- -fdevice
- Device to use. Default to /dev/amr0.

- Report status of a logical drive.
- -pdriveno
- Report status of a physical drive.
- -sbusno
- Report status of all physical drives on the specified bus.
- -sbusno:driveno
- Report status of the specified physical drive on the specified bus.
- -tmicroseconds
- Delay between retries for a command.
