After a motherboard replacement on a NetApp AFF A300 in a SAN environment, the customer...

Here is my reasoning:

The system node hardware unified-connect show command displays the status and configuration of the Unified Connect ports on a node1. This command can help you identify if the ports are configured correctly and if they have any errors or faults.

The ports 0e and 0f on the AFF A300 are 10GbE ports that support both Ethernet and Fibre Channel over Ethernet (FCoE) protocols2. These ports are part of the Unified Connect feature, which enables you to use the same physical port for different protocols without requiring additional hardware3.

If the ports are offline, it could indicate a problem with the port configuration, the cable connection, the switch configuration, or the protocol settings. The system node hardware unified-connect show command can help you troubleshoot these issues by showing you the port mode, speed, duplex, state, and error count1.

The other commands in the options are not as helpful for troubleshooting the port issue, because they show different information that is not related to the Unified Connect feature or the port status. For example:

The vserver fcp wwpn-alias show command displays the World Wide Port Name (WWPN) aliases for the Fibre Channel Protocol (FCP) logical interfaces (LIFs) on a Vserver4. This command can help you manage the FCP LIFs, but it does not show the status of the physical ports or the Unified Connect feature.

The storage port show command displays the status and configuration of the storage ports on a node5. This command can help you manage the storage ports, but it does not show the status of the Unified Connect ports or the FCoE protocol.

The vserver fcp interface show command displays the status and configuration of the FCP LIFs on a Vserver6. This command can help you manage the FCP LIFs, but it does not show the status of the physical ports or the Unified Connect feature.
