Up to 11.1 (including) you needed the voting disks and OCR disks to be the same. In 11.2 you can store them in ASM so that's not needed. I've run many Linux servers with 10g RAC on them that only had the voting/OCR identical and the data disks different. I've also installed 11.2 cluster with no regard to disk order.

What do you mean by "until we got asm headers stepped on"?
