What Caused the Problem?
Communications with the minihub canister has been lost. This may be the result of a minihub canister failure, a controller failure, or a failure in an internal backplane communications board. If there is only one minihub failure, the storage subsystem is still operational. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
Caution
Electrostatic discharge can damage sensitive components. Use a grounding wrist strap or other anti-static precautions before removing or handling components.
