12.11 Things to Know – Lock-Down Codes for the Controller-Drive
Tray
Use the following table to determine the diagnostic lock-down code definitions on the seven-
segment display in the controller canister. In general, these diagnostics display only when the
controller is in a non-operational state. The controller can be in a non-operation state as a
result of a configuration problem (such as mismatched controller types) or as a result of a
hardware fault. If the amber controller service action required LED is on, the non-operational
state is the result of a hardware fault.
Supported diagnostic lock-down codes on the seven-segment display
Diagnostic Code Description
– – The firmware is booting.
L0 The controller types are mismatched, which result in a suspended
controller state.
L2 A persistent memory error has occurred, which results in a
suspended controller state.
L3 A persistent hardware error has occurred, which results in a
suspended controller state.
L4 A persistent data protection error has occurred, which results in a
suspended controller state.
