Reduce Storage Pool

Use this page to reduce the size of the selected storage pool. If you select a Volume Group-based storage pool, you can remove physical volumes from it. This makes the physical volumes available for direct assignment to logical partitions or for assignment to other storage pools. If you select a file-based storage pool, the storage pool is deleted and the space that was allocated to it is returned to its parent storage pool.

You can remove a physical volume from a storage pool only if the physical volume does not contain any virtual disk information on it. To continue, you must either delete the virtual disks that are on the physical volumes or use the migratepv command in the command line interface to move the virtual disk information from the physical volume.
