The administrator replaces the failed disk with a new disk of the same geometry. Depending on the system model, the disk replacement may require that the system be powered down. The replacement disk is then partitioned identically to the mirror, and state database replicas are copied onto the replacement disk. Finally, the metareplace command copies that data from the mirror to the replacement disk, restoring redundancy to the system.
