The DS6000™ uses a worldwide port name (WWPN) to uniquely identify a host port that is connected to a storage unit. The WWPN consists of exactly 16 hexadecimal characters (0 - 9 and A - F).
The DS6000 automatically finds the WWPN for its ports on its host adapters when you attach your host system. You must identify the unique WWPN of each port on your host system that is attached to a DS6000. You use those WWPNs when you configure a host attachment either through the DS Storage Manager or the DS CLI.
You can manually locate a unique worldwide port name for your host ports by performing the steps outlined in the following references:
