Can anyone out there help on a point of interest ? I seem to recall that
someone on this network mentioned the fact that with SCSI-2 you could
achieve 256 LUN devices on one SCSI address by using the extended message
format. I have looked through my copy of the SCSI-2 specification and have
found no reference to extended messages and LUNs. How is this achieved ?
And is it just an 'adaptation' of SCSI ?
