Probably a stupid question, but is there a reason why you aren't you using the on-board SCSI controller? Also, what version of IRIX is installed? Or, more to the point, it needs at least 6.5.17...

Hello vishnu,

Thank you for your prompt reply. But the reason why I can't use the on-board SCSI is that I don't have the proper cable!  The connector on the Fuel mainboard is different from the ones used on most of the relevant SCSI add-on cards!  I don't really have a clue why the system was designed like that.
As for the version of the IRIX, I don't know. I haven't been successful to get the system "see" any data on both of the HDDs which I have. 
As OP says. the HDD is visible in the "hinv" output, but trying to do "ls" or "boot" results in a 'no such device' error.

Thanks and Best Regards,
AK
