Jayaraj,
Look for ocrconfig/crsctl commands .. It is simple (and online if you
are 11g and need to shutdown the clusterware otherwise) . You didn't
say the version. So I am bit careful here and assume it is 10g
Here are the steps..
Shutdown the clusterware..
For OCR migration
#ocrconfig -replace ocr <new_location>
#ocrconfig - replace ocrmirror <newlocation>
For Votedisk
#crsctl query css votedisk
<get the votedisks>
#crsctl delete css votedisk <first votedisk>
#crsctl add css votedisk <first_new_vote_disk>
Repeat the steps.
Check the clusterware admin guide or metalink for exact syntax. But
the steps are similar to the above.
