Creating a mirrored aggregate or traditional volume, where Data ONTAP selects the disks

To create a mirrored aggregate or traditional volume by letting Data ONTAP select the disks used, complete the following step.

Step

1. Enter the following command:{ aggr | vol } create { aggrname | volname } -m ndisks[@disk-size]

   aggrname is the name for the new aggregate.

   volname is the name for the new traditional volume (without the /vol/prefix).

   -m specifies a mirrored aggregate or traditional volume to Data ONTAP.

   ndisks is the number of disks to use; must be at least 4 and an even number. Even numbers are required because half of the disks specified by ndisks go to one plex from one disk pool, and the other half go to the other plex from another disk pool.

   disk-size specifies the disk capacity, in gigabytes. There must be enough disks of this size available to both disk pools if you use this option.

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

   Example

   The following command creates a mirrored aggregate that has two plexes, each plex containing three disks.aggr create aggrA -m 6
