Amazon Redshift databases not available after discovery
Explanation:
This error appears when the NetBackup Snapshot Manager that runs the discovery does not have access to the Redshift cluster. You can see the following error in the flexsnap logs:
Connect timeout on endpoint URL: "https://redshift.us-east-2.amazonaws.com/
Workaround:
Without access permission, the Snapshot Manager requires the inbound rules to be configured for the snapshot manager in the security group of the 'VPC endpoint of the Redshift service'.
On the AWS portal, select a cluster. Click Properties > click Network and security settings > click the virtual private cloud object > click Endpoints. Search for "redshift-endpoint" in the search field > click the VPC endpoint id > click the Security Groups tab. Click the Security Group ID > click Edit Inbound rules, and add the following for Snapshot Management servers.

Run discovery from NetBackup web UI again.
