11g R2 Deinstall of Grid Infrastructure Cluster

从11gR2开始，Grid Infrastructure Cluster 可以用脚本卸载了，很方便，卸载的也很干净，给安装rac的同学节约了很多宝贵的时间。so cool .

Deinstall of Grid Infrastructure Cluster:

Case 1: "root.sh" never ran on this cluster, then as grid user, execute $GRID_HOME/deinstall/deinstall

Case 2: "root.sh" already ran, then follow the step below - please keep in mind that you will need wait till each step finishes successfully before move to next one:（以下几个脚本都以root用户执行）

        Step 1: As root, run "$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force" on all node, except the last one. 


        Step 2: As root, run "$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode" on last node. This command will zero out OCR and VD disk also. 

        Step 3: As grid user, run "$GRID_HOME/deinstall/deinstall" on any node.
