Clustered Data ONTAP 8.3
The following rules are enforced automatically when creating a disk-partitioned root aggregate:
- A RAID group cannot have more than one partition from the same disk.
- Partitioned and physical disks can be present together in the same aggregate, however, they must be in different RAID groups.
- The ONLY supported RAID type for aggregates containing root-data partitioned disks is RAID-DP. RAID4 is not supported.
The following error message is reported when attempting to change the RAID type:
cluster1::> aggr modify -aggregate aggr0 -raidtype raid4
Error: command failed: Failed to modify raidtype of aggregate "aggr0".
Reason: Change to raidtype RAID4 is not supported. Fields that were successfully modified: none
