onStackFailure

Determines what action will be taken if stack creation fails. If this parameter is specified, the DisableRollback parameter to the ExecuteChangeSet API operation must not be specified. This must be one of these values:

• DELETE - Deletes the change set if the stack creation fails. This is only valid when the ChangeSetType parameter is set to CREATE. If the deletion of the stack fails, the status of the stack is DELETE_FAILED.

• DO_NOTHING - if the stack creation fails, do nothing. This is equivalent to specifying true for the DisableRollback parameter to the ExecuteChangeSet API operation.

• ROLLBACK - if the stack creation fails, roll back the stack. This is equivalent to specifying false for the DisableRollback parameter to the ExecuteChangeSet API operation.

For nested stacks, when the OnStackFailure parameter is set to DELETE for the change set for the parent stack, any failure in a child stack will cause the parent stack creation to fail and all stacks to be deleted.
