In 11gR2, deinstall is the recommended tool to deinstall an Oracle Clusterware(Grid Infrastructure) home, however it does not apply to certain scenarios or fails in some cases. 

This notes provides manual instruction to remove a clusterware home (CRS or Grid Infrastructure).

Solution

To remove a home, as clusterware user execute the following on any node:

export ORACLE_HOME=

## detach ORACLE_HOME
$ORACLE_HOME/oui/bin/runInstaller -detachHome -silent ORACLE_HOME=$ORACLE_HOME

## confirm $ORACLE_HOME is removed from central inventory:
$ORACLE_HOME/OPatch/opatch lsinventory -all   

## remove files in ORACLE_HOME manually on all nodes
/bin/rm -rf $ORACLE_HOME

unset ORACLE_HOME

If it fails for any reason, as clusterware user execute the following on all nodes:
export ORACLE_HOME=

## detach ORACLE_HOME
$ORACLE_HOME/oui/bin/runInstaller -detachHome -silent -local ORACLE_HOME=$ORACLE_HOME

## confirm $ORACLE_HOME is removed from central inventory:
