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)

To create a SyncMirror (mirrored) aggregate and have Data ONTAP pick the drives, use the aggregate creation command with the -m option. The -m flag tells ONTAP to build a mirrored aggregate, letting the system automatically select which disks to include. The number you pass indicates how many disks will be part of the aggregate, and ONTAP will distribute them into two plexes for the mirror. Choosing the -d option would require you to specify disks yourself, which means you’re not letting the OS select drives. The other form shown isn’t the standard way to create a SyncMirror in this context, since -m with aggr create is the correct, supported method for automatic drive selection.
