MetroCluster 中的 FC 启动程序适配器脱机

适用场景

• ONTAP 9
• 光纤 MetroCluster
• FAS/AFA系统

问题描述

• 在光纤MetroCluster配置中、FC适配器已脱机：

cluster1::> system node run -node node1 -command sysconfig -a

slot 1: FC Host Adapter 1a (Emulex XE501 rev. 1, <OFFLINE (hard)>)
         Board name:     111-03648
         Serial Number:    FP12345678
         Firmware rev:    11.4.277.0
         Host Port Id:    N/A
         FC Node Name:    2:000:00109b:ea9206
         FC Port Name:    1:000:00109b:ea9206
         Link Data Rate:   N/A

• 事件日志中报告以下警报：

[Node-01: nchmd: hm.alert.raised:alert]: Alert Id = StorageFCAdapterFault_Alert , Alerting Resource = 10000010XXXX206 raised by monitor node-connect

• MetroCluster节点运行状况降级、原因是：

cluster1::> system health subsystem show
Subsystem      Health
----------------- ------------------
SAS-connect     ok
Environment     ok
Memory       ok
Service-Processor ok
Switch-Health    ok
CIFS-NDO      ok
Motherboard     ok
IO         ok
MetroCluster    ok
MetroCluster_Node degraded
FHM-Switch     ok
FHM-Bridge     ok
SAS-connect_Cluster ok
13 entries were displayed.

• 节点配置可能会更改为"多路径"、而不是"四路径"配置。
• 从交换机日志中可以观察到、连接到受影响FC端口的交换机端口报告 No_Sync 或 No_Light:

MCC-sw2:admin>switchshow
switchName: MCC-sw2
switchType:  181.0
switchState: Online
switchMode:  Native

Index Port Address  Media Speed   State     Proto
==================================================
  8   8   070800   id   32G   No_Sync   FC

• 已重新拔插节点FC端口和交换机端口之间的缆线。
