If the root.sh fails on a node and you try to re execute it after fixing the failure then it gives the following error:
CRS is already configured on this node for crshome=0 Cannot configure two CRS instances on the same cluster.Please deconfigure before proceeding with the configuration of new home.
In order to perform a cleanup you will need to execute the following two commands as the root user.
In all the nodes where the root.sh failed execute the following:
# perl $GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force
On the last node of the cluster execute the following as the root user:
# perl $GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode
Now you will be in a state where you can re execute the root.sh command.
