That's since there are too many broken devices that erroneously
respond on LUNs > 0 even though they shouldn't.  This policy is
enforced in /sys/scsi/scsiconf.c with the following entry:

#if NSD > 0
	{
		T_DIRECT, T_DIRECT, T_FIXED, "*", "*", "*",
		"sd", SC_ONE_LU
	},
#endif /* NSD */

So now, go into this file, and add a record for your disk array saying
it actually can do more than one LUN correctly:

        {
                T_DIRECT, T_DIRECT, T_FIXED, "CMD TECH", "DAYTONA", "*",
                "sd", SC_MORE_LUS
        },

If it works, let us know.  (freebsd-scsi@freebsd.org is a better name
of a list for this, or even better, use send-pr.)
