The rebuild alarm tone functions differently. It remains ON during the rebuild. After the
rebuild completes, an alarm with a different tone sounds to signal that the rebuild is
complete. This is a one-time, non-repeating tone.

SAS/SATA Connector Pin-out
Signal names are with respect to the host; the device connected to the host reverses the
signal names. Transmit pins connect to receive pins on the other device. The SAS/SATA
connector is keyed at pin 1. These pin-outs for the serial ATA connector are not
compatible with the legacy PATA connector.
