Hello TSM'rs

I have a question. Here's my senario, We backup to disk. Then Migrate to
tape once the backups complete.
I have a single drive tape.
the disk capacity is not enough to create another stgpool.
I want to execute the processes of space reclamation to the tapes.
Do I have some risk if it emigrates again from the tapepool to the diskpool
for tapes with 2% use?
That cautions should take?

your assistance is greatly appreciated.
Thanks,
