配置 MetroCluster 以进行过渡

提供者 netapp-martyh netapp-ranuk 下载此页面的 PDF

要为过渡准备配置,请将新节点添加到现有 MetroCluster 配置中,然后将数据移动到新节点。

在维护之前发送自定义 AutoSupport 消息

在执行维护问题描述之前,您应发送 AutoSupport 消息以通知 NetApp 技术支持正在进行维护。告知技术支持正在进行维护,可防止他们在假定已发生中断的情况下创建案例。

必须在每个 MetroCluster 站点上执行此任务。

  1. 要防止自动生成支持案例,请发送一条 AutoSupport 消息以指示正在进行维护。

    1. 问题描述以下命令: ssystem node AutoSupport invoke -node * -type all -message MAIN=maintenance-window-in-hours

      maintenance-window-in-hours 指定维护时段的长度,最长为 72 小时。如果在该时间过后完成维护,您可以调用一条 AutoSupport 消息,指示维护期结束:ssystem node AutoSupport invoke -node * -type all -message MAINT=end

    2. 在配对集群上重复此命令。

启用过渡模式并禁用集群 HA

您必须启用 MetroCluster 过渡模式,以允许旧节点和新节点在 MetroCluster 配置中同时运行,并禁用集群 HA 。

  1. 启用过渡:

    1. 更改为高级权限级别: set -privilege advanced

    2. 启用过渡模式: MetroCluster transition enable -transition-mode non-disruptive

      注 仅在一个集群上运行此命令。
    cluster_A::*> metrocluster transition enable -transition-mode non-disruptive
    
    Warning: This command enables the start of a "non-disruptive" MetroCluster
             FC-to-IP transition. It allows the addition of hardware for another DR
             group that uses IP fabrics, and the removal of a DR group that uses FC
             fabrics. Clients will continue to access their data during a
             non-disruptive transition.
    
             Automatic unplanned switchover will also be disabled by this command.
    Do you want to continue? {y|n}: y
    
    cluster_A::*>
    1. 返回到管理权限级别: set -privilege admin

  2. 验证是否已在两个集群上启用过渡。

    cluster_A::> metrocluster transition show-mode
    Transition Mode
    
    non-disruptive
    
    cluster_A::*>
    
    
    cluster_B::*> metrocluster transition show-mode
    Transition Mode
    
    non-disruptive
    
    Cluster_B::>
  3. 禁用集群 HA 。

    注 您必须在两个集群上运行此命令。
    cluster_A::*> cluster ha modify -configured false
    
    Warning: This operation will unconfigure cluster HA. Cluster HA must be
    configured on a two-node cluster to ensure data access availability in
    the event of storage failover.
    Do you want to continue? {y|n}: y
    Notice: HA is disabled.
    
    cluster_A::*>
    
    
    cluster_B::*> cluster ha modify -configured false
    
    Warning: This operation will unconfigure cluster HA. Cluster HA must be
    configured on a two-node cluster to ensure data access availability in
    the event of storage failover.
    Do you want to continue? {y|n}: y
    Notice: HA is disabled.
    
    cluster_B::*>
  4. 验证是否已禁用集群 HA 。

    注 您必须在两个集群上运行此命令。
    cluster_A::> cluster ha show
    
    High Availability Configured: false
    Warning: Cluster HA has not been configured. Cluster HA must be configured
    on a two-node cluster to ensure data access availability in the
    event of storage failover. Use the "cluster ha modify -configured
    true" command to configure cluster HA.
    
    cluster_A::>
    
    cluster_B::> cluster ha show
    
    High Availability Configured: false
    Warning: Cluster HA has not been configured. Cluster HA must be configured
    on a two-node cluster to ensure data access availability in the
    event of storage failover. Use the "cluster ha modify -configured
    true" command to configure cluster HA.
    
    cluster_B::>

将 MetroCluster IP 节点加入集群

您必须将四个新的 MetroCluster IP 节点添加到现有 MetroCluster 配置中。

您必须在两个集群上执行此任务。

  1. 将 MetroCluster IP 节点添加到现有 MetroCluster 配置中。

    1. 将第一个 MetroCluster IP 节点( node_A_1-IP )加入现有 MetroCluster FC 配置。

      Welcome to the cluster setup wizard.
      
      You can enter the following commands at any time:
        "help" or "?" - if you want to have a question clarified,
        "back" - if you want to change previously answered questions, and
        "exit" or "quit" - if you want to quit the cluster setup wizard.
           Any changes you made before quitting will be saved.
      
      You can return to cluster setup at any time by typing "cluster setup".
      To accept a default or omit a question, do not enter a value.
      
      This system will send event messages and periodic reports to NetApp Technical
      Support. To disable this feature, enter autosupport modify -support disable
      within 24 hours.
      
      Enabling AutoSupport can significantly speed problem determination and
      resolution, should a problem occur on your system.
      For further information on AutoSupport, see:
      http://support.netapp.com/autosupport/
      
      Type yes to confirm and continue {yes}: yes
      
      Enter the node management interface port [e0M]:
      Enter the node management interface IP address: 172.17.8.93
      Enter the node management interface netmask: 255.255.254.0
      Enter the node management interface default gateway: 172.17.8.1
      A node management interface on port e0M with IP address 172.17.8.93 has been created.
      
