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
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 detect-
ing some sort of read error. The default operation of the
is to abort a rebuild if an error is encountered. If it is
age switch
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 com-
pletion 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 "roll-
call" of all drives attached to the card. After detection of the drives,
the storage switch then uses an internal algorithm to logically con-
nect 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.
