Issue

When running the ONTAP command to expand the aggregate with more disks, the system shows an error preventing the disks from being added.

::> storage aggregate add-disks -aggregate <aggr_name> -diskcount <number_of_disks>
 
Error: command failed: Addition of disks would fail for aggregate <aggr_name> on node <node_name>
Reason: When starting a new raid_dp RAID group, the number of disks specified must be at least 3 for unmirrored aggregates and at least 6 for mirrored aggregates.
