Enter the rescan rate in minutes.
This tells the SM how often it should look for an available drive by rescanning the bus. Rescanning the
bus frequently can affect performance. If you have an EMP, the dynamic spare configuration will not
rescan the bus. The EMP will detect the new drive and tell the SM to rescan; the rescan rate you set here
will not affect the system.
The system confirms the change.

E.3 Managing the Spare Pool
The spare pool lets you have one or more disk drives available for the reconstruction of redundant arrays
(mirrored [RAID 1 and RAID 10] and parity [RAID 3, RAID 4, RAID 5, and RAID 50]). Once you assign a
drive to the spare pool, it is not available for use as an array member or as a dedicated spare.
Pool spares are available to both SMs. If a drive in an array on either SM fails, the SM can use a pool
spare to reconstruct the array.
If a pool spare is too small (smaller than an individual member in an array), the SM cannot use it.
