在更換 MetroCluster IP 交換器、變更 RCF 或更新韌體之前,請先移動叢集 LIF

貢獻者 netapp-aoife

當您更換 MetroCluster IP 交換器或變更交換器韌體或參考組態檔案 (RCF) 時,需要將叢集 LIF 移至合作夥伴交換器,以實現不間斷的叢集作業。

關於這項工作
  • 在升級或降級交換器韌體、更換交換器 RCF 或更換 IP 交換器之前,必須執行此工作。

    註 如果是第一次設定交換器,則可以跳過此工作,除非您要更換交換器。
  • 此工作需要您同時使用 ONTAP 命令和交換器命令;除非另有說明,否則皆使用 ONTAP 命令。

  • 在本程序的範例中,您正在升級 IP_switch_A_1,因此您需要將叢集 LIF 移轉至 IP_switch_A_2。

  • 本程序中的命令輸出範例顯示 Cisco 交換器的詳細資訊。輸出結果可能因交換器型號和廠商而異。

  2. 檢查每個叢集連接埠的管理和運作狀態。

    1. 確認叢集所有連接埠均已啟動且狀態正常:

      network port show -role cluster

      顯示範例
      cluster_A::*> network port show -role cluster
      
      Node: node_A_1
                                                                             Ignore

      4 entries were displayed.
    2. 確認所有叢集介面(LIF)都位於主連接埠上:

      network interface show -role cluster

      顯示範例
      cluster_A::*> network interface show -role cluster
                  Logical        Status     Network            Current       Current Is
      Vserver     Interface      Admin/Oper Address/Mask       Node          Port    Home
      ----------- -------------- ---------- ------------------ ------------- ------- ----
      Cluster

                  node_A_2_clus2 up/up      101.101.101.97/18  node_A_2      e4b     true
      4 entries were displayed.
      
      cluster_A::*>
    3. 確認叢集顯示兩個叢集交換器的資訊:

      system switch ethernet show -is-monitoring-enabled-operational true

    顯示範例
    cluster_A::*> system switch ethernet show -is-monitoring-enabled-operational true
    Switch                      Type               Address          Model
    --------------------------- ------------------ ---------------- ---------------

        Version Source: CDP/ISDP
    
    2 entries were displayed.
    
    cluster_A::*>
  3. 停用叢集 LIF 的自動還原功能。叢集 LIF 容錯移轉到合作夥伴叢集交換器,並在您對目標交換器執行升級程序時保持在該交換器上:

    註 如果您要升級第二個架構,則可以跳過此步驟並轉到步驟4.

    network interface modify -vserver Cluster -lif * -auto-revert false

    顯示範例
    cluster_A::*> network interface modify -vserver Cluster -lif * -auto-revert false
    
    Warning: Disabling the auto-revert feature of the cluster logical interface may
             effect the availability of your cluster network. Are you sure you want

    Warning: Changes to a cluster LIF can affect the health of the Cluster. Are you

  4. 在叢集交換器 IP_switch_A1 上,關閉連接到節點叢集連接埠的連接埠。

    1. 顯示叢集介面:

    2. 關閉叢集介面連接埠:

      sudo python3 <RCF_name> runCmd swp1 state down
  5. 驗證叢集 LIF 是否已移轉到叢集交換器 IP_switch_A2 上託管的連接埠。這可能需要幾秒鐘。

    network interface show -role cluster

    顯示範例
    cluster_A::*> network interface show -role cluster

                node_A_1_clus2 up/up      101.101.101.93/18  node_A_1      e4b     true
                node_A_2_clus1 up/up      101.101.101.96/18  node_A_2      e4b     false
                node_A_2_clus2 up/up      101.101.101.97/18  node_A_2      e4b     true
    4 entries were displayed.
  6. 驗證叢集是否正常:

    「叢集展示」

    顯示範例
    cluster_A::*> cluster show
    Node                 Health  Eligibility   Epsilon
    -------------------- ------- ------------  ------------
    node_A_1             true    true          false
    node_A_2             true    true          false
    2 entries were displayed.
完成後

叢集 LIF 移轉到合作夥伴交換器後,您可以依照交換器廠商的標準組態程序完成升級至目標韌體或 RCF 版本:

註 在第一個架構中設定交換器後,必須重複上述步驟,將叢集 LIF 移轉至第二個架構。
