Description/Recommended actions
◦ If the disk then has a status of leftover (LEFTOVR), clear the metadata to reuse the disk.
◦ If the associated disk group is offline or quarantined, contact technical support.
• If reconstruction of a disk group failed:
– If the associated disk group is online, clear the indicated disk's metadata so that the disk can be re-
used.
– If the associated disk group is offline, the CLI trust command may be able to recover some or all of
the data in the disk group. However, trusting a partially reconstructed disk may lead to data corruption.
See the CLI help for the trust command. Contact technical support for help to determine if the trust
operation applies to your situation and for help to perform it.
• 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.
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:
• No action is required.
The indicated disk has been designated a global spare.
Recommended actions:
• No action is required.
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:
• 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.
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:
• No action is required.
A rescan has completed.
Recommended actions:
• No action is required.
