Description/Recommended actions
Recommended actions:
• No action is required.
Replication was queued because the secondary volume is in an offline state.
Recommended actions:
• To allow the replication to proceed, resolve the problem that is preventing access to the secondary
volume.
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 these recommended actions resolve the issue, replace the controller module that logged the
error.
When the problem is resolved, event 478 is logged.
The CPU temperature exceeded the normal range so the CPU speed was reduced. 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 these recommended actions resolve the issue, replace the controller module that logged the
error.
When the problem is resolved, event 478 is logged.
A problem reported by event 476 or 477 is resolved.
Recommended actions:
• No action is required.
The controller reporting this event was unable to flush data to or restore data from non-volatile memory.
This mostly likely indicates a CompactFlash failure, but it could be caused by some other problem with the
controller module. The Storage Controller that logged this event will be killed by its partner controller, which
will use its own copy of the data to perform the flush or restore operation.
Recommended actions:
• If this is the first time this event has been logged, restart the killed Storage Controller.
• If this event is then logged again, replace the CompactFlash.
• If this event is then logged again, shut down the Storage Controller and replace the controller module.
An IP address conflict was detected for the indicated iSCSI port of the storage system. The indicated IP
address is already in use.
Recommended actions:
• Contact your data-network administrator to help resolve the IP address conflict.
The periodic monitor of CompactFlash hardware detected an error. The controller was put in write-through
mode, which reduces I/O performance.
