I sometimes disable the Fibre Channel adapters by running pcmpath set adapter offline, define or check the WWNs manually, and then turn the adapter back on.
我有时会通过运行pcmpath set adapter offline禁用光纤通道适配器并手动定义或检查WWN,然后再重新开启适配器。

And you can pull a Fibre Channel cable between your servers and switch to simulate a broken FC cable; you can disable one switch port of your server/storage to simulate a switch failure.
您可以在服务器之间拉起 Fibre Channel 电缆和交换机,以模拟坏掉的 FC 电缆;您可以禁用服务器/存储器的某个交换机端口,以模拟交换机失败。
