Describing the fields in the error event log

The error event log includes fields with information that you can use to diagnose problems.

Table 1 describes the fields that you see when you use the command-line interface to produce an error event log.

Table 1. Description of data fields for the error event log
Data field Description
Node identifier The name of the node that the error or event occurred on. If the event applies to a specific node, for example, it indicates that the fibre-channel port of the node is not working, then the node identifier is indicated here. If the event applies to the cluster rather than to a node, for example, a license limit is exceeded, then this field is set to 0.
Object type The object type to which the error event log relates. See Table 2.
Object ID A number that uniquely identifies the instance of the object.
Sequence number A number that identifies the event. Where appropriate, sense data is returned to host systems references the sequence number.
Root sequence number The sequence number of another log entry that enables all errors that have a single source to be marked as fixed by a single action.
First error timestamp The time when this error event was reported. If events of a similar type are being coalesced together, so one error event log record represents more than one event, this is the time the first error event was logged.
Last error timestamp The time when the last instance of this error event was recorded in the log.
Error count The number of error events coalesced into this error event log record.
Error ID This number is a unique identifier for the error or event.
Error code This number is used as the starting point for service procedures.
Status flag For details on the status flag, see Table 3.
Type flag For details on the type flag, see Table 5.
Additional sense data Data specific to this error or event code. This is a binary data record. When the error event log is viewed using the command line tools, this data is shown in hex. When the data is viewed using the Web interface, this data is translated to ASCII characters on the right side of the page. You are not normally required to interpret this data as part of the service procedures. However, any procedures that do refer to the data describe the ASCII format.

Table 2 describes the types of error-event log objects.

fc_adapter Fibre-channel adapter
Emailuser E-mail user
Syslog Syslog server
Snmp SNMP server
Smtp E-mail server
Auth_Group User group
SAS_Adapter SAS adapter
Table 3 shows the types of error-event log flags.
Note: Informational events only have the SNMP trap-raised flag on when configured to do so.
Table 3. Description of flags for the error-event log
Flag Description
Unfixed This log entry requires a service action.
Fixed This entry is marked as fixed. It remains in the error event log until it becomes the oldest record in the log, at which point it is overwritten by the next log entry.
Expired Some events require a certain number of occurrences in 25 hours before they are shown as unfixed. If they do not reach this threshold in 25 hours, they are flagged as expired. Any further events of this type are then placed in a new event log entry.
Table 4 shows the various combinations of flags that might be logged and the resulting status that is reported by the user interfaces. The Analyze Error Log panel in the SAN Volume Controller Console summarizes the status flags in the error event log record. The following table lists the status values shown, and the status flag combination that value represents.
Table 4. Reported status for combinations of error-log status flags
Reported Status UNFIXED ERROR_FIXED ERROR EXPIRED
BELOW_THRESHOLD 0 0 0
EXPIRED 0 0 1
UNFIXED 1 0 0
FIXED x1 1 0
Note: 1 This flag has no effect on the status.

Table 5 shows the error-event types.

Table 5. Description error-event types
Type Description
Error Cat 1 These errors require a service action. A Cat 1 error normally indicates a problem with a hardware component. A FRU or list of FRUs are included with the trap data sent with the error record.
Error Cat 2 These errors require a service action. A Cat 2 error normally indicates a configuration or environment problem rather than a hardware problem.
Transient error Errors of type transient have been recovered by an error recovery procedure.
Configuration event This entry is from the configuration event log. This flag is useful when displaying both logs in a seamless display as an aid to relating logged error conditions to configuration events.
Informational This type indicates that the log entry is an informational event. Information events can be used to warn the user about an unexpected configuration result or prompt a user to initiate further configuration actions.
