After updating the kernel you need to run LILO to update the bootloader but LILO quits with errors.

# lilo -d
running on chrp
Boot target is /dev/sda1
add note section for RS6K
MKDOSFS options: -s 1 -F 16 -n 'rootlv'
+ bootpartkernelname=sda1
++ dmsetup ls
+ [[ system-part2 (253, 2)
vg00-rootlv (253, 3)
system-part1 (253, 1)
system (253, 0)
vg00-lvol0 (253, 7)
vg00-tmplv (253, 5)
vg00-varlv (253, 6)
vg00-swaplv (253, 4) == *sda1* ]]
+ set +x
mkfs.msdos 2.11 (12 Mar 2005)
mkfs.msdos: unable to open /dev/sda1

The result of this problem is that you will not be able to boot the system.


The problem is reported to engineering. Fix will be publish as soon as possible.

Workaround :
Please boot into the rescue mode
Mount the root device
Example :
# mount /dev/vg00/rootvg /mnt
# mount -o bind /dev /mnt/dev
# mount -o bind /proc /mnt/proc
# mount -o bind /sys /mnt/sys

Change root to /mnt

# chroot /mnt

Run lilo

# lilo

The bootloader will be updated and the system can be booted normal again.
