ONTAP 9.xのADPモードな2ノードスイッチレスクラスタで、node-2のディスクをnode-1に割り付け、筐体全体で一つのデータ用アグリゲートを作る準備をしてみます。
※手順を誤ると、次回起動時にcoreループに陥りますので、壊れても良い状態で作業を行って下さい
※壊してしまった場合の筐体初期化については別ポストにて
作業手順
- node-1およびnode-2を初期化し、再起動、Cluster Setup画面で^Cを押下、adminでログインしておきます
- node-2で次の手順でパーティションの割り付け状況を確認します。

※相方ノードのスペアパーティションが対象になります - node-2をhaltでシステム停止します
※電源は切らないで下さい - node-1でhalt → boot_ontap → ^C にてメンテナンスモードに遷移し、先程調べたパーティションを付け替えます

- haltし、再起動します
*> halt LOADER-A> boot_ontap
※Cluster Setupに遷移しますが、一旦放置下さい - node-2を boot_ontap で再起動し、Cluster Setupのプロンプト画面にします
※プロンプト画面で一旦放置下さい - node-1 から初期設定作業を開始して下さい
- node-2 の設定も完了させ、クラスタ状態にして下さい
- データ用アグリゲートを作成下さい
以上です。
