Understanding the system error log
The PowerHA® SystemMirror® software logs messages to the system error log whenever a daemon generates a state message.
The PowerHA SystemMirror messages in the system error log follow the same format used by other AIX® subsystems. You can view the messages in the system error log in short or long format.
In short format, also called summary format, each message in the system error log occupies a single line. The description of the fields in the short format of the system error log:
| Field | Description |
|---|---|
| Error_ID | A unique error identifier. |
| Time stamp | The day and time on which the event occurred. |
| T | Error type: permanent (P), unresolved (U), or temporary (T). |
| CL | Error class: hardware (H), software (S), or informational (O). |
| Resource_name | A text string that identifies the AIX resource or subsystem that generated the message. PowerHA SystemMirror messages are identified by the name of their daemon. |
| Error_description | A text string that briefly describes the error. |
In long format, a page of formatted information is displayed for each error.
Unlike the PowerHA SystemMirror log files, the system error log is not a text file.
The AIX errpt command generates an error report from entries in the system error log. For information on using this command see the errpt man page.
