Error Messages

This appendix describes the error messages produced by the various components of the NAS software. It includes the following sections:

About Error Messages

This appendix describes the specific error messages sent through email, Simple Network Management Protocol (SNMP) notification, the liquid crystal display (LCD) panel, and the system log to notify the administrator in the event of a system error. SysMon, the monitoring thread in the NAS software, monitors the status of redundant array of independent disks (RAID) devices, uninterruptible power supplies (UPSs), file systems, NAS servers, controller units, expansion units, and environmental variables. Monitoring and error messages vary depending on model and configuration.

About SysMon Error Notification

SysMon, the monitoring thread in NAS appliances and gateway systems, captures events generated as a result of system errors. It then takes the appropriate action of sending an email, notifying the Simple Network Management Protocol (SNMP) server, displaying the error on the liquid crystal display (LCD) panel, writing an error message to the system log, or some combination of these actions. Email notification and the system log include the time of the event.

Reference: UPS Errors

Refer to TABLE B-1 for descriptions of uninterruptible power supply (UPS) error conditions.

TABLE B-1 UPS Error Messages
Event	Email Subject: Text	SNMP Trap	LCD Panel	Log
Power Failure	AC Power Failure: AC power failure. System is running on UPS battery. Severity = Error Action: Restore system power.	EnvUpsOn Battery	U20 on battery	UPS: AC power failure. System is running on UPS battery.
Power Restored	AC power restored: AC power restored. System is running on AC power. Severity = Notice	EnvUpsOff Battery	U21 power restored	UPS: AC power restored.
Low Battery	UPS battery low: UPS battery is low. The system will shut down if AC power is not restored soon. Severity = Critical Action: Restore AC power as soon as possible.	EnvUpsLow Battery	U22 low battery	UPS: Low battery condition.
Normal Battery	UPS battery recharged: The UPS battery has been recharged. Severity = Notice	EnvUps Normal Battery	U22 battery normal	UPS: Battery recharged to normal condition.
Replace Battery	Replace UPS Battery: The UPS battery is faulty. Severity = Notice Action: Replace the battery.	EnvUps Replace Battery	U23 battery fault	UPS: Battery requires replacement.
UPS Alarms - Ambient temperature or humidity outside acceptable thresholds	UPS abnormal temperature/humidity: Abnormal temperature/humidity detected in the system. Severity = Error Action: Check UPS unit installation. Contact Sun Services.	EnvUps Abnormal	U24 abnormal ambient	UPS: Abnormal temperature and/or humidity detected.
Write-back cache is disabled.	Controller Cache Disabled: Either AC power or UPS is not charged completely. Severity = Warning Action: If AC power has failed, restore system power. If after a long time the UPS is not charged completely, check the UPS unit and replace if necessary.		Cache Disabled	write-back cache for ctrl x disabled
Write-back cache is enabled.	Controller Cache Enabled: System AC power and UPS are reliable again. Write-back cache is enabled. Severity = Notice		Cache Enabled	write-back cache for ctrl n enabled
UPS is shutting down.	UPS shutdown: The system is being shut down because there is no AC power and the UPS battery is depleted. Severity = Critical			!UPS: Shutting down
UPS Failure	UPS failure: Communication with the UPS unit has failed. Severity = Critical Action: Check the serial cable connecting the UPS unit to the NAS server, or Check the UPS unit and replace if necessary.	EnvUpsFail	U25 UPS failure	UPS: Communication failure.

Reference: File-System Errors

TABLE B-2 describes file-system error messages that occur when the file-system usage exceeds a defined usage threshold. The default usage threshold is 95 percent.

TABLE B-2 File-System Errors
Event	Email Subject: Text	SNMP Trap	LCD Panel	Log
File System Full	File system full: File system <name> is xx% full. Severity=Error) Action: Delete any unused or temporary files, or Extend the partition by using an unused partition, or Add additional disk drives and extend the partition after creating a new partition.	PartitionFull	F40 FileSystemName full	File system <name> usage capacity is xx%.

Reference: RAID Errors

TABLE B-3 displays events and error messages for the redundant array of independent disks (RAID) subsystem.

TABLE B-3 RAID Error Messages
Event	Email Subject: Text	SNMP Trap	LCD Panel	Log
LUN Failure	RAID LUN failure: RAID LUN N failed and was taken offline. Slot n is offline. Action: Replace bad drives and restore data from backup. Severity = Error	RaidLunFail	R10 Lun failure	RAID LUN N failed and was taken offline. Slot n is offline. (Severity=Error)
Disk Failure	Disk drive failure: Disk drive failure. Failed drives are: Slot no., Vendor, Product ID, Size Severity = Error	RaidDiskFail	R11 Drive failure	Disk drive failure. Failed drives are: Slot#, Vendor, Product ID, Size (Severity=Error)
Controller Failure	RAID controller failure: RAID controller N has failed. Action: Contact Sun Services. Severity = Error	RaidControllerFail	R12 Ctlr failure	RAID controller N failed.

Reference: IPMI Events

The NAS software uses the Intelligent Platform Management Interface (IPMI) board to monitor environmental systems, and to send messages regarding power supply and temperature anomalies. Device locations are shown in Appendix D.

TABLE B-4 describes the IPMI error messages for the NAS software.

TABLE B-4 IPMI Error Messages
Event	Email Subject: Text	SNMP Trap	LCD Panel	Log
Fan Error	Fan Failure: Blower fan xx has failed. Fan speed = xx RPM. Action: The fan must be replaced as soon as possible. If the temperature begins to rise, the situation could become critical. Severity = Error	envFanFail trap	P11 Fan xx failed	Blower fan xx has failed!
Power Supply Module Failure	Power supply failure: The power supply unit xx has failed. Action: The power supply unit must be replaced as soon as possible. Severity = Error	envPowerFail trap	P12 Power xx failed	Power supply unit xx has failed.
Power Supply Module Temperature	Power supply temperature critical: The power supply unit xx is overheating. Action: Replace the power supply to avoid any permanent damage. Severity = Critical	envPowerTemp Critical trap	P22 Power xx overheated	Power supply unit xx is overheating.
Temperature Error	Temperature critical: Temperature in the system is critical. It is xxx Degrees Celsius. Action: 1. Check for any fan failures, OR 2. Check for blockage of the ventilation, OR 3. Move the system to a cooler place. Severity = Error	envTemperatue Error trap	P51 Temp error	The temperature is critical.
Primary Power Cord Failure	Power cord failure: The primary power cord has failed or been disconnected. Action: 1. Check the power cord connections at both ends, OR 2. Replace the power cord. Severity = Error	envPrimary PowerFail trap	P31 Fail PWR cord 1	The primary power cord has failed.
