Hi,

I have a TSM 5.2 running on AIX, IBM TS3500 library With 6 LTO-1 drives connected to it. the library capacity is 253 tapes.

Now we want to move to Latest TSM Version With Latest Library with LTO5 Drives

Once the new setup is up and running, i want to migrate the DB to latest version, and also move all my data from LTO1 Cartridges to LTO5 Cat rides.

so that i can crash all my LTO1 Tapes (Around 1500),


1) Can some pls suggest how i can do this ?

2) How to know the size of total data in tapes since day 1 ?

3)is these steps are correct ?
first i will define a disk pool,
then move data from the LTO1 to diskpool
then install new version, migrate DB,
the move data from diskpool to new LTO5 pool

4)Before Migrating i want to delete some data from the tapes ex: all data of node1 before 2009 is this possible ?

5) Usually when stgpool out of space we cheeck out 100% full tapes from lib and check in free tape and assign to stgpool, since last 5years almost 1500 full tapes are in boxes, when some restoration comes, TSM will ask for check in the required volumes, and we check in, once finishes we removes, during the migration check-in check-out task will become difficult, How can i shorten this procedure

6)usually LTO5 media box shows that 3TB (2:1) compression, whether TSM uses this compression ratio ?



Thankyou

It sounds like you have a fairly lengthy list of items to address there,
not least being on such an old version of TSM but also how you are
managing your storage. In my opinion, you need someone to come and
visit you and assess your environment then come up with a plan of action
that will get you to where you need to be. A local business partner
that knows what they are doing will be able to do that and give you a
good idea (and price) for the hardware you actually need rather than
some sales pitch.

You might be able to upgrade the existing 3584, adding new drives and
partitioning, depending on the support status. I suspect you will need
at least a new server for TSM, and might want to select what you're
doing about platform choice etc while thinking about how to migrate
across.

I agree with Xav, this is something you want to do with a partner that has
done this kind of stuff before.
There are all sorts of things that need to be sorted, if you really need to
migrate the TSM db you need to upgrade to 5.4 or 5.5, then you have the
issue of LTO-5 not being able to read LTO-1 tapes so you need to (for
example) connect both libraries, make new storagepools etc etc.

But there also might be another route, the let most of the data die on the
old system, migratie via server-to-server what needs to be saved and start
over, that way you don't have that much work on the old evironment (you do
need to upgrade TSM) and it's not such a big-bang migration.
However you do this, it's going to take a some solid preparation and
planning.

Make sure you get somebody that has good TSM 5, TSM 6 and LTO tape skills.

This has been the migration strategy we adopted, and are right now in
the middle of. New server machine, new TSM version, the client nodes
make fresh, new backups spread over a period of time. The old system
gradually expires away until you can get rid of it.

Run the new server on 6.2.3, instead of 6.3.0, for better supported
working with existing V5 servers. V6.3 with V5.5 is not supported.
However V6.2.3 does support working with V5.5, and it will be supported
for a while. You could do this migration first to V6.2.3, and then
upgrade to the very latest version later easily.
