MAP 0550: Dependent Node
MAP 0550: Dependent Node
A dependent node is a general term which refers to a switch adapter installed externally to the 9076 SP,
but connected to the SP switch. In the current implementation, a dependent node refers to each RS/6000
SP Switch Router Adapter installed in the RS/6000 SP Switch Router (machine type 9077). There may be
several SP Switch Router Adapters (dependent nodes) in each SP Switch Router, but each occurrence is
called a dependent node.
This MAP resolves problems specific to switch communication between the SP Switch Router Adapter and
the SP switch. For any other problem with the SP Switch Router, refer to the "SP Switch Router Adapter
Guide" or other documentation supplied with the SP Switch Router.
Note: If there are multiple SP Switch Router Adapters in the system, you can find out configuration infor-
mation and identify them by using the following commands:
SDRGetObjects DependentNode (returns more information)
SDRGetObjects DependentAdapter (returns IP address and netmask)
By referring to the dependent node_number, you can identify the location of the SP Switch Router
Adapter as follows:
"reliable_hostname" indicates hostname of the SP Switch Router
"extension_node_identifier" indicates two-digit slot number of the SP Switch Router Adapter in
the SP Switch Router.
001
Problem detected with switch communication to a dependent node.
– Check for an obvious problem with the switch cable between the switch assembly and the SP Switch
Router Adapter card, such as a loose or broken cable.
– Fix any obvious problem.
Was there an obvious problem?
Yes No
002
No obvious problems exist.
– Make sure the system administrator has performed problem determination procedures in the
RS/6000 SP: Diagnosis and Messages Guide and/or checked the configuration of the SP Switch
Router Adapter.
Was the customer able to fix a configuration problem?
Yes No
003
Continue service with the SP Switch Router (or SP Switch Router Adapter).
– If you are responsible for the SP Switch Router, check connectivity to the SP using
SP
Switch Router Adapter Guide.
Was there a problem found and corrected with the SP Switch Router or SP Switch
Router Adapter?
Yes No
