在 MetroCluster IP 配置中的替代控制器模块上启动到 ONTAP

提供者 netapp-thomi netapp-pcarriga

您必须将灾难站点上的替代节点启动到 ONTAP 操作系统。

此任务从处于维护模式的灾难站点上的节点开始。

步骤
  1. 在一个替代节点上,退出到 LOADER 提示符: halt

  2. 显示启动菜单: boot_ontap menu

  3. 从启动菜单中,选择选项 6 * 从备份配置更新闪存 * 。

    系统启动两次。系统提示您继续时,您应回答 yes 。在第二次启动后,当系统 ID 不匹配时,您应响应 y

    注 如果未清除已用替代控制器模块的 NVRAM 内容,则可能会看到以下崩溃消息: panic : NVRAM 内容无效 …​ 如果发生这种情况,请将系统重新启动到 ONTAP 提示符(boot_ontap menu )。然后,您需要执行根恢复。请联系技术支持以获得帮助。
    • 确认继续提示:

      Selection (1-9)? 6
      
      This will replace all flash-based configuration with the last backup to
      disks. Are you sure you want to continue?: yes
    • 系统 ID 不匹配提示:

      WARNING: System ID mismatch. This usually occurs when replacing a boot device or NVRAM cards!
      Override system ID? {y|n} y
  4. 在正常运行的站点中,验证是否已将正确的配对系统 ID 应用于节点:

    MetroCluster node show -fields node-systemID , ha-partner-systemID , dr-partner-systemID , dr-auxiliary-systemID

    在此示例中,输出中应显示以下新的系统 ID :

    • node_A_1 : 1574774970

    • node_A_2 : 1574774991

    "ha-partner-systemID" 列应显示新的系统 ID 。

    metrocluster node show -fields node-systemid,ha-partner-systemid,dr-partner-systemid,dr-auxiliary-systemid
    
    dr-group-id cluster    node      node-systemid ha-partner-systemid dr-partner-systemid dr-auxiliary-systemid
    ----------- ---------- --------  ------------- ------ ------------ ------ ------------ ------ --------------
    1           Cluster_A  Node_A_1  1574774970    1574774991          4068741254          4068741256
    1           Cluster_A  Node_A_2  1574774991    1574774970          4068741256          4068741254
    1           Cluster_B  Node_B_1  -             -                   -                   -
    1           Cluster_B  Node_B_2  -             -                   -                   -
    4 entries were displayed.
  5. 如果未正确设置配对系统 ID ,则必须手动设置正确的值:

    1. 暂停并显示节点上的 LOADER 提示符。

    2. 验证 partner-sysID bootarg 的当前值:

      printenv

    3. 将此值设置为正确的配对系统 ID :

      setenv partner-sysid partner-sysID

    4. 启动节点:

      boot_ontap

    5. 如有必要,在另一节点上重复这些子步骤。

  6. 确认灾难站点上的替代节点已做好切回准备:

    MetroCluster node show

    替代节点应处于等待切回恢复模式。如果它们处于正常模式,则可以重新启动替代节点。启动后,节点应处于等待切回恢复模式。

    以下示例显示替代节点已做好切回准备:

    cluster_B::> metrocluster node show
    DR                               Configuration  DR
    Group Cluster Node               State          Mirroring Mode
    ----- ------- ------------------ -------------- --------- --------------------
    1     cluster_B
                  node_B_1           configured     enabled   switchover completed
                  node_B_2           configured     enabled   switchover completed
          cluster_A
                  node_A_1           configured     enabled   waiting for switchback recovery
                  node_A_2           configured     enabled   waiting for switchback recovery
    4 entries were displayed.
    
    cluster_B::>
  7. 验证 MetroCluster 连接配置设置:

    MetroCluster configuration-settings connection show

    配置状态应指示已完成。

    cluster_B::*> metrocluster configuration-settings connection show
    DR                    Source          Destination
    Group Cluster Node    Network Address Network Address Partner Type Config State
    ----- ------- ------- --------------- --------------- ------------ ------------
