They take fibre channel disks, not SATA or SAS, and provide a FC interface to one or more host systems (initiators in storage parlance). Since they're just passing access through they'll support any disk that supports the same physical ...

You may be able to overwrite this firmware with stock firmware from the drives' OEM, but that may still not work, depending on whether the FC components between the disks and the HBA are also locked somehow.

Can't answer specifically, but generally installing larger drives into a RAID means they get treated as smaller drives, because all drives in the RAID group need to be the same size. Some arrays do clever stuff to rebalance, and will notice if you e.g. swap all of them and will let you extend the raid. Some RAID types to 'clever' things, with asymmetric ...
