无法接管：NVRAM 日志未同步

适用于

• 带有外部 HA 互连电缆的 NetApp 存储系统
  • 有关 ASA、AFF 和 FAS 平台的 HA 互连程序指南的更多信息
• 除 MetroCluster IP 解决方案外

问题描述

• 检查 Active IQ 是否会影响您的系统
• 手动 storage failover show 检查报告。示例：

cluster1::> storage failover show
                Takeover
Node       Partner     Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01   cluster1-02   true    Connected to cluster1-02
cluster1-02   cluster1-01   false   Connected to cluster1-01, Takeover is
                    not possible: NVRAM log not
                    synchronized
2 entries were displayed.

• 显示"Reason Takeover not Possible"字段将显示以下内容。示例：

cluster1::> storage failover show -fields reason
node       reason
-------------- ------
cluster1-01   -
cluster1-02  "NVRAM log not synchronized"

• 无法手动接管。示例：

cluster1::> storage failover show -node cluster1-n1 -fields possible
node         possible
------------ --------
cluster1-01 false

• 在 Fabric MetroCluster 环境中，可以报告以下检查输出。示例： 

cluster1::> metrocluster check node show -instance 
               Node Name: cluster1-01
             Type of Check: ha-mirroring-op-state
                 Cluster Name: cluster 1
          Result of the Check: warning
Additional Information/Recovery Steps: Node's HA mirroring is not online. Verify the HA mirroring link status with the "metrocluster interconnect show" command, then bring the HA mirroring online with the "storage failover modify -node <node> -enabled true" command.

• ONTAP 事件消息系统 (EMS) 正在报告。示例：

... [cluster1-01: statd: cf.takeover.disabled:alert]: HA mode, but takeover of partner is disabled due to reason : unsynchronized log.
