5.2.16 Looking for MAC/WWN/GUID and SAS addresses
The customer needs to know the new address of the controller:
– When replacing the system board with an onboard LAN controller

Different controllers send different addresses:
– LAN controller: MAC (Media Access Control) address
– Fibre channel controller: WWN (World Wide Name) address
– Infiniband/Omni-Path controller: GUID (Globally Unique IDentifier) address
– SAS controller: SAS (Serial Attached SCSI) address
