准备安装NX-OS软件和参考配置文件(Reference Configuration File、RCF)

贡献者

在安装NX-OS软件和参考配置文件(Reference Configuration File、RCF)之前、请遵循此操作步骤。

关于示例

此操作步骤中的示例使用两个节点。这些节点使用两个 10GbE 集群互连端口 e0ae0b

请参见 "Hardware Universe" 验证平台上的集群端口是否正确。

备注

根据不同版本的 ONTAP ,命令输出可能会有所不同。

交换机和节点命名

此操作步骤中的示例使用以下交换机和节点命名:

  • 这两台 Cisco 交换机的名称分别为 CS1CS2

  • 节点名称为 cluster1-01cluster1-02

  • 集群 LIF 名称为 cluster1-01_clus1cluster1-01_clus2 (对于 cluster1-01 )和 cluster1-02_clus1cluster1-02_clus2 (对于 cluster1-02 )。

  • cluster1 ::: * > 提示符指示集群的名称。

关于此任务

操作步骤 要求同时使用 ONTAP 命令和 Cisco Nexus 3000 系列交换机命令;除非另有说明,否则使用 ONTAP 命令。

步骤
  1. 如果在此集群上启用了 AutoSupport ,请通过调用 AutoSupport 消息来禁止自动创建案例: ssystem node AutoSupport invoke -node * -type all -message MAINT=x h

    其中 x 是维护时段的持续时间,以小时为单位。

    备注

    AutoSupport 消息会通知技术支持此维护任务,以便在维护窗口期间禁止自动创建案例。

  2. 将权限级别更改为高级,在系统提示您继续时输入 * y * :

    set -privilege advanced

    此时将显示高级提示符(` * >` )。

  3. 显示每个集群互连交换机的每个节点中配置的集群互连接口数量:

    network device-discovery show -protocol cdp

    显示示例
    cluster1::*> network device-discovery show -protocol cdp
    
    Node/       Local  Discovered
    Protocol    Port   Device (LLDP: ChassisID)  Interface         Platform

                e0a    cs1                       Eth1/2            N3K-C3232C
                e0b    cs2                       Eth1/2            N3K-C3232C
    cluster1-01/cdp
                e0a    cs1                       Eth1/1            N3K-C3232C
                e0b    cs2                       Eth1/1            N3K-C3232C
    
    4 entries were displayed.
  4. 检查每个集群接口的管理或运行状态。

    1. 显示网络端口属性:

      network port show – IP 空间集群

    显示示例
    cluster1::*> network port show -ipspace Cluster
    
    Node: cluster1-02
                                                      Speed(Mbps) Health

    4 entries were displayed.
    1. 显示有关 LIF 的信息: network interface show - Vserver Cluster

      显示示例
      cluster1::*> network interface show -vserver Cluster
      
                  Logical            Status     Network            Current       Current Is

  5. 验证远程集群接口的连接:

ONTAP 9.9.1及更高版本

您可以使用 network interface check cluster-connectivity 命令启动集群连接的可访问性检查、然后显示详细信息:

network interface check cluster-connectivity startnetwork interface check cluster-connectivity show

cluster1::*> network interface check cluster-connectivity start

*注:*请等待几秒钟、然后再运行 `show`命令以显示详细信息。

cluster1::*> network interface check cluster-connectivity show

  1. 验证是否 auto-revert`已在所有集群Lifs上启用命令: `network interface show -vserver Cluster -fields auto-revert

    显示示例
    cluster1::*> network interface show -vserver Cluster -fields auto-revert
    
              Logical
    Vserver   Interface           Auto-revert
