Troubleshooting NPIV
If NPIV is not working as expected, there are several things you can check.
First, check whether the FCP channel supports NPIV.
If the FCP channel supports NPIV, check the error messages to find more details about what is wrong.
If NPIV is enabled on an FCP channel that is
used by zfcp, some NPIV-specific messages may be logged on the system
console and in /var/log/messages. The messages might help to understand the cause of the
link down problem, for example on cable disconnect:
zfcp.7d6999: 0.0.c419: There is no light signal from the local fibre channel cableWhen the link is restored, you might get the following message:
zfcp.ac341f: 0.0.c419: The local link has been restored
