I install the RAC in virtual environment (Grid Infrastructure version 12.2), and performing the second node, I use udev mapping defines two pieces of asm disk:/dev/asm - diskb and/dev/asm - diskc, all show the two pieces of hard disk; But root. Sh occsd trace after log in, according to the root. Sh scripts is not recognize these two pieces of hard disk (asm - diskb when I install designated as voting disk) :

I was in the first RAC node defines the same hard disk, but root. Sh is the end of the normal installation,
I redefine the second node of the two pieces of hard disk, or get node 1 two pieces of hard disk directly, not all,
And I found A phenomenon: as long as it is the second node is such result, such as node A and node B, no matter who they are as the installation of the second node, will face the problem,

Have technical bosses, whether to have a look at where the problem is,
