Maybe start over again. Your frame has 4 fibre channel adapters

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?

glupartialdisk

GLUPARTIALDISK(3G)														GLUPARTIALDISK(3G)

NAME

       gluPartialDisk - draw an arc of a disk

C SPECIFICATION

       void gluPartialDisk( GLUquadric* quad,
			    GLdouble inner,
			    GLdouble outer,
			    GLint slices,
			    GLint loops,
			    GLdouble start,
			    GLdouble sweep )

PARAMETERS

       quad    Specifies a quadrics object (created with gluNewQuadric).

       inner   Specifies the inner radius of the partial disk (can be 0).

       outer   Specifies the outer radius of the partial disk.

       slices  Specifies the number of subdivisions around the z axis.

       loops   Specifies the number of concentric rings about the origin into which the partial disk is subdivided.

       start   Specifies the starting angle, in degrees, of the disk portion.

       sweep   Specifies the sweep angle, in degrees, of the disk portion.

DESCRIPTION

       gluPartialDisk  renders	a partial disk on the z=0 plane. A partial disk is similar to a full disk, except that only the subset of the disk
       from start through start + sweep is included (where 0 degrees is along the +yaxis, 90 degrees along the +x axis, 180 degrees along  the	-y
       axis, and 270 degrees along the -x axis).

       The partial disk has a radius of outer, and contains a concentric circular hole with a radius of inner. If inner is 0, then no hole is gen-
       erated. The partial disk is subdivided around the z axis into slices (like pizza slices), and also about the z axis into rings  (as  speci-
       fied by slices and loops, respectively).

       With  respect  to orientation, the +z side of the partial disk is considered to be outside (see gluQuadricOrientation).	This means that if
       the orientation is set to GLU_OUTSIDE, then any normals generated point along the +z axis. Otherwise, they point along the -z axis.

       If texturing is turned on (with gluQuadricTexture), texture coordinates are generated linearly such that where r=outer, the value at (r, 0,
       0) is (1.0, 0.5), at (0, r, 0) it is (0.5, 1.0), at (-r, 0, 0) it is (0.0, 0.5), and at (0, -r, 0) it is (0.5, 0.0).
