Chapter 4 Verify That the Network Is Functional

Perform the steps described below to verify that the SCI network functions correctly.

Run get_ci_status

Execute get_ci_status on all cluster nodes to verify interconnectivity.

Run ifconfig -a

Execute ifconfig -a to verify that all the nodes are up with the SCI daemons running.

Ping the SCI Adapter Cards

Ping each SCI network interface, using their IP addresses. This verifies that every network interface can be reached from a single point in the network.

Do All-to-All Ping

Cause each node to ping the SCI interface on every other node. This verifies that any node can reach any other node over the SCI network.

Check for RSM Daemon

Check to see that the RSM daemon, hpc_rsmd, is running. This verifies that the RSM layer is functional.

Verify Basic Communication Functionality

Chapter 5 of the Sun HPC ClusterTools 3.0 Installation Guide describes procedures for verifying that the cluster can successfully perform a basic set of functions. These procedures include tests of internode communication. Execute the procedures provided in that chapter as a final verification of the SCI network.
