PowerVault ME5: How to Shutdown or Restart a Controller

In this video we cover the process of shutting down or restarting a PowerVault Controller via the PowerVault Manager. Restarting controller processors can be required by a configuration change or to resolve an operational problem. Shutting down controller processors is recommended before either removing a controller module from its enclosure or powering off its enclosure for maintenance or a move. Caution: Shutting down or restarting a controller processor stops I/O to hosts and may cause service disruption. In a single-controller system, I/O to hosts will be unavailable until the controller is back online. In your dual-controller system, I/O to hosts continue on the partner controller if the mapping configuration and multipath are properly set. I/O to hosts is also unavailable if both controllers are shutdown/restarted simultaneously. A complete controller restart usually takes approximately 2-5 minutes.

Hi there. In this video, we'll walk through how to shut down or restart a controller via the PowerVault Manager. Before continuing, please note that shutting down or restarting a controller stops all communication to the hosts and may cause disruption.

To begin, log into the PowerVault Manager with your administrator credentials. Click on the Maintenance tab on the left and select Hardware from the dropdown. With the enclosure selected, click on the Actions dropdown and click on Restart/Shut Down System.

To shut down the controller, select "Shut Down SC Operation." And to restart the controller, select Restart SC Operation. Select the controller module to shut down or restart, A. B, or both. Select Apply and a confirmation panel will appear. Click OK to continue with the desired process. And that's it.

Thanks for everything. Watching.
