It is possible to install ASM Grid Standalone without creating a DATA diskgroup first. It seem ohasd need to be install first

I have installed OEM grid standalone and have it working fine. However I would like to install GRID without having to create the DATA group first. In other words install ASM software using a local spfile and password file and then using sqlplus as sysasm create the first disk group and others I tried a software install of grid, but it would not let me start asm because there was no ohasd or css(something).
