Grigori,

Your process below works; I would have done the same as Christian
Svensson that is migrating all the data off of the Disk storage pool to
the next storage pool (what hierarchy do you have in your environment:
Disk -> VTL -> Tape  or Disk -> Tape?? ). Depending on the number of
tape drives you have available you could increase the migprocress
parameter to push the data off of the DISK pool to the next stgpool
faster; you should also run the migrations outside the backup interval.

You may still have to change any references of the DISK pool in the tape
copy pools before being able to delete the DISK pool itself. You could
update all the previous DISK pool reference once you define and rename
the FILE storage pool to the old DISK pool name.

Subject: [ADSM-L] 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,
