VIOS - fibre adapters not seeing luns

Hi guys,

I've been trying to tackle this issue for days and I'm stumped. Hopefully someone can give more light on what else I can do.

I have a p7 series box, with dual VIOS and 10 lpars and everything was working fine until I had to move the box to another location in the data centre. Ensured I labelled where each cable went etc.

Upon powering on the p7 server, it came up fine into standby mode. Then powered on the system. After that, I then powered on the VIOS (Primary) server and that came up fine and booted into the OS. (Each VIOS server has 2 x dual ports dedicated fibre adapters) I then proceeded to boot each lpar successfully. Now, when I ran lspath on VIOS (Primary) it showed that the second adapter has failed path. I tried to re-enable it to no success. I thought I'd continue with VIOS (Secondary) and continue along, to my suprise, no luns were accessible to the server. I even tried to go to SMS Menu to use the SAN Zone support, and Open firmware prompt for ioinfo and no luns were displaying. (I am using SCSI adapters for the luns)

The list below is what I have tried and unsuccessful.
1 - have changed over the fibre cables to the adapter and no success
2 - have bypassed the fibre patch panel and directly to the fibre switch and no success
3 - confirmed we can see light coming through the fibre cables
4 - Changed switched ports on the fibre adapters
5 - wrap plug test and no success
6 - Used the fibre cable that is plugged into the working fibre adapter and used in the fibre adapter that has issues and still no success.
7 - I have confirmed that I can see the fibre adapters as available on the VIOS server
8 - I have removed the fibre adapters from the system and re configured them
9 - I have shutdown the system completely, removed power and reattached power and started up the system and no success
10 - I have physically removed the fibre adapters and reseated them
11 - I have provided IBM with a 'snap' which is the system configuration of the VIOS server - so far hardware support can't find any fault.
12 - I have screenshot my VIOS configuration profile to IBM - no issues here
13 - I have ran an exe program from IBM to determine transmit and receive and noise on the port and the ones not working don't output any information.
14 - I have moved the fibre adapters from the VIOS server to another LPAR and still have the same issues.
15 - On the back on the server, I can see there is power to the adapters with green flash lights, but no link activity.
16 - I have checked with IBM documentation that Green LED slow flash and no Yellow LED indicates - Normal, link inactive or not started.

Any input would be appreciated. Thanks.

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
