Hi uunix,
I gave your suggestions above a try and still get the same result. It seems that if I add just one drive (either an internal drive or external on the FC tray) it always saves. But as soon as you add a second or subsequent drive, it barfs and gives the same error message about the drive being used twice in the data disk list for partition zero.
I do have the sw_license file in place and I assume if that wasn't you would get the "unlicensed" message in each disk icon.

I also dug out an old SUN SCSI disk array that had 6x300Gb drives in it and connected that up to the external SCSI port and gave it a go. But as above, the first drive you can save ok but second onward also result in the same message.
this has got me totally stumped as the previous configuration using the SGI TP4600 unit as 5x 1Gb WD drives in it and it it saved without any complaints!
My next step is my brother is bringing one of his Octane2 2008 flame systems to connect the trays to and see if we can persuade sw_config to save a config off on those. Fingers crossed!
Cheers
