Create a second boot partition on the second drive and mount it as /boot2.
Now copy all files from /boot to /boot2.
After this create a second lilo configuration file (i.e. /etc/lilo.conf.backup)
boot=/dev/sdb
disk=/dev/sdb bios=0x80
map=/boot2/map
install=/boot2/boot.b
image=/boot2/vmlinuz
root=/dev/md0
label=linux
Now run 'lilo -C /etc/lilo.conf.backup'. This one will probably boot as /dev/sda from
the
former /dev/sdb when you remove /dev/sda (indeed I tested this an EIDE configuration
with
/dev/hda and /dev/hdc, not with SCSI). Please remark, that it will come up as
/dev/sda!!!
You will have to make sure that in case of loss of any of your disks your system will
come up with some reasonable disk names: Lets assume you have /dev/sda, sdb, sdc and
sdd
forming a RAID-1 /dev/md0 consisting of /dev/sdb and /dev/sdd. You will be out of the
game whenever you loose sda or sdb ...
