環境

  • ONTAP 9
  • ストレージのテイクオーバー/ギブバック

概要

手順

System Manager
  • System Manager を使用してノードの再起動を実行する
  • ノードが再起動すると、HA パートナーは自動的にテイクオーバーを実行します
  • 再起動が完了したら、System Manager からギブバックオプションを実行できます
ONTAP CLI
  1. 両方のノードが storage failover show コマンドで接続されていることを確認します:

cluster1::>storage failover show
 Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 true Connected to cluster1-02
cluster1-02 cluster1-01 true Connected to cluster1-01
2 entries were displayed.

  1. Possibleフィールドが false の場合、 ストレージフェイルオーバーを有効にしてから 続行してください。
  2. テイクオーバー対象のノードのテイクオーバーを開始します:

cluster1::>storage failover takeover -ofnode <nodename>

次の例では、cluster1-02という名前のノードがテイクオーバーされます

cluster1::>storage failover takeover -ofnode cluster1-02
Warning: A takeover will be initiated. Once the partner node reboots, a giveback will be automatically initiated. Do you want to continue? {y|n}: y

  1. テイクオーバーの進捗状況を確認します:

cluster1::>storage failover show
 Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01    cluster1-02   true     Takeover scheduled. cluster1-02
                    has relocated its SFO aggregates in
                    preparation of takeover.
cluster1-02   cluster1-01   false   Pending shutdown
2 entries were displayed.

  1. テイクオーバーが完了したかどうかを確認してください。その後、ギブバックが自動的に実行されるか、手動でギブバックを実行できます:

cluster1::>storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01   cluster1-02   false   In takeover, Auto giveback will be
                    initiated in 416 seconds
cluster1-02   cluster1-01   -     Waiting for giveback
2 entries were displayed.

  • ギブバックが自動的に開始されない場合は、手動でギブバックを実行できます:

cluster1::>storage failover giveback -ofnode <nodename>

  1. storage failover show を実行して、両方のノードが接続されていることを確認します:

cluster1::>storage failover show
 Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 true Connected to cluster1-02
cluster1-02 cluster1-01 true Connected to cluster1-01
2 entries were displayed.

  1. ギブバックが完了したら、 すべての LIF をホームポートに戻す
