After studing your recent post, I tried the following:

1. Separated Controller A, port 2 of Protected storage and Controller A, por2 of recovery storage into one zone and Controller B, p2 of protected storage and Controller B, port2 of recovery storage into a different zone. Both zones are on the same VSAN.

2. Above resulted in inability to set up a mirrored pair. I get an error message - saying can not esablish communication to the other side of a mirrored pair

Therefore, I had to combied all for FC ports in (1) into the same zone.

I understnd that may have created a problem of a controller failover I've seen, but the system still works OK .

I tested failover sevaral times and everything looks good. Thanks again for your very usefull comments.
