3ware Escalade Storage Switch User Guide AEN 002h AEN_DEGRADED_UNIT An error has been encountered and the array is operating in degraded (non-redundant) mode.The user should replace the bad drive as soon as possible and initiate a rebuild. AEN 003h AEN_CONTROLLER_ERROR The storage switch has encountered an internal error. Please contact 3ware customer support. AEN 004h AEN_REBUILD_FAIL The storage switch was unable to complete a rebuild operation. This error can be caused by drive errors on either the source or the destination of the rebuild. However, due to ATA drives ability to reallocate sectors on write errors, the rebuild failure is most likely caused by the source drive of the rebuild detecting some sort of read error. The default operation of the storage switch is to abort a rebuild if an error is encountered. If it is desired to continue on error, the Ignore errors on rebuild radio button can be checked prior to initiating a rebuild. AEN 005h AEN_REBUILD_DONE The storage switch has successfully completed a rebuild. The completion of the rebuild changes the state of the array from rebuilding to OK. The data is now redundant. AEN 006h AEN_INCOMP_UNIT At power on initialization time, the storage switch performs a "rollcall" of all drives attached to the card. After detection of the drives, the storage switch then uses an internal algorithm to logically connect drives that belong to the same array. If after rollcall a member of an array is not found, the INCOMPLETE UNIT AEN is sent. Examples of incomplete units are as follows: • 4 drive RAID 5 with 1 drive missing. • 2 drive RAID 1 with 1 drive missing. 150 www.3ware.com
