在aarch64上下载镜像 https://mirrors.openanolis.cn/anolis/7.9/isos/GA/aarch64/AnolisOS-7.9-GA-aarch64-dvd.iso后安装虚拟机，未复现。
操作步骤：
1、下载上述链接处镜像，安装虚拟机。
2、mpathconf  --enable（生成配置文件）
3、systemctl start multipathd.service 
4、systemctl status multipathd.service

如下
[root@localhost ~]# mpathconf  --enable
[root@localhost ~]# systemctl start multipathd.service 
Display all 199 possibilities? (y or n)
[root@localhost ~]# systemctl start multipathd.service 
[root@localhost ~]# systemctl status multipathd.service

对比后发现，bug中uname -a输出的内核版本与anolis7.9默认版本有差异，请确认该环境是否是用户修改后的环境。

系统环境有变动kernel版本不是Anolis OS GA版本对应版本，正常测试未复现该问题。
