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.

NAME

       scsimgr_fcd - Fibre Channel interface driver fcd plug-in for scsimgr

DESCRIPTION

       The  Fibre  Channel interface driver plug-in for implements management operations specific to fibre channel HBA controllers bound to driver
       is the native HP-UX Fibre Channel interface driver that manages fibre channel devices.

       The plug-in handles the following operations for driver

	  o	 Get, set and save per driver instance attributes.

   Commands
       The user can explicitly send the following commands to the driver plug-in by  specifying  the  instance#>  HBA  controller  hardware  path>
       instance#> option:

	  Displays information on attributes.

	  Saves value of attributes in a persistent store.

	  Sets values of attributes.

       Refer to scsimgr(1M) for the syntax of these commands.

       automatically invokes the plug-in to perform the driver specific part of the operation when the operation applies to per driver instances.

   Attributes
       The following table lists driver specific attributes.  For details on the concept of attributes refer to scsimgr(1M).

       Note: The following conventions are used:

	  o RO is Read Only.

	  o RW is Read Write.

	  o string is an array of characters.

       ---------------------------------------------------------------------
       Object	   Attribute Name  RO/RW  Type	  Description
       ---------------------------------------------------------------------
       Controller  sym_port_name   RW	  string  Symbolic  Port  Name	for
						  fibre  channel  HBA  con-
						  troller
						  Default:	     <host-
						  name>_fcd<instance#>
       ---------------------------------------------------------------------
		   sym_node_name   RW	  string  Symbolic  Node  Name	for
						  fibre  channel  HBA  con-
						  troller
						  Default:   <hostname>_HP-
						  UX_<os release version>
       ---------------------------------------------------------------------

EXAMPLES

       Display all attributes for HBA controller with DSF /dev/fcd1:

       Get HBA controller symbolic port name for DSF /dev/fcd1:

       Get HBA controller symbolic node name for hardware path 0/2/1/0:

       Set HBA controller symbolic port name for DSF /dev/fcd1 to fcd1_port:

       Set HBA controller symbolic node name for class fc and instance 8 to fcd1_node:

       Save HBA controller symbolic port name for DSF /dev/fcd1 as fcd1_port:

       Save HBA controller symbolic node name for hardware path 0/2/1/0 as fcd1_node:
