Updating the worldwide port name for a new 5735 IOA
If you exchange a 5735 Fibre Channel input/output adapter (IOA), the IBM® external storage subsystem must be updated to use the worldwide port name (WWPN) of the new 5735 IOA. Any SAN hardware that uses the 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 by using the Hardware Service Manager in SST or DST to display details about the 5735 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 that is found on the tailstock label of the Fibre Channel IO adapter.
