How do I perform a rollback on a target in an operation?

Purpose

You can trigger the rollback action on an execution in an operation, which will perform the rollback workflow defined for the operation on the target of that execution. After a rollback has been performed, the target of the rollback is marked as failed for the remainder of the operation, no further executions can be performed on the target, and previous executions cannot be retried.

Before you can perform the rollback action, a rollback workflow must be defined in the mapping file for the operation, and the rollback_allowed parameter must be true. When you perform a rollback on an execution in a completed phase, the phase enters the in-progress state, and other phases cannot start until the rollback is complete.

Some operations can be configured to automatically perform a rollback on failed targets, using the Rollback Type setting. Automatic rollback is only available for operations with the rollback_type parameter in the mapping file for the operation configured to automatic. Not all operations support automatic rollback. Contact a Nokia support representative for assistance with modifying an operation to use automatic rollback.
