Begin by checking for faults with the adapter itself or its configuration.  For example, does the command syminq hba -fibre return any Unknown fields values (e.g. model, firmware, etc.), or is the HBA Name incorrect in the output?  Or does the lsattr -El return no value for scsi_id?  If so, run the cfgmgr command on the affected host and check that all the jumpers on the adapter are set correctly.  (see Primus article for emc107603)  If any such problems are eliminated, then to investigate further into your ECC infrastructure, please provide more details such as:  Kind Regards, Louie Cavaliere EMC Global Support.
I have a AIX server with two hba's.I see both the hba's are logged in from the switch end.But when checked in ECC I can see only one hba wwn under unidentified ports and could not see the other wwn.I have done re-discover as well but no luck.
Not able to see the wwn in ECC
