Recovery From A Deleted /dev Directory in AIX

This is from AIXMIND, on March 26, 2010 2:46 pm
It doesn't show up high enough in search queries, so I'm duplicating it here.
Note that AIX recreates most of /dev on boot, but we need a certain amount.

===============================================
Problem(Abstract): The /dev directory was accidentally deleted.
===============================================
Symptom: System wont boot
===============================================
Environment: AIX 5.3 (and others)
==============================================
Resolving the problem

Boot system into maintenance mode.
Access a root volume group before mounting filesystems

mount /dev/hd4 /mnt
mount /dev/hd2 /mnt/usr
mknod /mnt/dev/hd1 b 10 8
mknod /mnt/dev/hd2 b 10 5
mknod /mnt/dev/hd3 b 10 7
mknod /mnt/dev/hd4 b 10 4
mknod /mnt/dev/hd5 b 10 1
mknod /mnt/dev/hd6 b 10 2
mknod /mnt/dev/hd8 b 10 3
mknod /mnt/dev/hd9var b 10 6
umount /mnt/usr
umount /mnt
shutdown -Fr
