device-mapper-multipath多路径在存储控制器重新启动过程中丢失路径

环境


1,Red Hat Enterprise Linux 8.1

2,RHEL installed on IBM LPAR

3,IBM Virtual FC adapters managed by ibmvfc module

4,device-mapper-multipath

问题


在存储控制器重新启动期间,device-mapper-multipath多路径正在丢失控制器的路径。有一些路径并不是从受影响的存储控制器映射出来的,但是它也被标记为失败(mark as failed )

此心远送浑河岸,斟别酒,唱阳关,临别无语空长叹,酒已阑,曲未残,人初散,心长怀去后,杳鱼雁,对遥山,当时无计锁雕鞍,去后思量悔应晚,别时容易见时难!
