The dr_install.sh is using a non-root user when trying to ssh to the data repository nodes but we are logged in and running the commands as the root user.
DX NetOps Performance Managment: All versions.
The customer was not using sudo su - to login to the root user. So it was using the user the customer logged into the system with instead of the root user.
When using sudo to login to the root user, use sudo su - to login. This will use the root users environment and when you kick off the dr_install it will ssh using the root user instead of the user you login user credentials.
