Each HBA is shipped with several numbers clearly marked on the board. These numbers indicate the following:
IEEE Address
World Wide Name (WWN)
Serial number
The IEEE address is a unique 64-bit identifier that you use when configuring your system. The FC industry uses the World Wide Name (WWN) derived from the IEEE address for FC connectivity. If the adapter has two ports, there are two IEEE addresses and two WWNs. Use the serial number when communicating with Oracle Service.
Refer to Observing ESD and Handling Precautions.
To see if your system supports hot plugging/hot swapping of PCIe adapter cards, refer to your system documentation.
