Compaq HSZ80 manual Setting Scsi Target ID Numbers, Host Scsi Bus

Setting SCSI Target ID Numbers

In a subsystem, every SCSI device is assigned its own SCSI ID number. Setting an ID number, though, really depends on which SCSI bus you are talking about—the host SCSI bus or the controller device bus, which are both shown in Figure 2–7.

Host SCSI Bus

Each BA370 rack-mountable enclosure in a configuration supports a range of SCSI target ID numbers. Each controller can access the target ID numbers that you specify with either of the following commands:

SET THIS_CONTROLLER PORT_1_ID = (n,n)

or

SET THIS_CONTROLLER PORT_2_ID = (n,n)
