This section describes the procedures for recovering from a primary site failure or a P-VOL failure (LDEV blockade) at the primary site using examples.
GAD pairs might be created between the primary and secondary sites that configure GAD as follows:
- A P-VOL of a GAD pair is at site 1 and a S-VOL is at site 2.
- A P-VOL of a different GAD pair is at site 2 and a S-VOL is at site 1.
In this case, recover from a failure at the secondary site. For more information, see Recovering from secondary site and S-VOL failures (GAD+UR).
