The message here is clear. You are specifying a directory and not a
file. Best thing to do would be to create a subdirectory under the mount
point (/u02) and then the OCR file. I may be wrong, but I think there is
a but that prevents the CRS to create file directly on the mount
point.> The intention is to have 3 small partitions for the {2} OCR and {3} CSS

Make sure the device are mounted on the same mount point on both nodes.
Better use LABEL=<volume label> instead of the device. That will prevent
problems in case of device name changing.
Also, make sure you can create a file on one node and see the same file
on the other node. The CRS install script will do the same and compare
them to make sure the devices are shared.> === Excerpt from `./runcluvfy.sh stage -post hwos -n rac01,rac02
