Warning
A scrub-disk-group job encountered an error at the indicated logical block address.
The event message always includes the disk group name and the logical block address of the
error within that disk group. If the block with an error falls within the LBA range used by a
volume, the event message also includes the volume name and the LBA within that volume.
Recommended actions:
●
Examine event 207 that was logged previously to this event. Follow the recommended
actions for that event.

524
Error
A temperature or voltage sensor reached a critical threshold.
A sensor monitored a temperature or voltage in the critical range. When the problem is resolved,
event 47 is logged for the component that logged event 524.
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 recommended actions resolve the issue, replace the disk or controller
module that logged the error.
