Or you could just use 1 partition from each of several LUNs for your OCR & Voting. Use the rest of the space on each LUN for something else like ASM volumes.  

By the way I find it hard to believe your storage admin cannot give you less than 75G LUN's. It is probably more "rather not" than "cannot".

While that indeed should work, it has all the same use profile problems of putting all your control file copies on the same LUN.  

My advice would be to "waste" the excess space on each LUN. Further, the LUNs thus "wasted" should ideally be composed of media using disjoint components all the way down to the physical media.  

This may be a case where SSD could usefully be worked into the storage matrix, since the waste savings might well pay for the required amount of SSD.   Regards,

You can have a single LUN and have separate partitions within that LUN for OCR/Voting, and leave the rest as ASM disks.
