Add disks function in ONTAP System Manager is missing
Applies to
- ONTAP System Manager 9.7 and later
- RAID groups belonging to the aggregate are nearly full
Answer
There is an algorithm in ONTAP that purposely avoids adding disks to prevent creating a "hotspot" on the aggregate.
- There are no such restrictions while adding the spares from CLI.
- Users can add spare disks using the CLI or create a larger raid group on the aggregate by utilizing additional spare disks through ONTAP System Manager.
