If the partition condition needs fixing after a sort-order change, you can use alter table with the partition by option to repartition a table that has suspect partitions.
If the partition condition does not need fixing, you can use the reorg rebuild table command to rebuild the table, redistributing only the data rows among the partitions.
If the indexes as well as the partitions on a table are marked suspect, use partition by or reorg rebuild to fix both the suspect index and suspect partitions.
