Yes, things tend to move quickly around here and I might be attempting to use
TSM in an unconventional manner.
I have to move about 90 TB of data from data center A to Data center B. The
data centers have dissimilar SAN storage and very limited WAN connectivity
between each other. Each server at the new data center will be a new system
and needs to be seeded with data from the currently running system. Some
servers will only require a few GB of seed data while others will require
several hundred GB and a few have several TB of seed data. I have to have a
data migration solution ready next week and should begin migration shortly
after Labor Day.
My Plan in a nutshell:
1. Generate a backupset on a TSM V5.5 AIX server on encrypted 3592 media
at data center A
2. Ship the encrypted media to data center B
3. Define a backupset and generate a backupsetTOC(optional) from the
encrypted 3592 media on the TSM v6.2 Linux server at Data center B. Data center
B has the appropriate encryption keys to decrypt the media.
4. Restore backupset data to the appropriate client from the TSM V6.2
Linux server at Data center B
- No TSM DB Upgrades required or planed. The TSM V6.2 Linux server is a
fresh install.
There are two methods of performing a backupset restore - 1. Attach client to
media containing the backupset data OR 2. From a TSM server containing
backupset data. (Ref: TSM for AIX V5.5 Admin Guide - pg 454). I plan to
perform the second.
I plan to move the backupset data from server to serverB as described in TSM
for AIX V6.2 Admin Guide pg. 520 as such there should be no issues with DB
differences between TSM V5 & V6 unless the data written to the backupset media
is significantly different. I also ran across "IC62418: Backup set and Table
of Contents support in Tivoli Storage Manager Version 6.1" which discusses
backupset compatibility between V5 TSM servers and V6.1.2 or higher TSM servers
in the "Problem Conclusion" section.
Since I have not built the Linux TSM server yet, I cannot test the
compatibility of the 3592 media written by AIX and then read (hopefully) by
Linux and this has me concerned. It looks like a backupsetTOC is not required
but would be nice to have.
Your comments are welcome.

Subject: [ADSM-L] Ang: [ADSM-L] Backupset restore question - different server
OS's
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 :)

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.
