修改 MetroCluster IP 介面的內容

貢獻者
PDF

從ONTAP 版本號《E59.10.1》開始、您可以變更MetroCluster 下列功能：IP位址和遮罩、以及閘道。您可以使用任何參數組合來更新。

例如、如果偵測到重複的IP位址、或是因為路由器組態變更而需要變更第3層網路的閘道、您可能需要更新這些內容。

修改IP位址、網路遮罩和閘道

您所遵循的程序取決於您是使用 ONTAP 系統管理員還是使用 CLI 。

系統管理員

使用 System Manager 修改 IP 位址、網路遮罩和閘道內容。

步驟

更新每個節點和介面的 IP 位址、網路遮罩和閘道。

CLI

使用 CLI 修改 IP 位址、網路遮罩和閘道內容。

關於這項工作

  • 一次只能變更一個介面。在更新其他介面並重新建立連線之前、該介面會造成流量中斷。

  • 使用「MetroCluster 靜態組態設定介面modify」命令來變更MetroCluster 任何的任何靜態IP介面屬性。

    註 這些命令會變更特定連接埠之特定節點的組態。若要還原完整的網路連線能力、其他連接埠也需要類似的命令。同樣地、網路交換器也需要更新其組態。例如、如果閘道已更新、則理想情況下會在HA配對的兩個節點上變更閘道、因為它們相同。連接到這些節點的交換器也需要更新其閘道。

  • 使用 metrocluster configuration-settings interface show、 metrocluster connection check`和 `metrocluster connection show 命令來驗證所有的連線功能是否都能在所有介面中運作。

步驟

  1. 更新單一節點和介面的IP位址、網路遮罩和閘道：MetroCluster 「修改組態設定介面」

    下列命令顯示如何更新IP位址、網路遮罩和閘道：

    cluster_A::* metrocluster configuration-settings interface modify -cluster-name cluster_A -home-node node_A_1 -home-port e0a-10 -address 192.168.12.101 -gateway 192.168.12.1 -netmask 255.255.254.0
(metrocluster configuration-settings interface modify)
Warning: This operation will disconnect and reconnect iSCSI and RDMA connections used for DR protection through port “e0a-10”. Partner nodes may need modifications for port “e0a-10” in order to completely establish network connectivity.
Do you want to continue?" yes

cluster_A::*> metrocluster configuration-settings interface modify -cluster-name cluster_A -home-node node_A_2 -home-port e0a-10 -address 192.168.12.201 -gateway 192.168.12.1 -netmask 255.255.254.0
(metrocluster configuration-settings interface modify)

Do you want to continue?" yes
[Job 28] Job succeeded: Interface Modify is successful

  2. 確認所有連線功能都適用於所有介面：MetroCluster 「介紹組態設定介面」

    下列命令說明如何驗證所有連線功能是否適用於所有介面：
