DESCRIPTION

CAUTION

Do not run the drive_group ‑restoreDriveGroup command unless explicitly instructed to do so by Oracle Customer Support. If you are recovering a drive group in which more than one drive has faulted, restoring the drive group with data loss could result in compromised data integrity.

If any of the data volumes a drive group were provisioned using a redundancy scheme other than RAID6, and two or more drives in the drive group are marked with a label that indicates failure, the Oracle FS System takes the drive group offline. Offline drive groups are marked DEGRADED_CRITICAL. To recover the data on the faulted drives, first run the drive_group ‑forceOnline command. If, after running the command, only one drive is reported as CRITICAL, WARNING, or MISSING, replace the drive. If two or more drives are marked with a label that indicates failure, contact Oracle Customer Support.

To recover the data on the faulted drives, Oracle Customer Support might request that you first run the drive group ‑restoreDriveGroup drive‑group‑id‑or‑fqn command before instructing you to replace the drives. If the recovery command succeeds, the Oracle FS System restores the affected data volumes with minimal data loss. If the command fails, Oracle Customer Support might request that you review the system alerts by running the system_alert ‑list ‑details command and reporting the results. The Oracle Customer Support representative may also provide you with a procedure for collecting system logs.

Only administrators with primary administrator or admin1 roles are authorized to run this command.

OPTIONS

‑driveGroup: Specifies the fully qualified name (FQN) or the unique identifier (ID) of the drive group. When a Drive Enclosure is added to the Oracle FS System, the system automatically allocates the storage by generating one or more drive groups. The drive_group ‑list command displays the names of all drive groups that are defined on the Oracle FS System. The FQN consists of the name that the system generates preceded by a forward slash (/) character.
‑withDataLoss: Indicates that the data volumes on the specified drive group will be restored with data loss after the compromised drives are replaced. If not specified, the SAN LUNs or file system tiers can come online with minimum data loss after drive replacement.
