Hello Simon
I used smit, not commands
disks appear in listings (and that's what led me to wrong conclusions...)
I didn't run diags because it's a machine i can hardly stop
some more investigations and tries showed endly a problem with the scsi cable
I replaced it with a brand new one and now everything is working fine
I think this kind of problem happens when only a wire of the wide part
(data bits 8-15) is defective, because it's not used in basic scsi
protocol, only for data transfer (well, it's my opinion). It would of
course have been much easier to diagnostic if it had been another wire...
thanks a lot

Bien sûr que je suis perfectionniste !
Mais ne pourrais-je pas l'être mieux ?
