After the first step of adding a new node to a cluster (cloning my CRS_HOME (cluster home of oracle RAC) and ran all scripts), the last step in the documentation was running root.sh in the new node's CRS_HOME. But the unexpected error was;
root@radbank04 # ./root.sh
"/dev/rdsk/c6t600601607D731F006596A6CD2CE9DD11d0s0" does not exist. Create it before proceeding.
Make sure that this file is shared across cluster nodes.

I am pretty sure with the raw device definitions are OK in the new node. I decided to examine the "root.sh" to see what it is running in the background. "root.sh" was consisting of two other scripts "rootinstall" and "rootconfig".
root@radbank04 # more root.sh
#!/bin/sh
/oracle/product/crs10g/install/rootinstall
/oracle/product/crs10g/install/rootconfig
I found the following part of the script in the very beginning of the rootconfig script.

Somehow (my second somehow in the 10gR2 RAC environment) crs records was showing the old ocr and voting disks. The new disks i have replaced in my existing RAC environment before was totally different. I decided to modify the rootconfig file and replace the old defined ocr and voting disks with the new ones as follows. An rerun the rootconfig file. I dont know if this action is recommended by oracle but i think this is the only change that i have in my hand.
