Beschreibung
Zusammenfassung:	The invention provides a three-strip state conversion method which includes the steps that the states of three strips are changed, and the states of the three strips are used for indicating the current logic strip and the position relation of the logic strip; an erasure correcting code bitmap is made to indicate data blocks, for forming an erasure correcting code strip, at the position of the changed erasure correcting code strip and the position of a mirror strip. According to the three-strip state conversion method, the system expenses caused by data migration are lowered, and the performance of a three-strip system is improved.
