I am doing a fresh installed on a new DR host then performed a dr_validate step but it was failed because the validation found the existing Vertica package and required the database to be up in order to verify the db connection.
".......
Verifying that sshd AllowTcpForwarding is enabled. ......................[ OK ]

Existing Vertica package discovered - need to perform database connectivity testing.
dradmin@hostname's password:

Database must be up and running to verify database connection properties in drinstall.properties! [FAIL]
Please start your database via admintools and re-execute this script.

Release : 20.2
Component : IM Reporting / Admin / Configuration
Vertica was uninstalled, but elements of the installation still remain
remove /home/dradmin folder
also remove any other folders related to Vertica, such as data and catalog folders
You may also need to run yum remove vertica-10.1.1-20.x86_64 and then re-run the dr_validate script.
