Warning
Removal of the indicated disk group(s) completed with failure.
Removal of disk groups can fail for several reasons, and the specific reason for this failure is included with the
event. Removal most often fails because there is no longer room in the remaining pool space to move data
pages off of the disks in the disk group.
Recommended actions:
•
Resolve the issue specified by the error messaging included with this event and re-issue the request to
remove the disk group.
Info.
Removal of the indicated disk group(s) completed successfully.
Recommended actions:
•
No action is required.
473
Info.
The indicated volume is using more than its threshold percentage of its virtual pool.
This is an indication that the storage usage crossed the user-specified threshold for this volume. If the storage
usage drops below the threshold, event 474 is logged.
Recommended actions:
•
No action is required. How this information is utilized is left to the discretion of the user.
474
Info.
The indicated volume is no longer using more than its threshold percentage of its virtual pool.
This event indicates that the condition reported by event 473 is no longer applicable.
Recommended actions:
•
No action is required.
476
Warning
The CPU temperature exceeded the safe range so the CPU entered its self-protection state. IOPS were
reduced.
The storage system is operational but I/O performance is reduced.
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 the above explanations apply, replace the controller module that logged the error.
When the problem is resolved, event 478 is logged.
477
Info.

•
Check that the ambient temperature is not too warm. The controller enclosure operating range is 5°C to
