Hmm - actually - If you're using NPIV, you've defined pseudo WWPNs to be assigned to the FCP subchannels and that gets stored on the SE ( thinkpad on the side ) If you lose that FCP port and Service replaces the adapter, then once you bring the card back online and get the switch talking to it ( the NPIV config on the switch side of the link ) you should be back in business. The SE will write the NPIV config back onto the channel when it comes online. You shouldn't have to change any Fabric Zoning in the switches or LUN Masking in the storage subsystem. I'll have to check that it actually works this way - but this could be a major reason to use NPIV in and of itself. It could conceivably make management easier in addition to security and access control. -- Jay Brenneman
