Thanks for the reply. That was my first suggestion to the editor, but he doesn’t want to have to do anything more than select the A&B cam and group by source tc. For now I’ll just have to mount them initially on on a pc and then move the drive.
Success! HAd 3 new fibre channel connections installed and the cables were the wrong way round. reversed the 2 parts of the fibre cable and now its working like a charm.
