The BZ switch is used to silence the audible alarm buzzer. The OFF position
permits the audible alarm, and the ON position silences the audible alar\

To create an array with one or more spares, set or modify the RAID mode using fewer than 5 members, while the spares are disconnected from the Port Multiplier. When EZ mode is enabled, individual drives connected when an array is present are considered spare. Spare drives must be equal to or larger in size than the smallest member\ . When any type of array is defined, individual units will be considered s\ pare. RAID 0 and LARGE arrays are not fault-tolerant and spare drives will not\ be useful; therefore, disabling EZ for these arrays is recommended. When a spare drive is present and a fault-tolerant RAID (1, 10, 3, or 5\ ) is defined, EZ mode will automatically rebuild any available spares into th\ e array.
