Description
This document would explain the details of required steps to verify Disk configuration

Steps to Follow
We will have the issue with disk labeling area and this document would address that.
Below is the normal scenario when you do the jumpstart where we don't have any problems
with disk configuration

# telnet localhost 5000
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Connecting to console "ldom1" in group "ldom1" ....
Press ~? for control options ..
