5.4 Testing DSSI Storage Devices
5.4.1 Entering the DUP Driver Utility from Console Mode
To examine and change DSSI parameters, you must first activate the DUP
driver utility by setting host to the specific device for which you want to modify
or examine parameters.
Use the following command for embedded DSSI:
SET HOST/DUP/DSSI/BUS:<bus_number> <node_number> PARAMS
where:
<bus_number> is the DSSI bus number (0 or 1), and <node_number> is the
bus node ID (0–6) for the device on the bus.
In Example 5–19, the command shown at the prompt is entered to start the
DUP server for the ISE at node 0 of embedded DSSI bus 1.
Example 5–19 Accessing the DUP Driver Utility from Console Mode
(Embedded DSSI)
>>>SET HOST/DUP/DSSI/BUS:1 0 PARAMS

5.5 Using MOP Ethernet Functions to Isolate Failures
The console requester can receive LOOPED_DATA messages from the server
by sending out a LOOP_DATA message using NCP to set this up. An example
follows.
Identify the Ethernet adapter address for the system under test (system 1) and
attempt to boot over the network.
***system 1 (system under test)***
>>>SHOW ETHERNET
