Issue:
Data Repository will not start and prompts for the dradmin user's password.
Environment:
CA Performance Management 3.5
Cause:
If passwordless ssh is misconfigured, or there is an issue with the dradmin account on any of the nodes (such as the account being expired)
you will not be able to start the Vertica database until resolved.
Resolution:
The following outlines how to check and set up passwordless ssh between nodes:

https://docops.ca.com/ca-performance-management/3-5/en/installing/prepare-to-install-the-data-repository#PreparetoInstalltheDataRepository-(Optional)SetUpPasswordlessSSH

Note this should be done for the root user and dradmin user.

For each node verify it can SSH to itself and all the other nodes in the Data Repository cluster, without any password prompts.

Example:

ssh dradmin@localhost ls
ssh dradmin@node2 ls
ssh dradmin@node3 ls
....

Do this from all nodes to the other nodes as the dradmin.
