The installation works perfectly until we are running the root.sh script. It does most of what it needs to but fails when trying to rmtcopy. "Failed to rmtcopy "/tmp/fileYX17Oj" to "/u1/oracle/product/11.2.0/grid/gpnp/manifest.txt" for nodes ..." All the the information we have seen about setting up "passwordless" ssh is for the owner of the GridInrastructure. This passes all the tests and the "Remote System Operations" part of the install works. It is only root.sh where we are having problems. Do you have to setup root in the same was as the grid infrastructure owner? Ian A.
