Request and Display System Routing

How to use the rtr command to view system routing.

Use the HSS rtr command to request routing for the HSN, to verify current route configuration, or to display route information between nodes. Upon startup, rtr determines whether it is making a routing request or an information request.

For more information, see the rtr(8) man page.

Display routing information

The --system-map option to rtr writes the current routing information to stdout or to a specified file. This command can also be helpful for translating node IDs (NIDs) to physical ID names.

Route the entire system

The rtr -R | --route-system command sends a request to perform system routing. If no components are specified, the entire configuration is routed as a single routing domain based on the configuration information provided by the state manager. If a component list (idlist) is provided, routing is limited to the listed components. The state manager configuration further limits the routing domain to omit disabled blades, nodes, and links and empty blade slots.
