I've read through your question 3 times now and I'm still trying to figure out 
what you're doing :)

You're mentioning creating backupsets. For me, a backupset is a way of 
restoring a client without having to transfer the data across the LAN. But 
you're also mentioning TSM servers placed on AIX and Linux respectively. Are 
you trying to move a TSM server from AIX to Linux? I've never heard of anyone 
transfering client data betweeen TSM servers using backupsets, I didnt even 
know it was possible. Did you mix it up and mean export tapes? 

Cant answer for AIX > Linux, but for example AIX > Windows wont work since the 
way the OS writes/reads labels of the tape isnt the same (tried it, didnt work 
for me, perhaps someone else was more lucky).

Is there a reason you dont want to do a server-to-server export?

Generally (and I'm only talking from my own experience) tapes, databases and 
normal volumes arent compatible between OS's. The way they handle tapes are 
just too different.

If you try to explain what you're trying to accomplish, perhaps it's easier to 
help. Or it's just getting late and I'm too tired :)

Best Regards

Ärende: [ADSM-L] Backupset restore question - different server OS's

I am currently running TSM V5.5 on AIX.  I am setting up a TSM V6.2 server on 
Linux at a new data center.  I would like to use backup sets to transfer client 
data from the old to the new data centers. This backupset data will be used to 
populate the newly built clients - not as a backup data store.  Both the old 
and new data centers have IBM TS1120 drives in their TS3500 libraries.  I don't 
plan to attach each client to tape drives and would perform the backupset 
restore via TSM server.

Does anyone know or have experienced creating a backup set on a TSM V5 server 
on AIX and then recovering that backup to a TSM V6 server on Linux? The Linux 
server would need to generate a TOC from the tape created by the AIX server.

The TSM V6.2 server should be able to work with the backup set.  It is the OS 
tape read/write compatibility that I am unsure of.  I don't currently have a 
Linux box to play with and cannot test this scenario.

Your comment is highly welcomed.
