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

Venkatesh B
