A volume normally refers to a "disk" created via a "volume manager" such as Veritas or a volume created by an operating system such as Windows NT.
 A LUN refers to a "logical unit number" presented to a host as a SCSI ID. (i.e., LUN number 1 specifies SCSI ID 1 on that port. Therefore, the term volume can be considered software based and LUN considered hardware based.
