Hey Drew,
Well yesterday when I tested it, I didn't create the separate ODM
test environment/directory. I just modified the live AIX ODM, and it still
pulled the original one out on reboot. I think the original is stored in:
"hd5" as a backup since that's the AIX boot block. I'll look more into that
but as for now just creating a separate environment/directory is the safest
bet with protecting production, and pointing to that directory in the
/.profile would be a good bet for now. Thanks!.

Thanks Justin,
I appreciate it. What if you copy the testobm into the objrepos
directories
once you testodm is good?
Would that work.
Thanks again for your input.
Drew

Subject: modify the odm
FYI...With the procedure below the hdisks do not stay modified after system
reboot it goes right back to: "hdisk1". I will do some more reboot testing
this afternoon and let you know. It may be a boot block thing that it
restores the original O/S ODM. I'll let you know. Another option for now is
to put the modified ODM in that separate "/test" directory then put the
"ODMDIR=/test/" in your /.profile or an rc script now that works. I'll let
you know if I find a fix for it.
Backup the following directory first:
/etc/objrepos/* -- Another way to ensure you don't screw up production is
to copy all contents of the "/etc/objrepos/*" to a temporary directory like
"/test/" then set the following system variable:
# export ODMDIR=/test/ <ENTER>
Then if it screws something up then just point it back to the original AIX
one:
# export ODMDIR=/etc/objrepos <ENTER>
DISCLAIMER: I will not be held responsible for anything that goes wrong LOL
HERE IT IS FOLLOW THIS STEP BY STEP...PLEASE BE CAREFUL

Hi everyone.
OK That's it. I want to modify the ODM! I have an extra 43p for personal
use
only and I want to go in and change the order of my disks. Can someone give
me the quick rundown. Just a couple of basic commands to get me going
I have only Hdisk0 and Hdisk1. I want to change the name of Hdisk1 to
Shoebiedo, but leave Hdisk0 alone.
Thanks,
Drew

Leaving the order as is presents you with information you may not have had
... the system was forced to add a new disk drive after the other two,
listing it out of order. This gives some "history" to the configuration
and, as such, might provide some troubleshooting information to the strong
problem-spy!
If you have programs or scripts that do this listing, simply add "| sort
-n"
to the output command.
And if this is the major item you have to worry about, I want YOUR job!!!!
;-)
Seriously, as stated below, the ODM mods are not involved nor difficult ...
but if one thing gets out of place, you're hosed. Definitely backup rootvg
and all other vgs and get your cds handy if you're going to make the mods.

You can always modify the ODM, but this is only if your really concerned
about the order to make it look pretty. Changing the disks id's in the odm
is non harmful if it's done right. You can name them "harddisk#" if you
want. Just go to the device table in the AIX odm and swap the entries for:
"hdisk11" and "hdisk11". Or just "rmdev" as the gentlemen below suggested
before the next time you reboot. If you decide to modify the ODM please
back it up so you can return to this state if you type or something. Backup
everything in: "/etc/objrepos" that is where the database is.

Thank you, but they all now contain live data, even
hdisk11 itself...hmmm
