2–34Configuring an HSZ80 Array Controller

You can view IDs on this controller with the following command:

SHOW THIS_CONTROLLER FULL

You can view IDs on the other controller with the following command:

SHOW OTHER_CONTROLLER FULL

The valid target ID numbers are 0–15, with one ID reserved for each host controller on the host bus. When both ports are in use, the 16 target ID numbers are shared across ports. Once a target ID has been set on one port, that same target may not be used on the other port.

Using more than one target ID number allows the controller to present more units to the host. Enclose multiple ID numbers in parentheses and separate each by a comma: (n1, n2, n3, . . .)

Device SCSI Bus

Device addressing allows the controller to identify the location of devices based on a port-target-LUN (PTL) number described in “Device PTL Addressing Convention within the Controller,” page 3–36.
