This section details how to perform error recovery on the controller.
To display a list of all current controller system and drive enclosure faults, enter: faults
4.2.1 Component Failure Recovery
The controller contains redundant and hot-swappable fans and power supply units. A single component
failure, therefore, will not shut down the system. However, in the unlikely event of component failure,
you can replace the failed component while the controller is running. The replaced component will
automatically be returned to service once the component has been installed and booted up.
4.2.1.1 Power Supply Failure
A power supply failure message will be displayed on your console if a power supply fails. The status
LED on the power supply module will turn off (Figure 4–4).
Figure 4–4 Power Modules - Front View
NOTE :
Make sure you have the replacement power supply available before removing the failed
module.
1. Remove the cover panel (if the panel is installed).
2. Locate the failed power supply module (indicated by an off Status LED).
3. Turn off module’s power switch (found on back of unit).
