HP MSA Events Description Reference Guide (762785-001, March 2014)

Event descriptions 63
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 enclosure operating range is 5–40 C
(41 F–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 the above explanations apply, replace the disk or controller module that logged the error.
527
Error Expander Controller (EC) firmware is incompatible with the enclosure.
As a preventative measure, the Expander Controller (EC) disabled all PHYs and reported the short
enclosure status page in the supported diagnostic list.
Recommended actions
• Upgrade the controller module to the latest supported bundle version.
528
Error Expander Controller firmware detected that the partner Expander Controller (EC) firmware is incompatible
with the enclosure.
As a preventative measure, the Expander Controller (EC) disabled all PHYs and reported the short
enclosure status page in the supported diagnostic list.
Recommended actions
• Upgrade the partner controller module to the latest supported bundle version.
529
Error The local Expander Controller (EC) is incompatible with the enclosure.
As a preventative measure, the Expander Controller (EC) disabled all PHYs and reported the short
enclosure status page in the supported diagnostic list.
Recommended actions
• Replace the controller module with one that is compatible with the enclosure.
