Setting SCSI Device IDs
4. Set the SCSI ID on the disk drives; ID 7 is reserved for the controller. 
Note
Each drive must have a unique ID chosen from 
0 through 6 or 8 through 15. Be careful not to 
duplicate a drive address. 
Remember: ID 7 is reserved for the controller; 
therefore, it cannot be used as a disk drive ID.
ID’s from 0 through 6 are usually for Narrow, 
8-bit devices. However, the full range of SCSI ID 
addresses, 0 through 6 and 8 through 15 can be 
used for Wide, 16-bit devices. 
See your device documentation for instructions on 
how to set your particular disk drive’s SCSI address.
