节点报告 StorageFCAdapterFault_Alert 出现故障或未使用的 FC 端口

适用于

• ONTAP 9
• MetroCluster
• FAS / AFF
• 以启动器模式运行的 FC 端口

问题

• 每次重新启动后，节点都会针对关闭的 FC 端口发送 AutoSupport StorageFCAdapterFault 警报：

Health Monitor process nchm: StorageFCAdapterFault_Alert[500##########]) ALERT.

• 报告的端口未使用
• MetroCluster_Node 子系统健康状况降级：

• 从 clustershell 中可以看到健康警报：

cluster::> system health alert show
               Node: node-01
           Resource: 4d
           Severity: Major
    Indication Time: Sat Aug 15 13:05:58 2020
           Suppress: false
        Acknowledge: false
     Probable Cause: FC initiator adapter 4d is at fault.
    Possible Effect: Resiliency of backend storage is compromised.
 Corrective Actions: 1. Ensure that the FC initiator link has not been tampered with.
                     2. Verify the operational status of the FC initiator
                     adapter by using the command "system node run -node
                     local -command storage show adapter"..
