Enclosure LED Status Indicators
If you use an enclosure that
has an integrated AMCC/3ware CCU (chassis
control unit),
the LEDs on your enclosure also provide some status
information. The chassis should come with a cable which attaches to the I
2
C
port on the controller.
Unit Statuses
The following is a list of unit statuses you may see in 3DM:
•
OK.
The unit is optimal and is functioning normally.
•
Rebuilding.
The unit is in the process of writing data to a newly added
disk in a redundant unit, in order to restore the unit to an optimal state.
Note:
The following table is an example only. Check with your chassis
documentation for more details. Not all features may be supported or implemented
in the same way.
