Number Severity Description/Recommended actions
As a preventative measure, the local Expander Controller (EC) is holding the partner Expander
Controller (EC) in a reset loop.
Recommended actions:
● Remove the partner controller module from the enclosure. Boot the partner controller
module in single-controller mode in a separate enclosure (without the controller module that
reported this event). Load the latest compatible bundle version. If the version fails to load,
replace the partner controller module.
531 Error The indicated controller module was unable to recover from a stall. The system will need to be
manually recovered.
Recommended actions:
● Download the debug logs from your storage system and contact technical support. A service
technician can use the debug logs to determine the problem.
Warning The indicated controller module detected a stall. The system will perform corrective actions.
Recommended actions:
● No action is required.
532 Warning The partner controller module was killed due to encountering a protection information error
during a write operation to disk.
If retries are successful after failover, the controller is deemed at fault. Otherwise, the disk is
the likely cause of failure.
Recommended actions:
● Replace the killed controller if retry is successful after failover. Otherwise (if disk errors are
encountered), replace the disk and bring the controller back into operation.
533 Error This event provides details about the result of the MC test of the indicated component.
If the test succeeded, the message says the component is present and operational. If the test
failed, the message says the component is unavailable.
Recommended actions:
● If the event indicates the test failed, replace the controller module that logged this event.
Info. This event provides details about the result of the MC test of the indicated component.
Recommended actions:
