How to pass SCSI command to hard disk on Vmware ESXi (6.0)

Hello,

I want to develop a application to pass SCSI command to hard disk.

In linux, when pass SCSI or other command to device, we just use ioctl() function to do it.

But hard disk device node was not showed as /dev/sdx on VMware ESXi just like linux does,

So How can I pass these command to device on VMware ESXi just like doing it on Linux.
