28 Restoring an appliance from a backup file

This chapter describes how to use the UI, REST APIs, or a custom-written PowerShell script to restore a corrupted appliance from a backup file. A restore operation is required only to recover from catastrophic failures, not to fix minor problems that can be resolved in other ways.

IMPORTANT: Do not use any hypervisor-provided capabilities or snapshots to restore an HP OneView appliance because doing so can cause synchronization errors and result in unpredictable and unwanted behavior.

28.1 Roles

Users with Infrastructure administrator or Backup administrator privileges can create and download backup files, however, only an Infrastructure administrator can restore an appliance from a backup file.

28.2 Restore operation overview

You can restore an appliance from a backup file that was created on the same appliance or, if an appliance fails and cannot be repaired, from a backup file from a different appliance.

During a restore operation, the appliance firmware reconciles the data in the backup file with the current state of the managed environment. There are some discrepancies that a restore operation cannot resolve automatically. After a restore operation is complete, the Infrastructure administrator must manually resolve any remaining inconsistencies, which are identified by activities.

See also “Post-restoration tasks” (page 224).

IMPORTANT: After the restore operation, you need to upload the firmware baselines required by your server profiles, enclosures, and logical interconnects. Refer to each profile's Firmware baseline setting to determine the file name for the required baseline. You do not need to upload the default baseline, HP Service Pack for ProLiant - Base Firmware, which is included in the appliance image.

You should only use a restore operation to recover from catastrophic failures. Do not use it for minor problems that can be resolved in other ways.

Restoring a backup file replaces all management data and most configuration settings on the appliance.

The appliance is not operational during a restore operation.It can take several hours to perform a restore operation.A restore operation cannot be canceled or undone after it has started.
