On AIX upgrade you will have to uninstall TSM Driver for 4.3 and later
install the one for 5L. It is recommended to write down the driver
configuration by saving the output of 'lsdev -Cc adsmtape' and 'lsdev -Cc
library' - on uninstall of the driver all those devices are deleted and
have to be recreated. If there are Magstar or IBM Ultrium drives
Atape.driver might need to be upgraded (better before OS upgrade).
I cannot say what caused ATM adapter problem but it is outside TSM.
Library and tape definitions should not be lost. Only /dev/lbX and
/dev/mtY will be deleted as mentioned above. Even if they are messed and
have to be recreated it can be done without modifying/deleting the
devclass defined on top of them. And there is no need to mess with
stgpools as well. You can delete all the drives from a library and
recreate them without problem. You can delete library and drives without
touching the devclass. If library is created again under same name nothing
else has to be done. If the library name is changed you can 'upd dev
<class> libr=<new library name>'. Again no need to delete the devclass and
stgpools. And volumes will stay in place, just libvolumes will show up in
"another" library. After checkin in the "new" library TSM will realize
where they are and continue using them.

Subject:        AW: AIX Upgrade with TSM

We upgraded our NSM (3466-C00) just a week ago from AIX 4.3.3 and TSM
4.1.2.5 to
AIX 5.1 and TSM 4.2.1.9.
Wehad two problems with the upgrade:
1) The definition of our second network adapter (ATM 155) was lost
2) The library and tape definitions were lost. So the "next storage pool"
definitions
in our disk storage pool were lost as well and had to be reconfigured.

So, backup all TSM and AIX definitions and your upgrade will run fine.

Kind regards
