Thank you answering the question.

My pex command line is as follow:

In the emergency shell

[root at mcptest ~]# cat /proc/cmdline
ksdevice=bootif text BOOTIF=eth0 firstboot storage_init=/dev/sda lang=

We are installing it to the hard disk , and the previous installation is 
RHEVH 6.3. During the installation,
before performing the disk format, it checks that there is a existing 
HostVG on the disk, so it stops installing.
