Recovering IBM Power® Virtualization Center data
Use the powervc-opsmgr restore command to recover PowerVC data that was previously backed up so you can restore to a working state after data corruption or a disaster.
Before you begin
- The backup archive can only be restored to a system that is running the same level of PowerVC as the system from which the backup was
taken.Note: The restore can be done to a system with a different hardware architecture than the backup.
- The new environment should duplicate the original user environment, such as adding users and groups that are assigned roles in PowerVC. Otherwise, PowerVC users will not be available after the restore.
About this task
The backup process does not back up SSL certificates and associated configuration information. A restored PowerVC environment uses the configuration that existed within the PowerVC environment before the restore operation, not the configuration of the environment from which the backup was taken. Keep in mind this consideration when you are selecting an environment on which to restore.
By default, the
restore command does not restore monitoring. In order to
restore monitoring, you have the following options:
- Use the --monitoring flag in the restore command.
- Use the powervc-opsmgr monitoring --restore command that only restores the monitoring data.
For details about the syntax and options, run powervc-opsmgr restore
--help

Procedure
Results
Notes:
When the restore operation completes, PowerVC runs with all data from the targeted
backup file.- If an error occurs while running powervc-opsmgr restore, check the restore logs in /opt/ibm/powervc/log.
- In case of any failure in the restore logs, re-run the restore operation.
- If restore fails due to network disconnection or any other reason, you can re-run powervc-opsmgr restore -c <CLUSTER_NAME> to resume the restore operation.
- When restoring in a multinode environment, make sure you perform restore on the primary node.
