Wish I knew.... It all happened after I was testing to see what would
happen under various failure conditions. I had three identical drives that
I was experimenting with by removing and replacing from the RAID1 array.
At one stage I - (could kick myself now...) had all three drives connected
simultaneously and I suspect that this is when the problem ocurred.
It seems that one of the drives was marked as a spare drive and ever since
then LILO does not see /dev/hda.
