在 MetroCluster IP 配置中的替换控制器模块上引导至 ONTAP

必须将灾难站点的替换节点引导至 ONTAP 操作系统。

关于本任务

此任务在处于维护模式下从灾难站点的节点开始。

在其中一个替换节点上，退出到装入程序提示符处：halt
显示引导菜单：boot_ontap menu
从引导菜单中，选择选项 6：Update flash from backup config（从备份配置中更新闪存）。
系统将引导两次。在提示继续时应回答 yes。第二次引导后，在提示系统标识不匹配时应回答
y。
注
如果未清除使用过的替换控制器模块的 NVRAM 内容，则可能会显示混乱消息：PANIC: NVRAM contents are invalid...。
如果发生这种情况，请再次将系统引导至 ONTAP 提示符位置（boot_ontap menu）。然后，您需要执行根恢复。请联系技术支持以获取帮助。
示例
确认是否继续提示：
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
系统标识不匹配提示：
WARNING: System ID mismatch. This usually occurs when replacing a boot device or NVRAM cards! Override system ID? {y|n} y

从幸存站点上验证是否已将正确的伙伴系统标识应用于节点：metrocluster node show -fields node-systemid,ha-partner-systemid,dr-partner-systemid,dr-auxiliary-systemid

示例

在此示例中，以下新系统标识应出现在输出中：

Node_A_1：1574774970
Node_A_2：1574774991

ha-partner-systemid 列应显示新的系统标识。

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.

如果未正确设置伙伴系统标识，必须手动设置正确的值：
1. 在节点上停止并显示装入程序提示符。
2. 验证 partner-sysID bootarg 的当前值：printenv
3. 将值设置为正确的伙伴系统标识：setenv partner-sysid partner-sysID
4. 引导节点：boot_ontap
5. 如有必要，对另一个节点重复执行上述子步骤。

确认灾难站点的替换节点已准备好进行切回：metrocluster node show

替换节点应处于 waiting for switchback recovery 模式。如果它们处于 normal 模式，可以重新启动替换节点。进行该引导后，节点应该会处于 waiting for switchback recovery 模式。

示例

以下示例显示替换节点已准备好进行切回：

cluster_B::> metrocluster node show
DR                               Configuration  DR

              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.

验证 MetroCluster 连接配置设置：metrocluster configuration-settings connection show

示例

配置状态应显示 completed。
