Number Severity Description/Recommended actions
• 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.
478 Info. A problem reported by event 476 or 477 is resolved.
Recommended actions:
• No action is required.
479 Error The controller reporting this event was unable to ush 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 ush or restore operation.
Recommended actions:
• If this is the rst 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.
480 Error An IP address conict 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 conict.
481 Error The periodic monitor of CompactFlash hardware detected an error. The controller was put in write-through
mode, which reduces I/O performance.
Recommended actions:
• Restart the Storage Controller that logged this event.
• If this event is logged again, shut down the Storage Controller and replace the CompactFlash.
• If this event is logged again, shut down the Storage Controller and replace the controller module.
482 Warning One of the PCIe buses is running with fewer lanes than it should.
This event is the result of a hardware problem that has caused the controller to use fewer lanes. The system
works with fewer lanes, but I/O performance is degraded.
Recommended actions:
• Replace the controller module that logged this event.
483 Error An invalid expansion-module connection was detected for the indicated disk channel. An egress port is
connected to an egress port, or an ingress port is connected to an incorrect egress port.
Recommended actions:
• Visually trace the cabling between enclosures and correct the cabling.
484 Warning No compatible spares are available to reconstruct this disk group if it experiences a disk failure. Only disk
groups that have dedicated or suitable global spares will start reconstruction automatically.
This situation puts data at increased risk because it will require user action to congure a disk as a dedicated or
global spare before reconstruction can begin on the indicated disk group if a disk in that disk group fails in the
future.
