You actually have to use array controller commands to access them. The cpqfc driver quietly translated these internally, so it's th= e only driver that will work with the RA4100 array (unless someone writes an ULD for type array controller). Unfortunately, compaq discontinued support for cpqfc a while ago and the driver has been decaying in the tree (to the point where it won't really build now).
