Verifying component failure

Select from the following methods to verify component failure:
● Use the PowerVault Managerto check the health icons/values of the system and its components to either ensure that
everything is okay, or to drill down to a problem component. The PowerVault Manager uses health icons to show OK,
Degraded, Fault, or Unknown status for the system and its components. If you discover a problem component, follow the
actions in its Recommendation field to resolve the problem.
● As an alternative to using the PowerVault Manager, you can run the CLI show system command to view the health of the
system and its components. If any component has a problem, the system health will be Degraded, Fault, or Unknown. If
you discover a problem component, follow the actions in its Health Recommendations field to resolve the problem.
● Monitor event notification — With event notification configured and enabled, use the PowerVault Manager to view the
event log, or run the CLI show events detail command to see details for events.
● Check Fault LED (back of enclosure on controller module or IOM face plate): Amber = Fault condition.
● Check that the OK LED (back of enclosure) is off.
