其他技术问题
1

虚拟机安装OpenEuler 22.03-LTS, 虚拟机新增一块硬盘，未重启系统，
无法扫描磁盘：

[root@EulerDocker ~]# echo “—” > /sys/class/scsi_host/host0/scan
-bash: echo: write error: Invalid argument

[root@EulerDocker ~]# echo “—” > /sys/class/scsi_host/host0/scan
-bash: echo: write error: Invalid argument
[root@EulerDocker ~]# echo “—” > /sys/class/scsi_host/host1/scan
-bash: echo: write error: Invalid argument
[root@EulerDocker ~]# echo “—” > /sys/class/scsi_host/host2/scan
-bash: echo: write error: Invalid argument
[root@EulerDocker ~]# ls /sys/class/scsi_host/
host0 host1 host2

虚拟机新增硬盘算热插拔吗

应该算吧
