ok so if you are using a hardware raid on a E450 i think you are using a SRC/P scsi raid controller.. unlike Sun's other hardware raid products, there is only 1 command that comes with SRC/P, /opt/SUNWhwrdg/dptutil, use this command to check the status of the logical storage units, or build new "LSU's".
Hope it helps,
