Why does my primary and most important drive show up with ghost images?
This is a SCSI issue. Check cables, termination, jumpers etc. Make sure that the SCSI cable is terminated at both ends and only at the ends. Check the documentation of the drive if there is a jumper which makes it answer on all LUN requests.
Also make sure that there are not two drives with the same ID.
All 1-7 scsi id's are filled/listed.
Are you sure that it's on all IDs and not rather on all LUNs of one ID ?
