•
For SFF disks, verify that the Power/Activity LED (left LED on front of disk) is illuminated green or
blinking green.
Remove the enclosure bezel to view disk LEDs. Attach the bezel when finished viewing disk LEDs.
Verify rear panel LEDs:
•
Verify that each power supply module’s Input Source Power Good LED (top LED on PSU) is illuminated
green.
•
Verify that the FRU OK LED on each IOM face plate is illuminated green, indicating that the module
has completed initializing, and is online.
Using management interfaces
In addition to viewing LEDs as described above, you can use management interfaces to monitor the health
status of the system and its components, provided you have configured and provisioned the system, and
enabled event notification (see “Getting Started” within the
AssuredSAN 4004 Series Storage
Management Guide
for more information).
Select from the following methods to verify component operation:
•
Use the SMC (v3) or RAIDar (v2) to 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 SMC and RAIDar
use 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 Health Recommendations field to resolve
the problem.
•
As an alternative to using the SMC or RAIDar, you can run the
show system
command in the CLI 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, 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 in the log, you can do so using the SMC,
RAIDar, or the CLI. Using either the SMC or RAIDar, you would view the event log and then hover over
the event message to see detail about that event. Using the CLI, you would run the
show events
detail
command (with additional parameters to filter the output) to see the detail for an event (see
“Alphabetical list of commands > show events” within the
AssuredSAN 4004 Series CLI Reference
Guide
for more information about command syntax and parameters).
