Hi Tyler:
Do you have both IDE and
SCSI HDs in your compute nodes?
Can you boot one of your
compute nodes (which failed installation) into rescue mode (using the first CD
of RHEL4 and typing "linux rescue" at the prompt) and show us the contents of
/boot/grub/menu.lst (of the HD).
It looks like Grub was
not installed properly...
P.S. Kernel and
initrd.img of your installed node should reside in /boot - SystemConfigurator
creates a ramdisk for you on the fly though, and the filename is prefixed by
"sc-".
Cheers,
Bernard
Hi.
I have successfully created an image and am now trying to network boot a
single node. The network install finishes (apparently with success) but
it does give some "problem" messages before the boot process is done (see
below). After the network boot, I reboot again (from the hard drive),
but I get a grub> prompt. From the prompt, I have tried to load the
kernel but I dont know where it lives. I have also tried to "find" the
image, based on the name I originally gave it, but it cant seem to find
it. So, it seems something is not right. Where should I look to
investigate the problem further?
Thanks.

Finally, is there a file created that contains all of the network
boot screen output? I found one file in /tmp called si.log, but it
contains only a small bit of the
process.
