Problem installing 2nd HDD

I have a dedicated server and have installed 2nd hdd. It has been successfully mounted to /home1. My first HDD is mounted to /home. My purpose is to use both HDD for hosting. The problem is whenever I create a new account it is always on /home. How do I use /home and /home1 with the WHM?

 

I found the following info

Default Home Directory*
Enter the location where you wish for new users' home directories to be created. By default all directories matching the "Home Directory Prefix" are checked for available disk space and the directory with the most free space will be used.

Example: /home

Home Directory Prefix
Additional home directories matching the following value will also be used for new home directory creations. This option only takes one value. A blank value disables this feature

It checks the directory which is most free and only one entry is valid I think and that is /home. But I want to use /home1 also.

 

Thanks for the info. But could you please explain how or can you give me a link where I can get these infos:
1. Adding /home1 to WHM
2. Transferring clients
3. Using /home for new clients.
