Having not done this yet personally and having only read about it, take this
with a grain of salt and of course read the manuals. My thoughts would trend
toward adding new OCR and voting disks in the desired locations and then
later removing the ones to be removed. I believe that without adding
"mirrors" (which I wish they called plexes or image copies, because hey,
they are really not backward images) you have to have an outage to move
them.
I believe the commands you want are ocrconfig and crsctl.
I think I've seen the details in K Gopalalakrishnan's book on RAC, and in
the Julian Dyke/Steve Shaw book as well if you need something more succinct
and clear than the manuals.
Good luck,

Subject: RAC on Linux moving OCR and Voting disk to another SAN
We are implementing a more powerful SAN array, and need to move a 10g
RAC cluster to this new storage. We know how to move the ASM storage
without any downtime. However, we cannot figure out if it is possible
to move the OCR and Voting disk with no downtime. Does anybody have any
suggestions ?
