Abstract: Provided are a method, system, and program for managing data in storage units. Storage pool information indicates an assignment of a plurality of storage units to a plurality of storage pools, wherein each pool is assigned zero or more storage units, wherein data associated with one storage pool is stored in a storage unit assigned to the storage pool, wherein the storage pool information for each pool indicates a threshold and target storage pool, and wherein the target storage pool is capable of being different from the storage pool. One storage unit associated with a source storage pool is selected and a determination is made of the threshold from the storage pool information for the source storage pool. A determination is made of whether the selected storage unit satisfies the determined threshold and if the selected storage unit satisfies the determined threshold, then a target storage unit in the target storage pool is selected if the storage pool information for the source storage pool indicates a target storage pool different from the source storage pool. Data from the selected storage unit is copied to the selected target storage unit.

Abstract: A method and apparatus for maintaining information in one or more virtual volume aggregates comprising a plurality of virtual volumes. The method maintains a plurality of virtual volumes in a first information storage medium, and forms one or more virtual volume aggregates, where each of the of virtual volumes is assigned to one of the virtual volume aggregates. The method further provides a plurality of second information storage media. The method then identifies the least recently used virtual volume, and writes the virtual volume aggregate comprising that least recently used virtual volume to one or more second information storage media. Thereafter, the method determines if space is required on said first information storage medium. If space is required on said first information storage medium, the method selects the virtual volume aggregate comprising the least recently used virtual volume and removes from said first information storage medium each virtual volume in that selected virtual volume aggregate that has been written to one or more second information storage media.

Abstract: Information is maintained in one or more virtual volume aggregates comprisin g a plurality of virtual volumes. A plurality of virtual volumes is maintained in a first information storage medium, and forms one or more virtual volume aggregates, where each of the of virtual volumes is assigned to one of the virtual volume aggregates. The method further provides a plurality of second information storage media. The method then identifies the least recently use d virtual volume, and writes the virtual volume aggregate comprising that leas t recently used virtual volume to one or more second information storage media . Thereafter, the method determines if space is required on said first information storage medium. If space is required on said first information storage medium, the method selects the virtual volume aggregate comprising t he least recently used virtual volume and removes from said first information storage medium each virtual volume in that selected virtual volume aggregate that has been written to one or more second information storage media.
