Replacement of HCA IB network port cards in SuperCluster requires additional steps to ensure the new component has the correct firmware installed and to reconfigure the HCA port GUID's in the Infiniband Fabric. Failure to do so leaves the system in a dysfunctional state and causes further downtime for the customer. This document describes how to replace a faulty Infiniband card in SuperCluster Compute and Database Nodes and ensure that the FW is updated and the port GUID's are correct.
