Ok, thanks a lot for your info. Actually it was a hardware problem, not
a grub issue. Autoid was making a little mess. ;)

I could solve it now, system boots and disk is usable. Still one
question: is there a more intelligent way to manage all this? I decided
to go for a pure scsi system to add as many disks as i need (more or
less) but if whenever i add a hdd i must reconfigure all scsi id's to
preserve the device map it gets really tricky.

Thanks again!
