This is because you manually registered the initiators instead of using navisphere/unisphere agent on the host. If you install the agent you can specify the IP addresses of the 2 storage arrays and the host will automatically register. Not sure what type of OS you are using but ESX does not have an agent but most of the other OSes do.  The agent install files can be found under Support -> Software Downloads -> Downloads J-O -> Navisphere Server Software or Downloads T-Z -> Unisphere Server Software.
Hi, I have two storage (cx4-120:Navisphere 6.29.6.0.64 & cx3-10c:Navisphere 6.24.3.1.0) cx4 have one hba connected to swicthA1 (brocade 300) and the other hba to switchA (brocade 200E) cx3 have one hba connected to swicthB1 (brocade 300) and the other hba to switchB (brocade 200E) switchA1 is connected with switchB1 via ISL (one FC cable) switchA is connected with switchB via ISL (one FC cable) All the switch have a full fabric licence and ISLs seems to work correctly. serverA1 hbaDX, serverB1 hbaDX, serverC1 hbaDX are connected with switchA1 serverA1 hbaSX, serverB1 hbaSX, serverC1 hbaSX are connected with switchA serverA hbaDX, serverB hbaDX, serverC hbaDX are connected with switchB1 serverA hbaSX, serverB hbaSX, serverC hbaSX are connected with switchB Zones are created between each server hba and each storage hba. On navisphere I can see on cx4 in the Hosts folder serverA1, serverB1, serverC1 correctly, then three strange "double" WWN. The firsts 8 digit couples doesn't correspond to any WWN switches port, the seconds 8 digit couples are the serverA, serverB and serverC WWNs. And so on cx3 for the other servers. Each host with "double" WWN is classified as Unknown; Fibre; Host Agent not reachable. Surely I missed something! Do the zone for the "remote servers" (ex. serverA hbaDX, serverB hbaDX, serverC hbaDX on switch B1 as regards cx4) need a particular configuration? Do the switch ports need a particular configuration? What else?  Thanks for any help  Vale et valete ZAMPO
