由于Fabric MetroCluster 系统中存在多个挡板、FC端口脱机

适用场景

问题描述

• FC主机适配器开始在节点上摆动并脱机：

[Node-01: slifc_intrd: fci.link.break:error]: Link break detected on Fibre Channel adapter 2b.
[Node-01: slifc_asyncd_0: fci.adapter.link.online:info]: Fibre Channel adapter 2b link online.
[Node-01: slifc_intrd: fci.link.break:error]: Link break detected on Fibre Channel adapter 2b.
[Node-01: slifc_timeout_0: fci.link.error:error]: Could not recover link on Fibre Channel adapter 2b after 30 seconds. Taking the adapter offline.
[Node-01: slifc_intrd: fci.link.break:error]: Link break detected on Fibre Channel adapter 2b.
[Node-01: lhm_main: callhome.fc.al.link:alert]: Call home for FC-AL LINK_FAILURE (2b)

• 在sysconfig -a输出中、端口状态显示脱机：

::> system node run -node <node> sysconfig -a

slot 2: FC Host Adapter 2b (Emulex XE201 rev. 48, <OFFLINE (hard)>)

• 在连接到节点上FC端口的交换机端口上、可能会出现大量链路故障：
