由于FC链路故障、导致"主机端连接冗余丢失"

• NetApp E 系列
• 光纤通道连接

• 系统生成警报报告、并在控制器 重新启动后持久保留：

• 错误 RECOVERY-GURU-PROCEDURES.HTML：

ALB_HOST_REDUNDANCY_LOST-Recovery Failure Type Code: 475

• 错误 Major Event Logs PARSER：

Loss of host-side connection redundancy detected - Host hostname <--CRITICAL

Volume not on preferred path due to AVT/RDAC failover - Shelf XX, Bay X <--CRITICAL

• 一个控制器的端口0a和0b上的FC链路已关闭：

         Channel:                      1
         Port:                        0a, 0a
