Field descriptions

Number of Extents Not Referenced: Specifies the number of data extents that are not referenced in the directory-container storage pool. You can delete the data extents if they are not referenced again within the reuse delay period that is specified on the DEFINE STGPOOL command.
Number of Extents Eligible for Deletion: Specifies the number of data extents that can be deleted from the storage pool. The data extents exceed the reuse delay period that is specified on the DEFINE STGPOOL command.
