I think one of our major concerns is to prevent a failure due to disk issues on the old SAN. If I add mirrors to the new SAN for OCR and Voting disk (VD), we can then worry about removing the old ocr and vd during a maintenance window at our leisure.

I see K Gopalakrishnan has already responded and added a version
warning. He
even spelled his own name correctly. Sorry about the extra "la" in my
earlier post.

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,

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
