Problems

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 Sun 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:

Date
Description
Type
Phoned Home
2009-09-16 13:56:36
SMART health-monitoring firmware reported that a disk failure is imminent.
Major Fault
Never
2009-09-05 17:42:55
A disk of a different type (cache, log, or data) was inserted into a slot. The newly inserted device must be of the same type.
Minor Fault
Never
2009-08-21 16:40:37
The ZFS pool has experienced currently unrecoverable I/O failures.
Major Error
Never
2009-07-16 22:03:22
A memory module is experiencing excessive correctable errors affecting large numbers of pages.
Major Fault
Never

This information can also be viewed in the CLI:

Problems:

COMPONENT    DIAGNOSED            TYPE            DESCRIPTION
problem-000  2010-7-27 00:02:49   Major Fault     SMART health-monitoring
                                                  firmware reported that a
                                                  failure is imminent on disk
                                                  'HDD 17'.

Selecting any fault shows more information about the fault including the impact to the system, affected components, the system's automated response (if any), and the recommended action for the administrator (if any). In the CLI, only the "uuid", "diagnosed", "severity", "type", and "status" fields are considered stable. Other property values may change from release to release.

For hardware faults, you may be able to select the affected hardware component to locate it on the Hardware screen.

Repairing problems

Problems can be repaired by performing the steps described in the suggested action section. This typically involves replacing the physical component (for hardware faults) or reconfiguring and restarting the affected service (for software defects). Repaired problems no longer appear on this screen.

While the system typically detects repairs automatically, in some cases manual intervention may be required. If a problem persists after the affected components have been repaired, contact support. You may be instructed to mark the problem repaired. This should only be done under the direction of service personnel or as part of a documented Sun repair procedure.
