Dell SRDF Introduction
Recovery for a large number of invalid tracks
If the R2 devices have handled production processing for a long period of time, there may be a large number of invalid tracks owed to the R1 devices. SRDF control software can resynchronize the R1 and R2 devices while the secondary host continues production processing. Once there is a relatively small number of invalid tracks owed to the R1 devices, the failback process can take place.
