フェイルオーバー構成エラーが原因で、クラスタからのノードの削除が失敗します

クラスタから2つのノードを削除しようとすると、次のエラーが表示されます。

ONTAP 9.3以前：

Cluster::*> cluster unjoin -node Node-03

ONTAP 9.4以降：

Cluster::*> cluster remove-node -node Node-03

Warning: This command will remove node "Node-03" from the cluster.
     You must remove the failover partner as well. After the node is
     successfully removed, erase its configuration and initialize all disks
     by using the "Clean configuration and initialize all disks (4)" option
     from the boot menu.
Do you want to continue? {y|n}: y
[Job 67508] Job is queued: Cluster remove-node of Node:Node-03 with UUID:e0-cf5a-11e5-81c4-97e6917e55c2.

Error: command failed: [Job 67508] Job failed:

Removing a node only works for nodes not in failover configuration.
Node Node-03 is SFO enabled with partner node Node-04.
