  • Managing faults
    Patent number: 7757123
    Abstract: Faults are managed. A problem is detected in a data storage system. Possible field replaceable units (FRUs) of the data storage system are identified that may be at fault for the problem. If only one FRU may be at fault, a definitive alert is issued identifying the FRU. If multiple FRUs may be at fault, fault isolation is executed. If fault isolation isolates the problem to only one FRU, a definitive alert is issued naming the FRU. If fault isolation does not isolate the problem to only one FRU, an ambiguous alert is issued identifying multiple FRUs. The user is directed to execute a troubleshooting tree, which execution includes a manual FRU replacement by the user.
