Cleanup steps to remove node grac3 from a three-node cluster

First deleting the related cluster VIP:
# $GRID_HOME/bin/crsctl stop resource 
# $GRID_HOME/bin/crsctl delete resource 

Update the installer repository ( remove grac3 node )
$ ./runInstaller -updateNodeList ORACLE_HOME=/u01/app/11203/grid "CLUSTER_NODES={grac1,grac2}" CRS=TRUE

Verify current cluster nodes and delete the related cluster node
$ olsnodes
Drop grac3 from the cluster 
#  $GRID_HOME/bin/crsctl delete node -n grac3
CRS-4661: Node grac3 successfully deleted.
#  $GRID_HOME/bin/olsnodes -t -s
grac1    Active    Unpinned
grac2    Active    Unpinned

Verify node deletion with cluvfy 
$  cluvfy stage -post nodedel -n grac3
