A storage administrator has just been informed by their network team that a WAN outage...

To verify that the VPLEX Metro WAN COM link is restored, the storage administrator should run the connectivity validate-local-com command. This command checks the connectivity status of the local communication links within the VPLEX cluster.

Command Execution: The administrator should access the VPLEX CLI and execute the connectivity validate-local-com command. This will initiate a check of the local COM ports’ connectivity status1.

Interpreting Results: After running the command, the administrator should review the output to verify that all expected connectivity is present. The output will indicate whether each local COM port is communicating as expected1.

WAN COM Link: The WAN COM link is responsible for the communication between VPLEX clusters over a wide area network. Ensuring that the local COM links are operational is a prerequisite for the WAN COM link to function properly1.

Post-Outage Verification: Following a WAN outage, it’s crucial to confirm that the communication links are fully operational to maintain the high availability and data mobility features of VPLEX Metro1.

Best Practices: It is recommended to follow the Dell EMC VPLEX best practices for post-outage recovery, which include running the connectivity validate-local-com command to ensure that the system is ready to resume normal operations1.

In summary, the connectivity validate-local-com command is the correct procedure to verify that the VPLEX Metro WAN COM link is restored, as it checks and confirms the presence of all expected local communication link connectivity within the VPLEX cluster.
