•Enter a polling interval (1 to 1440 minutes) in SMART Polling Interval field.

•Check the Coercion Enabled box to enable disk drive capacity coercion.

When disk drives of different capacities are used in the same array, coercion reduces the usable capacity of the larger disk drive(s) in order to match the smallest capacity drive.

•Select a coercion method from the Coercion Method dropdown menu. The choices are:

GB Truncate – (Default) Reduces the useful capacity to the nearest 1,000,000,000 byte boundary. 10GB Truncate – Reduces the useful capacity to the nearest 10,000,000,000 byte boundary.

Group Rounding – Uses an algorithm to determine how much to truncate. Results in the maximum amount of usable drive capacity.

Table Rounding – Applies a predefined table to determine how much to truncate.

•Enter a time interval (1 to 12 seconds) in the Write Back Cache Flush Interval field.

•Enter a time interval (15 to 255 seconds) in the Enclosure Polling Interval field.
