Notes about Spare Drives

If EZ mode is disabled (SW1:2 ON), all individual drives not configured as array members will be offered to the host adapter as separate units.

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 spare. 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 the array.
