修改MetroCluster IP配置中的地址、网络掩码和网关

贡献者

从 ONTAP 9.10.1 开始，您可以更改 MetroCluster IP 接口的以下属性： IP 地址和掩码以及网关。您可以使用任意参数组合进行更新。

您可能需要更新这些属性，例如，如果检测到重复的 IP 地址，或者在第 3 层网络中，如果由于路由器配置更改而需要更改网关。

一次只能更改一个接口。在更新其他接口并重新建立连接之前，此接口上的流量将中断。

使用 MetroCluster configuration-settings interface modify 命令更改任何 MetroCluster IP 接口属性。

备注 这些命令用于更改特定端口的特定节点上的配置。要还原完整的网络连接，需要在其他端口上使用类似的命令。同样，网络交换机也需要更新其配置。例如，如果网关已更新，则理想情况下，它会在 HA 对的两个节点上进行更改，因为它们是相同的。此外，连接到这些节点的交换机还需要更新其网关。

使用 MetroCluster configuration-settings interface show ， MetroCluster connection check 和 MetroCluster connection show 命令验证所有接口中的所有连接是否正常工作。

修改 IP 地址，网络掩码和网关

  1. 更新单个节点和接口的 IP 地址，网络掩码和网关： MetroCluster configuration-settings interface modify

    以下命令显示如何更新 IP 地址，网络掩码和网关：

    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

(metrocluster configuration-settings interface modify)

  2. 【第 2 步】验证所有接口的所有连接是否正常工作： MetroCluster configuration-settings interface show

    以下命令显示如何验证所有接口的所有连接是否正常工作：

    cluster_A::*> metrocluster configuration-settings interface show
