I hope you meant non-common path but physical volumes behind are the same.
As already mentioned, you don't have to take care about same names for
ASM disks but you do want same consistent paths for OCR and VD.

cluvfy has a bug that it can only work with standard SCSI disks and
something like multipathed disks and etc don't work. There is Metalink
note about it - 358617.1.

I personally never bother with cluvfy for long time and just have the
list of things I need to do before installation.
