Mirroring is the process of replicating a dbspace for the purpose of reducing the risk of data loss in the event of a hardware failure. When mirroring is in place, both the primary and the mirror chunks are written to automatically. If a hardware failure causes the primary chunk to be inaccessible, Informix automatically reads from the mirror chunk.
