Fabric verification confirms that the Cornelis Omni-Path installation is complete and correct before the cluster is placed into production. The procedures in this chapter should be performed after hardware installation, software installation, and initial Fabric Manager startup are complete, and after all fabric ports have reached the Active state.

During fabric validation, unexpected loads on Host CPUs may result in inconsistent performance results. As a debug step, isolate the issue using the Omni-Path tool to verify CPU host load. By default, it captures the top ten most heavily loaded hosts.

# /usr/sbin/opacheckload -f /etc/opa/allhosts

After the high load hosts have been identified, the next step is to root cause the issues.

For any issues encountered during verification that are not discussed herein, refer to the CN5000 Maintenance and Troubleshooting Guide.
