You check the new Shelf on a other System? Which System?
Take options 5)
Please take Point 5) from special boot Menue and type:
"disk show -v" it show you maybe unowned Disks, with disk assign all you can assign them to the host and you can built up a new root with 4a) on next boot.
But when you remove the Disks to add them at your FAS2040 you have to remove the Ownership from the Disks.
When you still see no Disks, try
"fcadmin config" that 0a is configured as initiator and not as target.
Adapter Type State Status
---------------------------------------------------
0a initiator CONFIGURED. offline
0b initiator CONFIGURED. offline
0c initiator CONFIGURED. offline
0d initiator CONFIGURED. offline
when there is target and a other port is already initiator change the port, or
fcadmin config -t initiator 0a (maybe it's needed to set it offline, then fcadmin config -d 0a)
