I have the exact same RAID card, you can not add drives to the RAID
without rebuilding the whole unit, which means you will loose the
content of the RAID array. I'm sure that's not what you want to do

If you add two drives, you can get into the card utility (you press
Ctrl-A I think at boot time) and you create a new array with the two
drives as a  RAID1. By default the two disks will appear a BOD (bunch
of disk)

They will appear as one disk in linux which you can add very easily in
the LVM (provided your existing RAID5 array is in a LVM

it won't help you to use the exact same drives
