Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
28 Info. Controller parameters have been changed.
This event is logged when general configuration changes are made. For example, utility priority,
remote notification settings, user interface passwords, and network port IP values. This event is
not logged when changes are made to disk group or volume configuration.
Recommended actions:
● No action is required.
31 Info. The indicated disk is no longer designated as a spare.
Recommended actions:
● No action is required.
32 Info. Disk group verification has started.
Recommended actions:
● No action is required.
33 Info. Controller time/date has been changed.
This event is logged before the change happens, so the timestamp of the event shows the old
time. This event may occur often if NTP is enabled.
Recommended actions:
● No action is required.
34 Info. The controller configuration has been restored to factory defaults.
Recommended actions:
● No action is required.
37 Info. Disk group reconstruction has started. When complete, event 18 is logged.
Recommended actions:
● No action is required.
38 Info. A temperature, voltage, or current measurement changed from error or warning to OK.
Recommended actions:
● No action is required.
39 Warning The sensors monitored a temperature or voltage in the warning range. When the problem is
resolved, event 47 is logged for the component that logged event 39.
If the event refers to a disk sensor, disk behavior may be unpredictable in this temperature
range.
Check the event log to determine if more than one disk has reported this event.
● If multiple disks report this condition there could be a problem in the environment.
● If one disk reports this condition, there could be a problem in the environment or the disk has
failed.
Recommended actions:
● Check that the storage system’s fans are running.
● Check that the ambient temperature is not too warm. The controller enclosure operating
range is 5°C to 35°C (41°F to 95°F). The expansion enclosure operating range is 5°C to
40°C (41°F to 104°F).
● Check for any obstructions to the airflow.
● Check that there is a module or blank plate in every module slot in the enclosure.
● If none of these explanations apply, replace the disk or controller module that logged the
error.
40 Error The sensors monitored a temperature or voltage in the failure range. When the problem is
resolved, event 47 is logged for the component that logged event 40.
