Firstly, I followed the "Adding or replacing the mezzanine card" to change our 10G Ethernet mezzanine cards with the new FC X1150A-R6 cards.

I went into maintenance mode and test the newly installed hardware which was OK.
I did not have to change the mezzaning fc ports from target mode to initiator mode as they were already configured so
C1NETAPP-VIRTU> ucadmin show
Current Current Pending Pending Admin
Adapter Mode Type Mode Type Status
------- ------- --------- ------- --------- -------
1a fc initiator - - Online
1b fc initiator - - Online
Secondly, I set a unique ID for each of the 4 DS14mk2 shelves (4,5,6 and 7 in my case) and rebooted them.
Then I used the below guide to connect the DS14mk2 FC Shelves to the mezzanine card (stack the disk shelves with the FAS224x system)

It's worth noting that these FC shelves were already used in production with another system. I was 100% sure that the stacking was correct but sysconfig -a or fcadmin device_map would not return me all the newly disks. I was able to detect this little issue by using a storage show which showed all disks and their respective owners, in the present case it showed that the old system still owning these FC disks. After that, I issued disk assign [DiskID] -s unowned -f on these disks, and the auto assign option took care to assign the newly 48 disks to my both nodes.
Aggregates and volumes creation went flawless.
I would like to thank you for all your availabiliy and assistance that you provided us with. Much apreciated.
