Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
● No action is required.
498 Info. A disk copyback operation completed.
Recommended actions:
● No action is required.
Warning A disk copyback operation failed.
When a disk fails, reconstruction is performed using a spare disk. When the failed disk is
replaced, the data that was reconstructed in the spare disk (and any new data that was written
to it) is copied to the disk in the slot where the data was originally located. This is known as slot
affinity.
However, this copyback operation failed. This may be because the disk that was inserted as
a replacement for the failed disk is also faulty or because the source disk for the copyback is
faulty. This failure may also be caused by a fault in the midplane of the enclosure that the disks
are inserted into.
Recommended actions:
● Look for another event logged at approximately the same time that indicates a disk failure,
such as event 8, 55, 58, or 412. Follow the recommended actions for that event. If the
problem then recurs for the same slot, replace the chassis FRU.
499 Info. A disk copyback operation started. The indicated disk is the destination disk.
When a disk fails, reconstruction is performed using a spare disk. When the failed disk is
replaced, the data that was reconstructed in the spare disk (and any new data that was written
to it) is copied to the disk in the slot where the data was originally located. This is known as slot
affinity.
For the copyback operation, the reconstructed disk is called the source disk, and the newly
replaced disk is called the destination disk. All of the data is copied from the source disk to the
destination disk and the source disk then becomes a spare disk again.
Recommended actions:
● No action is required.
500 Info. A disk copyback operation completed. The indicated disk was restored to being a spare.
When a disk fails, reconstruction is performed using a spare disk. When the failed disk is
replaced, the data that was reconstructed in the spare disk (and any new data that was written
to it) is copied to the disk in the slot where the data was originally located. This is known as slot
affinity.
For the copyback operation, the reconstructed disk is called the source disk, and the newly
replaced disk is called the destination disk. All of the data is copied from the source disk to the
destination disk and the source disk then becomes a spare disk again.
Recommended actions:
● No action is required.
501 Error The enclosure hardware is not compatible with the I/O module firmware.
The Expander Controller firmware detected an incompatibility with the midplane type. As a
preventive measure, disk access was disabled in the enclosure.
Recommended actions:
● If using a supported enclosure, update the storage system to the latest firmware. If using an
unsupported enclosure, replace the unsupported enclosure with a supported one.
502 Warning The indicated SSD has 5% or less of its life remaining.
This event will be logged again as the device approaches and reaches its end of life.
Recommended actions:
● Be sure you have a spare SSD of the same type and capacity available.
