SP System. Each dependent node has a node_number and other configuration and status
information which is unique to that dependent node.
Procedure
1 Check the SP Switch cable for obvious problems such as a loose or disconnected
connector. If any problems are found, correct the problem.
2 Check the 10Base-T twisted-pair connection between the SP Switch Router control board
and the SP control workstation. This connection is normally routed through an Ethernet
hub.
3 If there is no terminal directly-attached to the SP Switch Router, check the SP Switch
Router host name from the SP control workstation. From the control workstation, enter:
SDRGetObjects DependentNode node_number reliable_hostname
This will return the node numbers and the corresponding host names for the SP Switch
Router systems.
4 Test Ethernet connectivity by performing a ping test from the SP control workstation to
the SP Switch Router administrative Ethernet address.
5 Check the status of the SP Switch Router Adapter LEDs.
Use the tables in the “SP Switch Router Adapter LEDs” section in Chapter 1 to determine
the state of the card.
Generally, “RX ST0/ST1/ERR” and “TX ST0/ST1/ERR” will indicate a problem. The
problem might be due to connection, configuration, hardware, or software.
To further test the SP Switch Router Adapter card hardware, you can reset or reseat the
card, and then use the tables under “LED activity during boot” (Chapter 1) to interpret the
results.
Note: Before you reset an SP Switch Router Adapter card or re-seat a card in the router
chassis, be sure that the switch node has been fenced. Use an Efence command to take the
dependent node off the switch node.
6 From the SP control workstation, use an Eunfence and/or Estart command to bring the
dependent node back into the configuration.
From the control workstation, check switch_responds for a good value.
If switch_responds returns "1" or shows green in Perspectives, then the dependent
node is active again.
7 You may need to log in to the SP Switch Router to perform additional analysis before
determining whether any hardware needs replacement.
8 If problems remain, you will have to contact the next level of Customer Support for further
direction. They may log into the SP Switch Router to perform additional analysis. If you
were directed here by the RS/6000 SP Maintenance Information Manual Dependent Node
MAP, return to that procedure.
For more information about configuration as related to the SP, see the PSSP Administration
Guide and the PSSP Command and Technical Reference. For additional information on
troubleshooting your configuration, see the PSSP Diagnosis Guide.
