Each Fibre Channel adapter on the nodes has a unique World Wide Number (Identified in ESS Specialist as World Wide Port Number - WWPN).
When creating a new host with ESS Specialist, select the appropriate WWPN in a scroll list. If you don't see this WWPN, ensure the following:
The link is correct. You should see the red laser light emitted by the host adapter on the fiber connected to the Storage Area Network - SAN (FC switch).
The FC adapters on the nodes and the ESS have the proper link type value of point-to-point or arbitrated loop. If you are unsure about your network topology, leave the default, which is arbitrated loop.
The command cfgmgr -vsl fcs0 has been run on the nodes.
