Number Severity Description/Recommended actions
•
•
9 Info. The indicated spare disk has been used in the indicated disk group to bring it back to a fault-tolerant status.
Disk group reconstruction starts automatically. This event indicates that a problem reported by event 8 is
resolved.
Recommended actions:
•
16 Info. The indicated disk has been designated a global spare.
Recommended actions:
•
18 Error Disk group reconstruction completed with errors.
When a disk fails, reconstruction is performed using a spare disk. However, this operation failed. Some of the
data in the other disk(s) in the disk group is unreadable (uncorrectable media error), so part of the data
cannot be reconstructed.
Recommended actions:
•
•
Info. Disk group reconstruction completed.
For the ADAPT disk group that completed partially, either there is no available spare space, or the spare
space cannot be used because of ADAPT fault-tolerant requirements.
Recommended actions:
•
19 Info. A rescan has completed.
Recommended actions:
•
20 Info. Storage Controller firmware update has completed.
Recommended actions:
•
21 Error Disk group verification completed. Errors were found but not corrected.
Recommended actions:
•
Warning Disk group verification did not complete because of an internally detected condition such as a failed disk. If a
disk fails, data may be at risk.
Recommended actions:
If the associated disk group is offline and you do not want to use the trust command, perform these
steps:
• Delete the disk group (CLI remove disk-groups command).
• Clear the indicated disk's metadata so the disk can be re-used (CLI clear disk-metadata
command).
• Replace the failed disk or disks. (Look for other instances of event 8 in the event log to determine
which disks failed).
• Re-create the disk group (CLI add disk-group command).
If an SSD that was part of a disk group has reported that it has no life remaining, replace the disk with one
of the same type and the same or greater capacity. For continued optimum I/O performance, the
replacement disk should have performance that is the same as or better than the one it is replacing.

If you do not have a backup copy of the data, take a backup.
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.
