Viewing the Event Log

Use the Event Log to see a list of events that occur in the storage array. The event log is stored on reserved areas on the physical disks in the storage array. The event log records configuration events and the failure of storage array components.

You can set the event log to show only critical events. All critical events are sent to the SNMP management console or to the email recipient that you have configured to receive alert notifications.

The Event Log shows summary information for each event in the list.
Information Description
Date/Time The date and time that the event occurred. The date and time are set from the RAID controller module clocks.
Priority - Critical or Informational A critical event shows a problem with the storage array. If you correct the problem immediately, you might prevent losing access to the data.

An informational event shows information about the storage array. This information does not show a critical problem with the storage array.

Component Type The type of component that is affected by the event. The component type might indicate a physical component, such as a physical disk, or a logical component, such as a virtual disk.
Component Location The location of the component that is affected by the event. The location shows the enclosure or slot for the component.
Description A short description of the event.

You can view details for each event. The event details shows additional information about the event. A Technical Support representative might request this information.
