Forcibly adding disks to aggregates

You might want to override some of the restrictions on what disks can be added to an aggregate if you don't have disks of the right speed or enough disks in the correct pool. You use the aggr add -f command to accomplish this.

Considerations

If you want to add to an aggregate a disk that is not an optimal choice or that requires confirmation, you can use the aggr add -f command. This can be useful in the following situations:

You need to add disks from two different spare disk pools to a mirrored aggregate.
You need to add disks of a different speed than that of existing disks in the aggregate.
You need to add disks to a RAID group other than the last RAID group.
