Component Status

The component status in the Hardware page is color coded as follows:

  • Green - denotes a 'Healthy' component
  • Yellow - pertains to a component in 'Warning' state
  • Red - relates to components that have 'FAILED' or 'DEGRADED'
  • White with black text - is the case when a component is not present

The snippets shown below depict this color-coding scheme.

Auto-Refresh

The Auto-refresh option available on this page is disabled by default. It is however enabled when an upgrade is in progress. But if the user chooses to navigate away from the 'Hardware' page while an upgrade is in progress, the button will then be disabled. This button ensures that the status of the components is continuously updated when an upgrade has commenced.

Restart and Shutdown an Appliance Controller

A single node of the appliance can now be gracefully shut down using the 'Shutdown Active Controller' button.

In situations where you need to restart the active controller such as a software upgrade, click the ‘Restart Active Controller’ button. You will be prompted to confirm the action through a browser pop-up. Confirming this action will take you to a progress page as shown below.

RestartingActiveController_S.png

 

Restarting an appliance is not disruptive to connected initiators, assuming the standby controller is available. TCP connections between initiators and the active controller will be reset, but will be re-established once the standby controller assumes operation. There may be a temporary (less than 30 second) pause in I/O activity between initiators and the appliance during the course of this operation.

ShuttingDownActiveController_S.png

 

If you need to shut down a controller, remove it from the chassis as per the Hardware Replacement Guide. In order to return the controller to service, you must insert it into the chassis as per the Hardware Replacement Guide.

 

 Note: Restarting a controller or shutting down an appliance should not be required as part of normal system operation. Shutdown operations are common generally only in cases where failed hardware requires replacement, the unit is being physically moved, or when taking an appliance out of service. Note that a running controller should never be physically removed as this would result in a loss of redundancy and an increased risk of data loss.

 Note: For appliance models 5020 and 7020, connections from iSCSI initiators may not automatically re-establish upon failover if the server using the volume does not have any outstanding IOs waiting for that particular volume. This is expected behavior, and the connection will be re-established when the application using volumes mounted via iSCSI needs to perform IOs against those volumes.

View Appliance

The 'View Appliance' button present on the hardware page when clicked will show the rear and front view images of the appliance and EBOD enclosure. These images can be used to understand the location of various components such as MGMT and DATA ports. As long as the management is working, this image can be viewed and hence even used as a guide for cabling.

Different images show up based on the model type. A sample image is shown below:

Appliance or a component not healthy

In case you encounter a component that is not 'healthy', please contact StorSimple Support. If the call-home is enabled on your appliance, you will receive an email alert. If the 'Notification Settings' are configured, an optional email is also sent automatically to StorSimple Support.
