This actually brings up question. for me.

Our LTO2 drives are configured as ULTRIUM2C. Can we change the format to
DRIVE without data loss?

I believe you need to be at TSM server 5.2.4.0 to support LTO-3. Check the

I am about to replace a few of my LTO1 drives with LTO3.
Have started looking at all this stuff.  You didn't mention the platform for 
TSM server.  Mine is AIX and one other thing to do is
make sure the Atape driver is updated for LTO3 and
LTO3 WORM if you are using that, I will be.

Whatever platform, there is probably some OS stuff to check on.

Since LTO3 can read LTO1 media, why not just:

- In TSM, delete all your drives and paths
- Remove them from your OS
- Remove LTO-1 drives and replace with LTO-2 drives
- Allow your OS to recognize the new drives
- define the drives and paths to TSM
- Mark all your LTO-1 tapes as READONLY and just feed the library with LTO-3 
media from now on.

Since the devclass devtype is LTO no matter the flavor of LTO, you just need to 
make sure you specify the correct FORMAT= to be able
to read the ULTRIUM tapes and read/write the ULTRIUM3C tapes. FORMAT=DRIVE 
should handle that.

Now just let the LTO-1 tapes go away via expiration, reclamation or you can 
MOVE DATA them. Same storage pools and everything.

Same concept as was discussed on this list with upgrading 3590 drives to higher 
capacity drives. Like B's to E's.

Or am I on the wrong track here....? But I don't see why it wouldn't work.

Hello everyone again.
Current configuration:
TSM version 5.2.1.1
Library 3854
Drives Fibre attached LTO gen 1 (8)

The higher powers here have asked me to make up a plan to migrate from LTO Gen 
1 tapes to LTO Gen 3 tapes. I am putting a plan
together and was wondering if anyone has done this same move and if I am 
missing something in my plan.

1) Upgrade to TSM Server version 5.3
2) Hardware removal of 3 LTO Gen 1 drives, replaced with LTO Gen 3
3) New Dev Class for LTO Gen 3
4) New Stg pools for LTO Gen 3
5) Migrate data
6) Remove LTO Gen 1 drives remaining
7) Remove Old Storage pools.

I know this is a rather simplistic list here.
I also have a few questions will I have to change TSM to recognise the full 8 
character labels at this point as well?
Again if anyone has done this please reply, or if you see any fundemental flaw 
in my plan.
Thanks,
Andrew
