Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

Remove files from the OCR and Voting disk directories. For our example:

# rm /ocrvote/ocr

# rm /ocrvote/vote-disk

If OCR and Voting disk storage are on raw volumes, use command resembling:

# dd if=/dev/zero of=/dev/vx/rdsk/ocrvotedg/ocrvol bs=8192 \

count=18000

# dd if=/dev/zero of=/dev/vx/rdsk/ocrvotedg/votvol bs=8192 \

count=3000
