Convert from RAID-TEC to RAID-DP

If you reduce the size of your local tier (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.

What you'll need

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.

About this task

To understand the implications of converting between RAID types, refer to the parameters for the storage aggregate modify command.

Steps

  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
