Mirroring Novell 6.6 Servers

I am settting up two identical Novell 6.6 servers to replace two Novell 4.2 servers that are already mirrored usinf an MSL card. Is it possible to mirror the new servers with an MSL card or do i must use clustering and how? I’ve got two 36GB hdd in each. If one server fails i would like the other to take over.
