HP OneView manual Restore an appliance from a backup file

28.4 Restore an appliance from a backup file

Before you restore an appliance from a backup file, note the following:

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

•The appliance is not operational during a restore operation.

•A restore operation cannot be canceled or undone after it has started.

•Use the latest backup file to restore the appliance. Changes made after the backup file is created cannot be saved.

•Restoring an appliance from a backup file replaces all management data and most configuration settings on the appliance. You are directed to re-enter unresolved data, if applicable.

•The appliance firmware referenced in the backup file must be identical to the firmware running on the appliance; otherwise, the restore operation fails.

•The appliance blocks login requests while a restore operation is in progress.

•It can take several hours to perform a restore operation; the more resources and devices to restore, the longer the process takes.

•Restoring the appliance validates the resource inventory (enclosures, servers, interconnects, and so on).

•During the restore operation, HP OneView refreshes each enclosure to validate its contents—especially to ensure that the appliance still claims them. Then, HP OneView refreshes each blade server and clears the virtual IDs of any servers added to an enclosure since the last time the backup file was created. HP OneView also refreshes all rack servers to ensure the appliance still claims them.

The appliance will also clear virtual IDs for servers that do not have a profile assigned but do have virtual IDs configured. These servers most likely had a profile assigned after the last backup was made.

•If you removed, and then re-added an enclosure after a backup file was created, and then perform a restore operation using that backup file, you must refresh the enclosure before the appliance can connect.

•If you added server hardware to the appliance after the backup file was created, that hardware is not in the appliance database when the restore operation completes. You must add that hardware to the appliance and then repeat any other configuration changes (such as assigning server profiles) that were made between the time the backup file was created and the restore operation completed.

HP recommends that you perform frequent backups, and especially after adding any hardware or changing the configuration.

After restoring the appliance, you must upload all the firmware bundles that were used by your existing server profiles, enclosures, and logical interconnects. Refer to each profile’s Firmware baseline setting, which displays the file name of the required baseline.

You do not need to upload the default firmware bundle, HP Service Pack for ProLiant - Base Firmware. It is already included in the appliance image.

Prerequisites
