Converting RAID-TEC to RAID-DP

If you reduce the size of your aggregate and no longer need triple parity, you can convert your RAID policy from RAID-TEC to RAID-DP and reduce the number of disks you need for RAID parity.

About this task

The maximum RAID group size for RAID-TEC is larger than the maximum RAID group size for RAID-DP. If the largest RAID-TEC group size is not within the RAID-DP limits, you cannot convert to RAID-DP.


  1. Verify that the aggregate is online and has a minimum of six disks: storage aggregate show-status -aggregate aggregate_name
  2. Convert the aggregate from RAID-TEC to RAID-DP: storage aggregate modify -aggregate aggregate_name -raidtype raid_dp
  3. Verify that the aggregate RAID policy is RAID-DP: storage aggregate show aggregate_name
