aggr mirror aggrname
[ -f ]
[ -n ]
[ -v victim_aggrname ]
[ -d disk1 [ disk2 … ] ]
Turns an unmirrored aggregate into a mirrored aggregate by adding a plex to it. The plex is either newlyformed from disks chosen from a spare pool, or, if the -v option is specified, is taken from another existing unmirrored aggregate. Aggregate aggrname must currently be unmirrored. Use aggr create to make a new, mirrored aggregate from scratch.
Disks may be specified explicitly using -d in the same way as with the aggr create and aggr add commands.
The number of disks indicated must match the number present on the existing aggregate. The disks specified are not permitted to span disk pools. This behavior can be overridden with the -f option. The -f option, in combination with -d, can also be used to force using disks that have a rotational speed that does not match that of the majority of existing disks in the aggregate.
If disks are not specified explicitly, then disks are automatically selected to match those in the aggregate’s existing plex.
The -v option can be used to join victim_aggrname back into aggrname to form a mirrored aggregate. The result is a mirrored aggregate named aggrname which is otherwise identical to aggrname before the operation.
Victim_aggrname is effectively destroyed. Victim_aggrname must have been previously mirrored with aggrname, and then separated via the aggr split command. Victim_aggrname must be offline. Combined with the -v option, the -f option can be used to join aggrname and victim_aggrname without prompting the user.
The -n option can be used to display the command that the system will execute without actually making any changes. This is useful for displaying the automatically selected disks, for example.
