Seven-segment display lock-down codes
Diagnostic lock-down codes are displayed when the controller is not operational, either because of a
configuration problem or a hardware fault. The lock-down code is displayed as part of the seven-segment
display sequence.
The following table includes the lock-down codes and describes the conditions that cause the controller to
be in a suspended state:
Lock-down code
Description
L0
The controller types in a two-controller configuration are mismatched.
L1
Missing interconnect canister.
L2
A persistent memory error has occurred.
L3
A persistent hardware error has occurred.
L4
A persistent data protection error has occurred.
L5
An auto-code synchronization (ACS) failure has been detected.
L6
An unsupported HIC has been detected.
L7
A sub-model identifier either has not been set or has been mismatched.
L8
A memory configuration error has occurred.
L9
A link speed mismatch condition has been detected in either the I/O module (IOM) or
the power supply.
Lb
A HIC configuration error has been detected.
LC
A persistent cache backup configuration error has been detected.
Ld
A mixed cache memory DIMMs condition has been detected.
LE
Uncertified cache memory DIMM sizes have been detected.
LF
