Make sure the password issued for dradmin account during Data Aggregator installation matches the password in the drinstall.properties file used to install the Data Repository vertica cluster.
Note that this is 'not' the Linux OS dradmin account password. This database user account password was specified when creating the database after the Data Repository installation. It is the 'DbPwd=' entry found in the drinstall.properties file used with dr_install.sh.
That is the password we should be using for dradmin account during DA installation.
According to the CA Performance Management documentation - Install the Data Aggregator
We can verify this on the Data Repository host by looking at the drinstall.properties file (/opt/CA/IMDataRepository_vertica8/drinstall.properties).
This was used for the original installs, and should contain the plain text password for the dradmin user - for example:
# Database name
# Database password DbPwd="<your_password>"
