It's weird though since I can image our IBM x330's fine with Oscar 3.0 and RH 9.0... so it may not really be SIS... unless you guys have the newer models (our highest-end x330 are p3-1.6GHz...)

Jason, Bernard, One other issue that may be coming in is that SIS builds it's own initrd.img file on the nodes and may not be including all the required SCSI modules during booting.
The problem is almost certainly a kernel issue, and as such you will need to watch closely during the boot for errors, etc. It probably will give some message about failing to find or load some SCSI module, but with out seeing the kernel messages, it is pretty hard to diagnose.

Hey Jason:

I haven't tried installing Man 9.2 on the cluster nodes, only on the head node (which is almost identical to the cluster nodes.) Still, it's probably worth doing, and I'll try that first thing tomorrow morning.
If they are the same hardware then that probably won't make much of a difference.
My colleague indicates that he's seen the "unable to mount root fs, kernel panic" message before when trying to install Mandrake on IBM x330/335s, and that he worked around it by building a different kernel. Perhaps it's a kernel problem and not a configuration one. Does OSCAR simply use the kernel which the head node uses? If so, and if the kernel distributed with Man 9.2 works on both the head and the cluster nodes, then at least it should be clear that it's not a kernel problem... I think. :)
I am not too sure about kernel stuff but I think SIS uses its own kernel when building images (not related to the kernel on the headnode). You might want to look into the OSCAR package kernel-switcher to see if that gives you any insight. I would also recommend going through the mailing-list archives - I have seen 'similar' questions asked in the past, so you might actually be able to get something out of it.
I'll have to do a little more work on this. Any more suggestions from anyone else would be appreciated. I'm not completely against RH9.0, but the fact that it's no longer supported by RedHat anymore, coupled with the fact that we're a Mandrake shop around here and have more expertise in Mandrake, makes me want to try and get it working with Mandrake. Of course, I could always try RH using one of the cluster nodes as a head node and go from there.
I think it'd be cool if after this exercise you emerge and actually got it working under Mandrake 9.2 and we can all learn from this (and improve our current support).
But if it is any incentive, we are also using the IBM x330's and we have no issues with RH 9.0 :-)
Good luck!
Cheers,
Bernard
