If you have exchanged a 2766, 2787, 280E, 5735, 576B, or 5774 Fibre Channel IOA, the IBM® external storage subsystem must be updated to use the worldwide port name (WWPN) of the new 2766, 2787, 280E, 5735, 576B, or 5774 IOA. Any SAN hardware using WWPN zoning might also need updating.
For instructions on how to update the external storage subsystem or SAN hardware configurations, see the documentation for those systems.
The WWPN for the Fibre Channel IOA can be found using the Hardware Service Manager in SST or DST. Display detail on the 2766, 2787, 280E, 5735, 576B, or 5774 IOA Logical Hardware Resource information, and use the port worldwide name field.
The 16-digit WWPN can also be determined by appending the digits "1000" to the beginning of the 12-digit IEEE address found on the tailstock label of the Fibre Channel IOA.
