Non-stop adding host disks to virtual machines (for example, VMware Workstation)

I. Previous disk condition not added

Second, view the host bus number

[Email protected] ~]# ls/sys/class/scsi_host/host0 host1 host2

Third, add a new hard drive (take VMware workstation as an example)

Four, rescan SCSI bus add disk
