Beware, You can not move voting disk online till 10204(due to a bug!) and this requires cluster downtime (and also a -force option). However, OCR can be migrated online as you mentioned.

Thinking out loud, add/remove voting disk by using:

 crsctl add css votedisk <path> - adds a new voting disk  crsctl delete css votedisk <path> - removes a voting disk

for CRS:

use ocrconfig to add the new ocr disks and remove the old ones?

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 ?
