Adding host ID to host name mappings
Hosts may have multiple host names or IP addresses associated with them. For successful communication between hosts, all relevant host names and IP addresses need to be mapped to the respective host IDs.
During communication, NetBackup may detect new host names or IP addresses with respect to a host ID. These host names or IP addresses can be automatically or manually mapped to the respective host ID for successful communication.
Host names or IP addresses that are detected by the system are automatically mapped to the respective host ID, if the option on the tab is selected.
See Automatically mapping host ID to host names and IP addresses.
Review the following notes specific to host ID to host name mappings:
In the case of DHCP (Dynamic Host Configuration Protocol) hosts, dynamic IP addresses may be detected by the system during communication and added as host ID to host name mappings. You should delete such mappings.
In the case of a cluster setup, host name, and FQDN (Fully Qualified Domain Name) of virtual name are discovered during host communication.
If you redeploy a certificate on a host using a host name that is not mapped with the existing host ID, a new certificate is deployed and a new host ID is issued to the host. This is because, NetBackup considers it as a different host. To avoid this situation, you should map all available host names with the existing host ID.
When registering NetBackup Snapshot Manager to NetBackup, certificates that are generated are exchanged between them. Hence the NetBackup Snapshot Manager's Host Mapping displays the details of the NetBackup Snapshot Manager container instead of the NetBackup Snapshot Manager host.
Use the following procedure to manually map a specific host ID to the corresponding host names or IP addresses.
See Add or Remove Host Mappings dialog box.
See Removing host ID to host name mappings.
