Abstract
An apparatus, program product and method initialize a redundant memory device by delaying the switchover of non-initialization fetch operations from a failed memory device to the redundant memory device until after initialization of the redundant memory device is complete. Consequently, during initialization, the non-initialization fetch operations are directed to the failed memory device, while non-initialization store operations are directed to the redundant device.
