thanks John --- for you valuable time and help.. but what i can in first line on 124 page is applicable for the 2 different target array. i need to add two target on the same array for one R1.
Concurrent SRDF is for the purpose of a single R1 device going go multiple target arrays.
Since you already have the data on the target array, why do you think you need it twice? You can always snap/clone the R2 device to make a point-in-time copy of it.
