Adding disks to a mirrored aggregate, where Data ONTAP selects the disks

When you add disks to a mirrored aggregate, you can allow Data ONTAP to select the disks.


  1. Enter the following command:aggr add aggrname ndisks[@disk-size]
    aggrname is the name of the aggregate to which you are adding disks or array LUNs.

    ndisks is the number of disks or array LUNs to use. This number must be an even number, because half these disks or array LUNs must be in each pool.

    disk-size specifies the disk or array LUN capacity, in gigabytes.

    Note: If you use the disk-size option, you should first determine the size of spare disks or array LUNs in the pools using the aggr status -r or vol status -r command.
