All R1 host updates are replicated to the R2 device. When data is not actually copied is on an initial synchronization AND both the R1 and R2 tracks are marked as never previously been written (both therefore containing all 0x'00'). The first host update to a track removes the never previously written attribute.
Hi everyone,  Does someone know how SRDF copies data from R1 to R2? Is it bit by bit? Does it copy empty spaces as well to R2?  Thanks for responses!
