Hi Richard,

A tape from the storage pool without collocation was reclaimed of a
scratched volume, but the data from the client (now in the pool with
collocation) was reclaimed on the same tape. So the data still in the pool
without collocation.

Your second suggestion to use 'move data' (for example: move data 000001
stg=collocation), I think all clients on the volume 000001 are move to the
collocation storage pool and I want only move data from clients, which are
in the new storage pool with collocation.

Thanks for your answer,

Michael
