Greetings,
I gave up recovering from mksysb, it seems your SPOT must
match your patch level. So if i have
5.3 PL 3 SPOT but trough patches my actual system is now at PL 6 the
mksysb restore will require
the SPOT to be at 6.
So here is for the question. I also admin solaris and for
solaris, IBM has the procedure to recover
the system from adsm, given a totally hosed system, can I recover from
ADSM? This is IBM after all.
If you destroy your system, mksysb is the answer because it (with NIM)
is a bootable backup that understands LVM. The p-series firmware does
not know LVM or JFS, so you need something to handle that. Trouble is,
AIX stores LVM stuff in the ODM database, so you need to handle that
too. File restore using TSM is out... You need an intelligent mechanism.
You can create a SPOT from an mksysb image by defining the image as a
NIM object first and then creating a SPOT and using it as the source for
the SPOT.
You can only use this SPOT for that image, and it cannot be used to boot
in maintenance mode. You need a full spot for that. The NIM master
always needs to be at the highest level of AIX it services.
Sysback is a nice product, but is a separate feature requiring setup.

Good luck,

You may want to check http://www.storix.com
We use it for about 60 of our aix servers.
its like sysback but better (from what i know of sysback).
you dont have to worry about spots etc either and you can netboot via
a storix bootimage or create seperate storix boot media on cd/tape.
it is best to have an uptodate boot image created from each server as
then you are not going to have probs when booting (booting from a boot
image made from different hardware does not always work).
what u can do tho is follow this scenario
1. the server is down and u have no boot image
2. no prob, just reinstall aix (2 hrs), install storix (5mins), create
boot image
3. boot server from bot image and insall storix mksysb. use storix to
create non-rootvg vg's and lv's
4. restore the actual non-rootvg data from normal tsm backups.
you increase the recovery time by a couple of hours but you avoid
having to have uptodate boot oimages.
it depends on the criticality of your servers whether its better to
have2 hrs longer or maintain the boot images uptodate.
it doesnt tie in with tsm, we create or storix mksysb to disk on the
storix server and then just backup that with tsm
