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 (four options are described below) is not mutually exclusive to the use of another option. You can use the ME Storage Manager to
check the health icons/values for the system and its components to ensure that everything is okay, or to drill down to a problem
component. If you discover a problem, either the ME Storage Manager or the CLI provide recommended-action text online. Options for
performing basic steps are listed according to frequency of use:

Use the ME Storage Manager
The ME Storage Manager uses health icons to show OK, Degraded, Fault, or Unknown status for the system and its components. The ME
Storage Manager enables you to monitor the health of the system and its components. If any component has a problem, the system health
will be Degraded, Fault, or Unknown. Use the web application’s GUI to drill down to find each component that has a problem, and follow
actions in the Recommendation field for the component to resolve the problem.
Use the CLI
As an alternative to using the ME Storage 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 will be Degraded, Fault, or Unknown, and those components will be
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 directs you to check whether an event has been logged, or to view information about an event in the log, you can do so using the
ME Storage Manager or the CLI. Using the ME Storage Manager, you can 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 (with additional parameters to filter the output) to see
the detail for an event.
View the enclosure LEDs
You can view the LEDs on the hardware (while referring to LED descriptions for your enclosure model) to identify component status. If a
problem prevents access to the ME Storage Manager or the CLI, this is the only option available. However, monitoring and management
are often done at a management console using storage management interfaces, rather than relying on line-of-sight to LEDs of racked
hardware components.
Performing basic steps
You can use any of the available options described in performing the basic steps comprising the fault isolation methodology.
Gather fault information
When a fault occurs, it is important to gather as much information as possible. Doing so will help you determine the correct action needed
to remedy the fault.
