About discovery of SAP HANA objects
NetBackup discovery runs regularly and gathers information for instances in your environment. The data expires after one hour. The NetBackup Discovery Service (nbdisco) runs "shallow" discovery every 8 hours for instances on the clients for that primary server. The NetBackup Agent Request Service (NBARS) polls the primary server every 5 minutes for any non-expired data.
By default, this service reports to the primary server when it finds SAP HANA instances. However, the user can turn off discovery for a specific client, with the bpsetconfig utility. See the REPORT_CLIENT_DISCOVERIES option in the NetBackup Administrator's Guide, Volume I.
A message Starting the discovery of databases... displays after you click . This message only indicates that a request was made to start the discovery process. However, database discovery can fail for different reasons. For example, if the instance is not associated with valid credentials or the host cannot be reached. You can consider the deep discovery is successful when the message displays: Successfully started the discovery of databases. Click Refresh to update the list.