      Use your web browser to complete cluster setup by accessing https://172.17.8.93
      
      Otherwise, press Enter to complete cluster setup using the command line
      interface:
      
      Do you want to create a new cluster or join an existing cluster? {create, join}:
      join
      
      
      Existing cluster interface configuration found:
      
      Port    MTU     IP              Netmask
      e0c     9000    169.254.148.217 255.255.0.0
      e0d     9000    169.254.144.238 255.255.0.0
      
      Do you want to use this configuration? {yes, no} [yes]: yes
      .
      .
      .
    2. 将第二个 MetroCluster IP 节点( node_A_2-IP )加入现有 MetroCluster FC 配置。

  2. 重复上述步骤,将 node_B_1-IP 和 node_B_2-IP 加入 cluster_B

配置集群间 LIF ,创建 MetroCluster 接口以及镜像根聚合

您必须创建集群对等 LIF ,并在新的 MetroCluster IP 节点上创建 MetroCluster 接口。

示例中使用的主端口是特定于平台的。您应使用特定于 MetroCluster IP 节点平台的相应主端口。

  1. 在新的 MetroCluster IP 节点上, "配置集群间 LIF"

  2. 在每个站点上,验证是否已配置集群对等: cluster peer show

    以下示例显示了 cluster_A 上的集群对等配置:

    cluster_A:> cluster peer show
    Peer Cluster Name         Cluster Serial Number Availability   Authentication
    ------------------------- --------------------- -------------- --------------
    cluster_B                 1-80-000011           Available      ok

    以下示例显示了 cluster_B 上的集群对等配置:

    cluster_B:> cluster peer show
    Peer Cluster Name         Cluster Serial Number Availability   Authentication
    ------------------------- --------------------- -------------- --------------
    cluster_A 1-80-000011 Available ok
  3. 为 MetroCluster IP 节点配置 DR 组: MetroCluster configuration-settings dr-group create -partner-cluster

    cluster_A::> metrocluster configuration-settings dr-group create -partner-cluster
    cluster_B -local-node node_A_3-IP -remote-node node_B_3-IP
    [Job 259] Job succeeded: DR Group Create is successful.
    cluster_A::>
  4. 验证是否已创建灾难恢复组。MetroCluster configuration-settings dr-group show

    cluster_A::> metrocluster configuration-settings dr-group show
    
    DR Group ID Cluster                    Node               DR Partner Node
    ----------- -------------------------- ------------------ ------------------
    2           cluster_A
                                           node_A_3-IP        node_B_3-IP
                                           node_A_4-IP        node_B_4-IP
                cluster_B
                                           node_B_3-IP        node_A_3-IP
                                           node_B_4-IP        node_A_4-IP
    
    4 entries were displayed.
    
    cluster_A::>

    您会注意到,在运行 MetroCluster configuration-settings dr-group show 命令时,旧 MetroCluster FC 节点( DR 组 1 )的 DR 组未列出。

    您可以在两个站点上使用 MetroCluster node show 命令列出所有节点。

    cluster_A::> metrocluster node show

  5. 为新加入的 MetroCluster IP 节点配置 MetroCluster IP 接口: MetroCluster configuration-settings interface create -cluster-name

    请参见 "配置和连接 MetroCluster IP 接口" 配置 IP 接口时的注意事项。注意:您可以从任一集群配置 MetroCluster IP 接口。此外,从 ONTAP 9.1.1 开始,如果使用的是第 3 层配置,则在创建 MetroCluster IP 接口时还必须指定 ` 网关` 参数。请参见链接: ./install-IP/concept_considerations_layer_3.html 。

    cluster_A::> metrocluster configuration-settings interface create -cluster-name cluster_A -home-node node_A_3-IP -home-port e1a -address 172.17.26.10 -netmask 255.255.255.0

完成 MetroCluster IP 节点的添加

您必须将新的 DR 组加入 MetroCluster 配置,并在新节点上创建镜像数据聚合。

  1. 在每个新 MetroCluster 节点上创建镜像数据聚合: storage aggregate create -aggregate aggregate-name -node node-name -diskcount no-of-disks -mirror true

    注 每个站点必须至少创建一个镜像数据聚合。建议在 MetroCluster IP 节点上为每个站点配置两个镜像数据聚合以托管 MDV 卷,但支持每个站点一个聚合(但不建议这样做)。支持 MetroCluster 的一个站点具有一个镜像数据聚合,而另一个站点具有多个镜像数据聚合。

    以下示例显示了如何在 node_A_1-new 上创建聚合。

    cluster_A::> storage aggregate create -aggregate data_a3 -node node_A_1-new -diskcount 10 -mirror t
    
    Info: The layout for aggregate "data_a3" on node "node_A_1-new" would be:

      以下示例显示了将 MDV_CRS_d6b0b313ff5611e9837100a098544e51_A 移动到 node_A_3 上聚合 data_A3 的命令和输出。
