Lock-down code
Description
LL
The controller cannot access either midplane SBB EEPROM.
Ln A module is not valid for a controller.
LP Drive port mapping tables are not detected.
Lr A component that is not a field replaceable unit (FRU) has been replaced.
Lt A configuration data base corruption has been detected.
LU
The SOD reboot limit has been exceeded.
In some cases, controllers detect errors during the startup process. The following table describes seven-
segment startup errors and conditions that result in the controller being in a suspended state:
Startup error code Description
S1 The controller detects a checksum failure in EEPROM.
S2 The SBB Signature/Revision is invalid.
S3
An unsupported enclosure is detected in the storage
array.
S4 The power supplies are incapable of powering the
controller.
S5 The SBB pairing has failed.
Critical Events Reference
Critical events from DE Series arrays display certain defined fields in the alert and SNMP trap messages.
Storage array alert traps
When a critical Major Event Log (MEL) event is generated, the embedded SNMP agent delivers a storage
array alert trap to all configured trap destinations. This message contains the following data:
MIB variable field Description
Storage array name Storage array user label. If the label contains non-ASCII
characters, the resulting variable binding is populated
with the fixed string "NonASCII Name." If the label is
blank, the variable binding is populated with the fixed
string "Unnamed."
Event type
Event Code (4-digit hexadecimal) for the particular MEL
event that prompted the trap.
Event time Timestamp of event in MM/DD/YYYY HH:MM:SS (24-
hour clock) format. Note this is always controller/GMT
time.
Event description Description of the specific MEL event that prompted the
trap.
Event component type
String representation of component type for the MEL vent
that prompted the trap. Defaults to "Not Available" if
component type cannot be identified.
Event component location
This data is not populated by the embedded SNMP agent
running on the controller at this time.
