由于交换机端SFP出现故障、VMware路径失败和FCP命令失败

适用场景

问题描述

• VMware存储路径闪烁、生成警报、

Alarm 'Cannot connect to storage' on xxx.xx.x.xx triggered by event 49104432 'Path redundancy to storage device naa.600a09803831460000000000000000 degraded. Path vmhba1:XX:XX:Xxx is down. Affected datastores: XX_NETAPP_SANxx.'

• 存储适配器端口登录连接到VMware、并在EMS中记录以下链路中断错误、

[?]  Sat Mar 23 02:16:10 +0000 [CLUSTER1-01: fct_tpd_work_thread_0: scsitarget.slifct.linkBreak:error]: Link break detected on Fibre Channel target HBA 2a with event status 1 , topology type 1, status1 0x0, status2 0x0.
[?]  Sat Mar 23 02:16:11 +0000 [CLUSTER1-01: fct_tpd_work_thread_0: scsitarget.hwpfct.linkUp:notice]: Link up on Fibre Channel target adapter 2a.

• 对于 适配器端口(主端口)的LIF、ONTAP系统管理器出现LIF操作关闭错误。
• errdump -a 在连接到存储适配器端口的交换机端口上存在"帧超时"事件。
