Understanding the CAM Event Log

This section provides event IDs, log listings, descriptions, and where applicable, Service action recommendations.

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:


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

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.
