Site A is TC P-VOL and Site B is S-VOL, both storages are USPV. Suppose we have completed following DR testing,
1) pairsplit -g xxx -rw at Site A
2) data changed on Site B S-VOL
3) running pairresync -g xxx -swaps on Site B to resync the blocks from B to A
After completing above steps, the P and S vols should be switched, P-VOL at Site B and S-VOL at Site A, and pair status is in 'PAIR'.
Now we want to failback P-VOL as origianl - P-VOL at Site A and S-VOL at Site B. I understand I can run 'horctakeover' at Site A. My question is can i run 'pairresync -swapp' at Site A to achieve this as well? if yes what difference from 'horctakeover' and 'pairresync -swapp'?
