Hi Bakunin,

From the HMC, I can list all the wwpn of lpar as below

Code:

yyy@xxx:~> lshwres -r virtualio --rsubtype fc --level lpar -m zzzzz -F lpar_name,wwpns --header --filter lpar_names=nnn
lpar_name,wwpns
xxx,"c050760671b1001e,c050760671b1001f"
xxx,"c050760671b1001c,c050760671b1001d"
xxx,"c050760671b1001a,c050760671b1001b"
xxx,"c050760671b10018,c050760671b10019"

ADDENDUM: in my introduction to FC networks i forgot to mention that new adapters need to be "logged in" to the network before they can be used and their WWPNs are recognised. If you have an LPAR without NPIV you can simply start the system and the FC adapters will be logged in automatically. But with NPIV and a boot disk from the SAN directly (and not via VIOS as a SCSI-disk) you need to take this into account when discovering the disks for the first time.

We use VIOS and the boot disk from the SAN directly. From VIOS, I can see the fcs is logged already

Code:

VFC client name:fcs3            VFC client DRC:U9117.MMD.06528F7-V17-C412

So strange we can see only 1 WWPN. Or only this WWPN is used?

I suspect it uses the zoning with type active-standby

NAME

       face - executable for the Framed Access Command Environment Interface

SYNOPSIS

       face [-i init_file] [-c command_file] [-a alias_file] [filename...]

DESCRIPTION

       The  Framed  Access  Command  Environment Interface (FACE) presents your files and file folders on the screen through a system of menus and
       forms if you are properly set up as a FACE user.

       filename must follow the naming convention Menu.xxx for a menu, Form.xxx for a form, and Text.xxx for a text file, where xxx is any  string
       that  conforms  to  the  UNIX   system  file  naming conventions. The Form and Menu Language Interpreter (FMLI) descriptor lifetime will be
       ignored for all frames opened by argument to face. These frames have a lifetime of immortal by default. If filename is not specified on the
       command line, the  FACE Menu will be opened along with those objects specified by the
        LOGINWIN environment variables. These variables are found in the user's .environ file.

OPTIONS

       The following options are supported:

       -a alias_file           Alias file

       -c command_file         Command file

       -i init_file            Initial file

OPERANDS

       The following operand is supported:

       filename        The full pathname of the file describing the object to be opened initially.

EXIT STATUS

       The face command will return a non-zero exit value if the user is not properly set up as a  FACE user.

FILES

       $HOME/pref/.environ
