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

Semantics, with Max and Khai

K: Yay! Thank you dad!
M: What did he do?
K: he changed my lights to the bluish color
M: Hugh. Mine are still yellow.
K: it’s because I complained. If you whine, you don’t get anything, but if you complain, you do.

Greenhouse restaurant

Very tasty food, relaxed atmosphere, and our waitress, Andrea, is taking care of us well. It’s our “day before 12th anniversary” outing.

More Google frustrations

Searching the iOS 5 map now pulls up sponsored links which often overlay what I am actually looking for.

I understand doing this on the free download app, but the old OS version should not do this.

I guess I should update… The TomTom iOS6 version has been pretty good for me other than missing some 6-month construction in 2 places, and searching sub-city regions works better for me.

On the flip side, TomTom regular data quality went downhill after version 9.

Other issues with Google have been their recent SSL policy changes, summary judgement to cancel my adwords account, automatic downloading of my ipad pics after plus app update, calendar monopoly without authenticated interop, and overall data monopoly while being advert driven rather than privacy/service driven.

Disaster Recovery #hurricaneSandy

I’m not really able bodied to haul debris, but I do computer system and storage builds, new and post disaster. Mostly AIX and Linux, but some other skills too. How can I hook up with people and companies in the northeast to help them recover? Just need a dry spot with boxes, power, cooling, access, and a way there.
