What kind of controller, and what kind of disks?  When its missing some
disks, is it reassigning the SCSI IDs accordingly to the disks that it
does see, or does it remember that the 'missing' ones exist, and keep the
ID assignments the same?  Are you seeing errors, or just that sda is not
being detected?  Do you need all the disks to boot up?
