Managing the Spare Pool
The spare pool allows the user to have one or more disk drives available for the reconstruction
of redundant arrays (Mirrored and Parity). Once a drive is assigned to the spare pool, it is no
longer available for use as an array member or as a dedicated spare. If a pool spare is too
small (not enough capacity to replace the smallest member in the array), the controller cannot
use it.
Adding a Spare to the Spare Pool
This function allows the user to add up to eight (8) drives to the spare pool to reconstruct any
critical array on the controller. After an array has started using a pool spare, other critical
arrays are prevented from using it. If a pool spare is too small (not enough capacity to replace
the smallest member in the array), the controller cannot use it.
To add a pool spare:
1. Select Pool Spare Menu from the System Menu and press Enter.
The Pool Spare Menu should now display (Figure 53).
2. Select Add Pool Spare and press Enter.
The Select Drives screen should now display (Figure 54).
