Maybe start over again. Your frame has 4 fibre channel adapters
you have allocated two to the vio and 2 to an lpar.
And now what - you are trying to map the adapters from the lpar via vio to another lpar?
With NPIV you map to a virtual wwpn, while when you zone to a physical adapter, you map to the physical wwpn. So I do not understand how removing a fibre channel adapter would show anything ?
Hi Zmaus,
The point 1 and 2 are correct. On the lpar I can see the LUN with 2 physical fibre.
Now I would like to use 1 more virtual fiber adapter to assign to lpar from VIO. And zoning virtual wwpn to the same LUN.
If everything is correct, I can see the LUN with 2 physical fibre adapters + 1 virtual fibre adapter.

Are you sure your lpar has virtual adapters presented up from the VIO? I mean, the whole point of running a VIO is so that takes all (or most) of your adapters so you can present them to the lpars as part of the virtualization layer. There should be very few instances where you need physical adapters assigned the a lpar running under a VIO.
Also from ioinfo from the openfirmware, its common to see that message. openfirmware is not aware so to speak to anything not apart of the system.
IF I manage to find time, I will show you how one of my environments are setup. Currently a lot of cruft on my plate that I must address first. Also, you should note that I'm not using NPIV, and my setup may not be the 'IBM recommended' way.
In the meantime, here's some handy links:

And since you are using npiv:

Hi RecoveryOne,
I'm checking the links you shared. From my side, I presented the virtual adapter to both VIO and lpar. With the lsmap I can see the client has logged in the fibre channel, from the SAN switch, checked with storage team, I can see the virtual wwpn. Further check with them, I can be quite sure the zoning & LUN masking works properly, that virtual WWPN is the same zone member with physical wwpn. Removing physical wwpn, make the link missing, means that the virtual wwpn(which is same zone) should see the LUN as well.
A bit curious, if you did not use NPIV, so which method you are using now?
