FlexArray 在适配器上显示连续的错误状态“ Device asyncd State 停滞”

适用于

• E 系列
• FlexArray/V-Series
• 光纤连接

问题

在架构连接配置中更换用于后端阵列 LUN 访问的 HBA 后、 ONTAP 可能会显示连续挂起状态、并且无法访问后端 E 系列阵列。此问题 DOEN 不适用于直接连接配置。 

以下错误将打印到 ONTAP 控制台：

Jun 07 13:39:03 [ClusterA-01:fci.adapter.error:notice]: Fibre Channel adapter driver encountered error "Device asyncd state stalled" on adapter 2b.

当查看当时 E 系列控制器的 DQ 跟踪时、每次 FC 登录尝试都会报告旧启动器的注销并报告重复的端口 ID ：
