Number Severity Description/Recommended actions
468 Info. FPGA temperature has returned to the normal operating range and the speed of buses
connecting the FPGA to downstream adapters has been restored. The speed was reduced to
compensate for an FPGA over-temperature condition.
This event indicates that a problem reported by event 469 is resolved.
Recommended actions:
● No action is required.
469 Warning The speed of buses connecting the FPGA to downstream adapters has been reduced to
compensate for an FPGA over-temperature condition.
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 these recommended actions resolve the issue, replace the controller module that
logged the error.
When the problem is resolved, event 468 is logged.
470 Warning Removal of the indicated disk groups 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 groups completed successfully.
Recommended actions:
● No action is required.
471 Error A replication was queued because the secondary volume is detached.
Recommended actions:
● To allow the replication to proceed, reattach the secondary volume and then resume the
replication.
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.
475 Info. Replication was queued because the secondary volume is in an offline state.
