so you should upgrade your server and when done select (if not already selected for you)

SME Server (2.6.9-67.0.7.ELsmp)

oops, I think it is time for a bug report. You have the correct kernel running now but you still are not using the second processor.

[janet]

mgic_box

When there are major hardware changes in a box, such as adding a second CPU, you should do a install/upgrade from the CD, so the OS correctly detects the hardware and installs correct drivers etc.

You should really upgrade your server, as you are running an old version of sme.

So download a sme 7.3 CD, do a upgrade install from the CD, and then run yum update, to get the latest updates.

mary,

You are right (as usual).

[CharlieBrady]

When there are major hardware changes in a box, such as adding a second CPU, you should do a install/upgrade from the CD, so the OS correctly detects the hardware and installs correct drivers etc.

No, that is not correct for SME server. All drivers are bundled with the kernel rpm, so all systems already have the full complement of provided drivers.

[CharlieBrady]

You have the correct kernel running now but you still are not using the second processor.

That is a hardware and/or BIOS issue. There's nothing SME server software can do to fix that.

What about this?
