Hello Sun Managers,
Thanks for all the replies. It was obvious from the responses that I hadn't
stated the problem at all clearly. So here goes again:
A diskless SLC was to be upgraded to standalone.
I successfully formatted and partitioned the disk on the machine in question
and put a full 4.1.3 system on the disk from a local CDROM.
I rebuilt the kernel and rebooted the machine. It booted OK. I rebuilt the
kernel again and decided as the machine was down, I would take the opportunity
to remove the now redundant CDROM.
I tried to reboot the machine. It started to boot from the disk OK but at the
point where it says:
root on /dev/sd3a fstype 4.2
swap on /dev/sd3b fstype spec
dump on /dev/sd3b fstype spec
the screen went black and the machine started to test memory.
OK I thought, the kernel is corrupt or misconfigured. I then tried to reboot
the machine from the net using b le(). Again the machine booted correctly until
it reached the same point in the boot sequence as above when the same thing
occurred i.e:
dump on sol:/export/swap/helen fstype nfs
At this point I suspected that the SCSI bus was incorrectly terminated. I there-
fore swapped the terminator for a known good one. The little LED lit up, but
the machine still refused to pass the "dump on /dev/sd3b" line.
I therefore removed the disk. The machine booted correctly to the multiuser
prompt. I therefore suspected the disk as loading the SCSI bus strangely.
I wrote my first message to sun-managers, and went home.
The next day (today) I tried the disk on a different machine. It worked
perfectly I therefore concluded that the machine was broken and a new CPU
is being installed as soon as possible.
So it seems to be a HARWARE fault.
Thanks again to:
