Problems
To aid serviceability, the appliance detects persistent hardware failures ( faults ) and software
failures ( defects , often included under faults) and reports them as active problems on this
screen. If the phone home service is enabled, active problems are automatically reported to
Oracle Support, where a support case may be opened depending on the service contract and the
nature of the fault.
Active problems display
For each problem, the appliance reports what happened, when the problem was detected, the
severity and type of the problem, and whether it has been phoned home. Below are some
example faults as they would be displayed in the BUI:
