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.

Without going into an in depth look at your system, are you sure you are presenting disks up from the VIO? 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:

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?

NAME

       fp - Sun Fibre Channel port driver

DESCRIPTION

       The  fp	driver	is a Sun fibre channel nexus driver that enables fibre channel topology discovery, device discovery, fibre channel adapter
       port management and other capabilities through well-defined fibre channel adapter driver interfaces.

       The fp driver requires the presence of a fabric name server in fabric and public loop topologies to discover fibre channel devices. In pri-
       vate  loop  topologies,	the  driver discovers devices by performing PLOGI to all valid AL_PAs, provided that devices do not participate in
       LIRP and LILP stages of loop initialization.

CONFIGURATION

       The fp driver is configured by defining	properties in the fp.conf file. The fp driver supports the following properties:

   mpxio-disable
       Solaris I/O multipathing is enabled or disabled on fibre channel devices with the  mpxio-disable  property.  Specifying	mpxio-disable="no"
       activates I/O multipathing, while mpxio-disable="yes" disables the feature.

       Solaris	I/O  multipathing  may be enabled or disabled on a per port basis. Per port settings override the global setting for the specified
       ports. The following example shows how to disable multipathing on port 0 whose parent is /pci@8,600000/SUNW,qlc@4:

       name="fp"    parent="/pci@8,600000/SUNW,qlc@4"	 port=0
       mpxio-disable="yes";

   manual_configuration_only
       Automatic configuration of SCSI devices in the fabric is enabled by default and thus allows all devices discovered in the SAN zone  to	be
       enumerated   in	the  kernel's  device tree automatically. The manual_configuration_only property may be configured  to disable the default
       behavior and force the manual configuration of the devices in the SAN. Specifying manual_configuration_only=1 disables the  automatic  con-
       figuration of devices.
