if you triple checked the zone and it looks good, next step i would reboot the system ( if it's not in production). If it's in production ..initiate some kind of scan (cfgmgr on AIX).
I am working on looking at hba logins on to VMAX FAs, I have configured zones on brocade with 1HBA and 2 FAs total 4 zones as follows.  zone1=hba1,7e0,7f0 zone2=hba2, 7e0, 7f0 zone3=hab3,7e0,7f0  on fabric_A, when i check for the hba that logged into FAs 7e0 and 7f0, 7f0 shows all the 3 hbas but 7e0 shows only 2 of 3 but shows the wwn of 7f0....how to see my 3rd hba on 7e0 ??   Thanks,
Fibre FA on VMAX shows another wwn of another FA.
