Fault isolation methodology
ME5 Series Storage Systems provide many ways to isolate faults. This section presents the basic methodology that is used to
locate faults within a storage system, and to identify the pertinent CRUs affected.
Use the PowerVault Manager to configure and provision the system upon completing the hardware installation. Configure
and enable event notification to be notified when a problem occurs that is at or above the configured severity. See the Dell
PowerVault ME5 Series Storage System Administrator's Guide for more information.
When you receive an event notification, follow the recommended actions in the notification message to resolve the problem. In
addition, see the following topics for troubleshooting guidance:

Cabling systems to replicate volumes is another important fault isolation consideration related to initial system installation. See
the ME5 Series Storage Systems Deployment Guide for more information about troubleshooting during initial setup.
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.
