they must be in the same zone in VSAN 1, as well as in VSAN 2. If they are not in the same zone, then
the hard-zoning ACL entries will prohibit pwwn1 from communicating with pwwn2.

OLTP_Backup
A zone corresponding to each active IVZ is automatically created in each edge VSAN specified in the
active IVZ. All pWWNs in the IVZ are members of these zones in each VSAN.
The zones are created automatically by the IVR process when an IVZS is activated. They are not stored
in a full zone set database and are lost when the switch reboots or when a new zone set is activated. The
IVR feature monitors these events and adds the zones corresponding to the active IVZS configuration
when a new zone set is activated. Like zone sets, IVR zone sets are also activated non-disruptively.
If pwwn1 and pwwn2 are in an IVZ in the current as well as the new IVZS then activation of the new
IVZS does not cause any traffic disruption between them.
