Understanding the CAM Event Log

Refer to the Sun StorageTek Common Array Manager User Guide for your version of CAM for information on viewing system events and configuring automatic notifications.

In the event list below, note the following designations:

Down: Identifies a device or component as not functioning and in need of immediate service.
Critical: Identifies a device or component in which a significant error condition is detected that requires immediate service.
Major: Identifies a device or component in which a major error condition is detected and service may be required.
Minor: Identifies a device or component in which a minor error condition is detected or an event of significance is detected.

Note - Auto Service Request (ASR) monitors the array system health and performance and automatically notifies the Sun Technical Support Center when critical events occur. Critical alarms generate an Auto Service Request case. The notifications enable SunService to respond faster and more accurately to critical on-site issues.

Table 5-1 CAM Events for the Sun Storage J4500 Array

Code	Event Name	Severity	Description
xx.5.13	ValueChangeEvent-.disk	Major/Critical	The Disk has changed state from OK to something else. Action: A disk may have been removed, or failed. Check the alarm log for additional events.
xx.5.19	ValueChangeEvent-.fan	Major/Critical	A fan has changed state from OK to something else. Action: Check fan LEDs to locate the fault and replace the faulty fan to ensure nominal system operating temperature.
xx.5.227	ValueChangeEvent-.ps	Major/Critical	A power supply has changed state from OK to something else. Action: check the event log and chassis fault LEDs to find the trouble. Replace the faulty power supply.
xx.5.586	ValueChangeEvent-.chassis	Major/Critical	Chassis has had a negative state change. Action: Look for other events that can help identify the problem, check chassis fault LEDs. Replace any failed components.
xx.5.590	ValueChangeEvent-.overTemperatureFailure	Major	The system has detected a critical over-temperature. Action: This event should have shut down the array. Look for other events that can help identify the problem. Check the array's cooling vents and environment. You will need to press the array's power button to re-apply main power to the array, Check chassis fault LEDs and replace any failed components.
xx.5.591	ValueChangeEvent-.overTemperatureWarning	Major	The system has detected a warning temperature. Action: Look for other events that can help identify the problem. Check the array's cooling vents and environment. Check chassis fault LEDs and replace any failed components.
xx.11.21	CommunicationEstablishedEvent.ib	Minor	Indicates that communication has been re-gained to the storage array via the in-band path.
xx.12.21	CommunicationLostEvent.ib	Major/Critical	Indicates that communication has been lost to the array, and that the last path successfully used was the in-band communication path.
xx.12.31	CommunicationLostEvent.oob	Major/Critical	Indicates that communication has been lost to the proxy host connected to the storage array.
xx.14.16	DiscoveryEvent	Minor	Indicates that the discovery of an array or proxy host containing one or more arrays has occurred.
xx.41.13	ComponentRemoveEvent.disk	Major/Critical	A disk has changed state from OK to a removed state. Action: Check the alarm log to determine whether the disk has failed or has been removed for maintenance.
xx.41.19	ComponentRemoveEvent.fan	Minor	A fan has changed state from OK to a removed state. Action: Check the alarm log to determine whether the fan has failed or has been removed for maintenance.
xx.41.227	ComponentRemoveEvent.ps	Minor	A power supply has changed state from OK to a removed state. Action: Check the alarm log to determine whether the power supply has failed or has been removed for maintenance.
xx.75.42	RevisionDeltaEvent.revision	Minor	The firmware revision of the enclosure is not at baseline. Action: upgrade firmware to baseline.
