Raw devices not visible to the Grid Installer

Version :11G Rel 2
OS : Solaris 5.10

Number of Nodes :2

We had decided to use oracle user rather than grid user as the Grid infrastructure owner as this is just a test installation.

We have done the following on Node1

# ln -s /dev/rdsk/c4defs0  ocr
# ln -s /dev/rdsk/c4defs1  vote
# ln -s /dev/rdsk/c4defs3  data1


# chown root:oinstall /dev/rdsk/c4defs0
# chown oracle:oinstall /dev/rdsk/c4defs1  -- But still owner remains root!
# chown oracle:oinstall /dev/rdsk/c4defs3

# chmod -R 777 /dev/rdsk/c4defs0
# chmod -R 777 /dev/rdsk/c4defs1
# chmod -R 777 /dev/rdsk/c4defs3


# chmod -R 777 ocr
# chmod -R 777 vote
# chmod -R 777 data1

For storage connected to node2 , we did

# ln -s /dev/rdsk/c0defs1  data2
# chmod -R 777 /dev/rdsk/c0defs1 -- for data files
# chmod -R 777 data1

During Grid installation's Disk assigning part for OCR and Voting disk,
For

Change Disk Discovery Path

I entered

/dev/rdsk/

But , it is recognising only vote and data1 devices. ocr (/dev/rdsk/c4defs0) cannot been seen . Any idea why?

Another thing i've noticed. I don't see node2's Disk device (dev/rdsk/c0defs1). Shouldn't this be listed as well at this stage?
