Converting from RAID-DP to RAID-TEC

If you want the added protection of triple-parity, you can convert from RAID-DP to RAID-TEC. RAID-TEC is recommended if the size of the disks used in your aggregate is greater than 4 TiB.

Before you begin

The aggregate that is to be converted must have a minimum of six disks.

About this task

Hard disk drive (HDD) aggregates can be converted from RAID-DP to RAID-TEC. This includes HDD tiers in Flash Pool aggregates.


  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-DP to RAID-TEC: storage aggregate modify -aggregate aggregate_name -raidtype raid_tec
  3. Verify that the aggregate RAID policy is RAID-TEC: storage aggregate show aggregate_name
