Chapter 11. Troubleshooting AEN Messages AEN (asynchronous event notifications) are messages issued by the 3ware RAID controller when an error is detected such or when an action is completed. These are summarized in Table 10. Descriptions of each are provided at the end of the table. If you use 3DM 2, AEN messages are displayed on the Alarms page. If you use the CLI, AEN messages can be listed using the show alarms command. On the 3DM 2 Alarms page, the AEN number is the last few digits within the parentheses at the beginning of the message description. For example, in the string (0x04:0x002B), "2B" is the AEN number. To find additional information about the AEN 2B, you would look up 02Bh on the pages below.
