Hi,
If I where you I should like this instead.


1) Rename your old Diskpool
2) Create your File Pool with the same name as the old Diskpool
3) Update your Diskpool with HIGH=0 LOW=0 and NEXT=FILEPOOL (Disable Cache also 
if you have any)
4) Wait 2-3 days
5) Delete all Volumes in your DISKPOOL and Delete DISKPOOL

Now will you migrate the data and you can still backup to your new STG POOL 
with any issue an no extra work for you.

But why do you wanna move to FILE CLASS? Do you wanna use De-duplication? You 
know you will delay your backups and get a lot of fragmentation if you don't 
pre-create all Volumes? This has nothing with TSM really, but most of the issue 
is the filesystem, TSM need to create the file first before TSM can save any 
data to that volume, and that will create a delay.
If TSM creates multiple volumes, then will you get fragmentation.
I normally don't recommend anyone to have FILE CLASS as first storage pool. I 
only use that if a customer want to have a VTL but don't have any money to buy 
a real VTL.

Ämne: Move data from DISK pool to FILE pool

Dear TSMers,
We have TSM 5.5.1.1 under AIX 5.3.
I need to move data from DISK primary storage pool (raw logical volumes) to 
FILE primary storage pool (JFS2 file system).
There are 3 tape copy pools for DISK primary pool.
I am going to use next procedure:
1) create FILE primary storage pool with appropriate size;
2) move data from DISK primary storage pool to FILE pool by "move data <vol> 
stg=<FILE> reconstruct=no" (volume by volume);
3) delete DISK primary storage pool;
4) rename FILE storage pool to old DISK pool name.
My expectations:
1)     all existing tape copy pools, made for DISK pool, will be still legal 
for FILE primary storage pool (no need to make extra backups and it is possible 
to restore any data in FILE storage pool);
2)     no need to modify any copy groups connected to old DISK pool because of 
the same storage pool name;
3)     expiry process will continue to work normally;
4)     full/incremental backup history will be untouched by data movement.
Am I right?
I will deeply appreciate any comments.
Thank you very much in advance.
Kindest regards,
