Options available for performing basic steps

When performing fault isolation and troubleshooting steps, select the option or options that best suit your site environment.

Use of any option is not mutually exclusive to the use of another option. You can use the PowerVault Manager to check the health icons/values for the system, or to examine a problem component. If you discover a problem, either the PowerVault Manager or the CLI provides recommended-action text online. Options for performing basic steps are listed according to frequency of use:

  • Use the PowerVault Manager
  • Use the CLI
  • Monitor event notification
  • View the enclosure LEDs

Use the PowerVault Manager

The PowerVault Manager uses health icons to show OK, Degraded, Fault, or Unknown status for the system and its components. The PowerVault Manager enables you to monitor the health of the system and its components. If any component has a problem, the system health is in a Degraded, Fault, or Unknown state. Use the PowerVault Manager to find each component that has a problem. Follow actions in the Recommendation field for the component to resolve the problem.

Use the CLI

As an alternative to using the PowerVault Manager, you can run the show system CLI command to view the health of the system and its components. If any component has a problem, the system health is in a Degraded, Fault, or Unknown state, and those components are listed as Unhealthy Components. Follow the recommended actions in the component Health Recommendation field to resolve the problem.

Monitor event notification

With event notification configured and enabled, you can view event logs to monitor the health of the system and its components. If a message tells you to check whether an event has been logged, or to view information about an event, use the PowerVault Manager or the CLI. Using the PowerVault Manager, view the event log and then click the event message to see detail about that event. Using the CLI, run the show events detail command to see the detail for an event.

View the enclosure LEDs

You can view the LEDs on the hardware to identify component status. If a problem prevents access to the PowerVault Manager or the CLI, viewing the enclosure LEDs is the only option available. However, monitoring/management is often done at a management console using storage management interfaces, rather than relying on line-of-sight to LEDs of racked hardware components.
