Which command creates a new SyncMirror aggregate, letting Data ONTAP select the disk drives?

• A. aggr create aggrX -d 12
• B. aggr create aggrX -m 12
• C. aggr mirror aggrX -m 12
• D. aggr mirror aggrX -n 12

Answer: (B)

Creating a SyncMirror aggregate means building a two-copy (two-way) mirror of data across multiple disks, with Data ONTAP managing where those copies reside. To have ONTAP pick the drives automatically, you use the aggregate creation command with the mirror option. The -m flag signals that this is a SyncMirror and the number you provide after it tells ONTAP how many disks to include in the mirror. With this approach, Data ONTAP selects the specific disks itself, rather than you listing exact drives (-d would require you to specify disks manually). The other forms shown use an invalid creation syntax or try to specify disks explicitly, so they don’t create a new SyncMirror aggregate with automatic disk selection.
