Answer

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

cluster1::>
