Grid Infrastructure Root Script Failure

Issue:

Grid Infrastructure root script fails.

Description:

After Grid Infrastructure bits are laid down, the next essential step is Grid Infrastructure root script execution. This is the most process intensive phase of your deployment procedure. During this process, the GI stack configures itself and ensures all subsystems are alive and active. The root script may fail to run.

Solution:

Visit each node that reported error and run the following command on n-1 nodes:
```
$GI_ORACLE_HOME/crs/install/rootcrs.pl -deconfig -force
```
If the root script did not run successfully on any of the nodes, pass the -lastNode switch on nth node (conditionally) to the final invocation as shown below.
```
$GI_ORACLE_HOME/crs/install/rootcrs.pl -deconfig -force -lastNode
```
Retry the failed step from the Procedure Activity page.
