Introduction

Prerequisites

Requirements

Cisco recommends that you have knowledge of the Nexus CLI.

Components Used

The information in this document is based on Cisco Nexus 5010/5020 switches only. It does not
affect Cisco Nexus 5548/5596 switches.

The information in this document was created from the devices in a specific lab environment. All of
the devices used in this document started with a cleared (default) configuration. If your network is
live, make sure that you understand the potential impact of any command.

Problem

Multiple interfaces on Card 2 are down, and you see this alert:

N5020 %$ VDC-1 %$ %NOHMS-2-NOHMS_DIAG_ERROR: Module 1: Runtime diag detected major event

The alert suggests a card failure, but some ports are up. Even though the Nexus 5020 switch is
online, the Fiber Channel (FC) module in Slot 2 is offline. Enter the show module command in
order to view the status of the modules:
