SCSI Address (Target ID) Selection
Each drive or device on a specific SCSI channel must be configured for a
target address (or target ID) that is different from all other devices on that
channel. The target ID, a SCSI address number from 0 to 15, is assigned to
each device attached to a SCSI channel during installation.
The default SCSI address for the DAC960PG controller is target ID 7.
Subsequently, you must assign to each connected disk drive a different
(unique) SCSI address, typically a target ID number from 0 through 15 (with
the exception 7, which is reserved on each channel for the controller).
