Unfortunately it is SCSI 3 (Ultra320) which, in itself, is "chainable"
however I believe that there may be a limitation based on the SCSI ID
of the individual drives. I will have to do some experimentation to
see if this is possible.

Thanks for your suggestion. It is not one I had thought of as I am
so used to limiting one array to one controller.

Regards, Hugh
