Performing light path analysis

Complete this task to use the LED indicators on your storage unit to determine if there is a resource event that can be repaired without using the DS Storage Manager.

Use the LED indicators located on the front display panel and rear display panel as well as the individual resources within your server or expansion enclosure to determine if an event has occurred. Light path indicators provide indications of both fault and informational events.
  1. Move to the front of your server enclosure.
  2. Look at the front display panel to determine if any of the indicators are lit.
  3. If the amber information indicator is lit, view the logs page of the DS Storage Manager to determine any further actions.
  4. If the amber system alert light is lit, perform one of the following actions, depending on the other indicators that are lit:
    • If the fault on opposite side indicator is lit, move to the rear of the enclosure.
    • If the fault in external enclosure indicator is lit, move to the attached expansion enclosure that has the system alert indicator lit and repeat this step and the successive steps for that expansion enclosure.
    • If neither fault on opposite side nor the fault in external enclosure indicators are lit, stay at the front of the server enclosure. The fault is located on one of the disk drive modules.
  5. Find the resource on the side of the enclosure that contain a fault that have a solid fault/service indicator. This is the resource that needs to be replaced.
  6. Follow the removal and replacement procedures to replace the resource. After replacing the resource, the process automatically begins to bring the resource online. If, after the resource is fully online, the system alert indicators are still lit, repeat these steps to find the next resource that requires service.
