RE: Oracle 10.2 - Sun solaris 10 - while installing CRS

finally I found the solution, which get me out of the woods. For all
CRS/ASM/RAC on raw devise, enthusiasts here is what I did.
 

Cause

The reason we were not able to initialize the ocr voting disk is when
the device was created, it didn't skip the first 1MB to avoid
overwriting the disk VTOC. 

Solution


To implement the solution, please execute the following steps:


Note: The following steps is for Sun Solaris


1. Determine which disk devices will be used store the OCR and voting
disk file. Use the format
command to list the devices, and select the appropriate device. Create a
120 Mb partition and
label the disk. Note, the disk partition to be used must skip the first
1Mb to avoid overwriting
the disk VTOC.
Repeat this step for the voting disk, using 20Mb for the disk device.

2. Make sure the other nodes can see those devices. If the other nodes
see those devices at a
different path, then common symbolic links or mknod command must be used
to point to the same
location.

3. Initialize the devices using dd.
dd if=/dev/zero of=/dev/rdsk/c3t4d12s6 bs=125829120 \
count=1
dd if=/dev/zero of=/dev/rdsk/c3t4d15s6 bs=20971520 \
count=1

4. Change the permissions and ownership on the two devices.
OCR disk device
chown root:dba /dev/rdsk/c3t4d12s6
chmod 660 /dev/rdsk/c3t4d12s6
Voting disk
chown oracle:dba /dev/rdsk/c3t4d15s6
chmod 660 /dev/rdsk/c3t4d15s6

See Note 293819.1
