About host ID-based certificates
Each host in a NetBackup domain has a unique identity, which is referred to as a host ID or a Universally Unique Identifier (UUID). The master server is the Certificate Authority (CA). It assigns host ID-based certificates to hosts and stores the host information in the nbdb database. The CA maintains a list of all of the host IDs that have certificates (or revoked certificates). The host ID is used in many certificate management operations to identify the host.
Host IDs are randomly generated by the system and are not tied to any property of the hardware.
NetBackup provides a list of host ID-based certificates that you have revoked.
See About the host ID-based certificate revocation list.
See Overview of security certificates in NetBackup.
Only a NetBackup administrator can control the settings that are related to certificate deployment and revocation.
The host ID remains the same even when the host name changes.
If a host obtains certificates from multiple NetBackup domains, it has multiple host IDs that correspond to each NetBackup domain.
When the master server is configured as part of a cluster, each node in the cluster receives a unique host ID. An additional host ID is assigned for the virtual name. For example, if the master server cluster is comprised of N nodes, the number of host IDs that are allocated for the master server cluster is N + 1.
