vsanDiskFaultInjection.pyc script for test disk failure

In the official documentation of VSAN, it talk about a fault injection script for failure testing.

This script, named vsanDiskFaultInjection.pyc, should be in /usr/lib/vmware/vsan/bin/ directory but isn't.

Am i the lonly or somebody else is in the same state ? 

Is there a reason for Dell to get out the script ?

How can i simulate a disk failure ? 

EDIT: i finally find this script in the good directory. I don't understand why i didn't yesterday !!!
