Applies to
- ONTAP 9.x
- Advanced Drive Paritioning (ADP)
- FAS Systems
- All Flash FAS (AFF)
Issue
- AGGR with both partitioned and non-partitioned.
- After upgrading ONTAP, the system automatically partitions the spare disk on the whole drives.

- As a result, there is no suitable spare disk available for AGGR using an unpartitioned whole disk.
