Re: describe WWN and WWP

The world wide name (WWN) is a unique name for SAN devices. A node (e.g. a HBA) has a node name and 1 or more port names, one for each port.

Hope this helps!
Regards
Torsten.

Re: describe WWN and WWP

As said in the link above, the WWN is the equivalent of the MAC address of a NIC, "built-in" into the HBA.

Hope this helps!
