The format and content of the fibre-channel port identifier
are determined by the manufacturer of the link control facility for
the applicable fibre-channel port. The identifier is an eight-byte
field, which the fibre-channel protocols use to uniquely identify
the fibre-channel port.
The WWPN consists of 16 hexadecimal characters (0
- 9 and A - F). The
SAN Volume Controller uses
it to uniquely identify the fibre-channel HBA that is installed in
your host system. The
SAN Volume Controller automatically
finds the WWPN for your host fibre-channel HBA when you attach your
host system to the
SAN Volume Controller.
Note: If
your host uses more than one fibre-channel HBA to connect to your SAN Volume Controller,
you must add multiple entries to the host list for this host. You
must add one for each fibre-channel HBA. Each HBA will have a unique
WWPN.
