3PAR doesn't see ESX 4 WWNs



we have a strange problem with one 3PAR implementation. 3PAR doesn't see ESX 4 host WWNs so we can't add ESX 4 hosts and present LUNs. It is strange because in the same deployment 3PAR sees Hyper-V 3.0 hosts without any problems and we can present LUNs to Hyper-V servers.


On SAN switch we can SEE WWNs on all ports (ESX hosts, 3PAR ports, Hyper-V hosts, old EVA ports).


We are sure zoning is configured correctly.


Any idea what could be wrong?


Thank you!


Best wishes,

Re: 3PAR doesn't see ESX 4 WWNs

I assume you are creating the host definition and trying to choose the host from a list of available WWN's?


What is the 3par model and Inform level?


Also, information from the hosts, HBA type, HBA driver, HA firmware....etc.


Switch type, model and FOS/NOS.


If zoning and physical connectivty is confirmed, then next step is  to check that we are dealing with a configuration that meets interoperability requirements.
