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

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
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. FILES
