ABSTRACT:
Provided are methods for borrow processing in storage pools. A plurality of physical volumes are allocated to a first storage pool. A determination is made whether the first storage pool has less than a threshold number of empty physical volumes. If the first storage pool has less than the threshold number of empty physical volumes, then at least one empty physical volume is borrowed to the first storage pool from a second storage pool.
