Repair a Controller
To repair a controller, first see 6.2.2 Viewing Event Details on page 111. The event details tell you the event ID and give
you a description of the event that caused the controller to need repair. Using this information, take measures to fix the
problem:
•
Typically, controller problems can be traced to a problem with the BBU, a logical drive, an array, a physical drive,
or an enclosure. In the navigation area, expand the problem controller’s tree and view its components in the
Contents area. Select a component that is in a critical state, and view the repair action.
•
Check all generated events; there may be more than one problem.
•
Replace parts as needed.
Remember that some events are the result of other events; one event can cause a cascade of others if left unfixed. For
example, a problem with a hard drive causes a warning event, “Hard drive error found”, which could lead to a
consistency check error event, “Consistency check on logical drive error”, which could lead to a serious event, “A hard
disk has failed”, which could lead to a critical event, “A logical drive has failed.”

Repair a BBU
Events that may cause a BBU to need repair:
•
Power supply failure
•
BBU power low
•
BBU recondition needed
•
BBU has failed
To repair a BBU, first see 6.2.2 Viewing Event Details on page 111. The event details tell you the event ID and give you
a description of the event that caused the BBU to need repair. Using this information, take measures to fix the problem:
•
If the BBU needs to be reconditioned or power is low, recondition the BBU. Remember that the battery must be
fully reconditioned before being used. If a BBU recondition has been canceled in the past, the BBU may not have
enough power to sustain the write-back cache.
•
Check, all cable connections, to be sure none is disconnected or broken.
•
Replace the BBU as needed.
