Topic: SMP on e-smith sme server ???

[Murray Schwalbaum]

I just installed e-smith on my dual processor DEC prioris server. I use dual 133s (it's a bit silly but i want to use it). I installed SME server with no problem. It just is a it slow.

My question is, has anyone compiled a SMP kernel to run on a SME server? I want to make a howto on enabling SMP on a SME server but don't want to do it without getting LOTS of feedback and success/failure stories from the community.

Post your stories or suggestions here. If anyone wants to get a SMP box working, post here too. I want to hear from everyone.

This is my hacking project for the weekend (as well as a diskless sparcstation 10) I want to get this done and documented by early nex week.

Ummm...  SME ships by default supporting SMP.  Is it not working on your machine?

[Murray Schwalbaum]

Nope. It's not. I heard of other poeple having similar problems with different hardware. I know that recompiling the 2.2.19-xxx kernel will enable it but it just didn't detect it.

This is a dual processor i586 under redhat 7.3.

You might need to update your bios in order for e-smith to recognise your dual processor system. I'm running dual p3 833's and didn't have to do anything special - E-smith recognised the dual config and automatically installed both uniprocessor and smp kernels for me. Now when I boot I have a choice between either kernel. Gee I love my E-smith )

[Murray Schwalbaum]

It's the latest and greatest bios for the box. I'm going to double check now but I updated it recently. I am then going to bring it down and install RH 7.3 to verify that another OS recognizes the two processors.

Thanks for the comments.  I might be gone for the time it takes to install RH 7.3 and e-smith. -mps

Before you start installing other OSs, try installing (not upgrading!) the kernel-smp RPM from the 5.1.2 CD and adding a LILO entry for it.  That might do the trick.

[Murray Schwalbaum]

Did that even before I saw the post. The box is working now (well, sort of). I don't have any access to my cdrom because of driver issues. Nor my floppy disk.  I played around with mkinitrd to make some smp initrd images but it still doesn't give me access to the cdrom.

It is working but any comments as far as modules with smp would be helpfull. Does the lilo configuration on a smp box use a different initrd.img?
