如何执行接管/回馈
适用于
- ONTAP 9
- 存储接管/交还
说明
- 本文介绍如何对 ONTAP 集群中的节点执行接管和回馈
- 如果需要关闭集群中的一个或多个节点，请按照 正常关闭并启动存储系统解决方法指南进行操作
操作步骤
System Manager
- 使用 System Manager 对节点执行重新启动
- 当节点重新启动时，HA 伙伴自动执行接管
- 重新启动完成后，可以通过 System Manager 执行回馈选项
ONTAP 命令行界面
cluster1::>storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 true Connected to cluster1-02
cluster1-02 cluster1-01 true Connected to cluster1-01
2 entries were displayed.
- 如果该
Possible字段为 false，请在继续之前 启用存储故障转移 。 - 开始接管要接管的节点：
cluster1::>storage failover takeover -ofnode <nodename>
以下示例导致名为 cluster1-02 的节点被接管
cluster1::>storage failover takeover -ofnode cluster1-02
Warning: A takeover will be initiated. Once the partner node reboots, a giveback will be automatically initiated. Do you want to continue? {y|n}: y
- 检查接管进度：
cluster1::>storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 true Takeover scheduled. cluster1-02
has relocated its SFO aggregates in
preparation of takeover.
cluster1-02 cluster1-01 false Pending shutdown
2 entries were displayed.
- 检查接管是否已完成，然后回馈将自动执行，或者您可以手动回馈：
cluster1::>storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 false In takeover, Auto giveback will be
initiated in 416 seconds
cluster1-02 cluster1-01 - Waiting for giveback
2 entries were displayed.
- 如果交还未自动启动，则可以执行手动交还：
cluster1::>storage failover giveback -ofnode <nodename>
- 运行 storage failover show 以确保两个节点均已连接：
cluster1::>storage failover show
Takeover Node Partner Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01 cluster1-02 true Connected to cluster1-02
cluster1-02 cluster1-01 true Connected to cluster1-01
2 entries were displayed.
- 交还完成后，可能需要将所有 LIF 还原到其主端口 [1]
