NetBackup status code: 9896

Message: Failed to add NetBackup Snapshot Manager due to certificate generation failure.

Explanation: Certificate generation can fail due to various reasons.

Examples of certificate generation failure:

The Snapshot Manager that is located in the cloud may be unable to connect with NetBackup located on-premises inside a firewall.
Primary server and Snapshot Manager containers are not able to resolve DNS for the primary server.
The clock times for Snapshot Manager and the NetBackup server are not synchronized so the generated certificates are not valid.
Determine if the Snapshot Manager host name is already registered as a media server.

Recommended Action: Perform one or more of the following actions, depending upon the error you see:

Review the NetBackup nbemm logs to identify the exact error.
Review your network connectivity with Snapshot Manager
Resolve network issues if any, using netstat or a similar network diagnosis tool.
Determine if nbcertcmdtool is able to connect to the web service running on the NetBackup primary server to generate the NetBackup certificates.
Use the ntpdate command to synchronize clock times for the NetBackup primary server and the Snapshot Manager.
Update the DNS entries with Docker and host entries for the Snapshot Manager. Update the /cloudpoint/openv/etc/hosts file with the DNS entries. Use different network cards, IP addresses, or host names for registering the co-located media server and the Snapshot Manager. Also, if the media server and the Snapshot Manager are co-located, and the media server uses port 443, then the Snapshot Manager must use a custom SSL port.
