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.

The host names or IP addresses that NetBackup detects are automatically mapped to the respective host ID, if the Automatically map host names to their NetBackup host ID option is selected in Settings > Global security > Secure communication.

See Automatically mapping host ID to host names and IP addresses.

Important notes

Review the following notes specific to host ID to host name mappings:

  • In the case of DHCP (Dynamic Host Configuration Protocol) hosts, NetBackup may detect dynamic IP addresses 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.

  • You may choose to redeploy a certificate on a host using a host name that is not mapped with the existing host ID. In this case a new certificate is deployed and a new host ID is issued to the host. This action occurs 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 you register NetBackup Snapshot Manager to NetBackup, the 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.

To add host ID to host name mappings

  1. On the left, select Security > Host mappings.
  2. On the Hosts tab, locate the host that you want to modify.
  3. Select Actions > Manage mappings.

    The host ID of the client host is displayed along with the existing mappings.

  4. Select Add.
  5. Provide the following details:

    Mapping name

    Specify the host ID-to-host name mapping.

    Note:

    The host ID-to-host name mappings are not case-sensitive.

    Audit reason

    For auditing purposes, specify the reason or additional information for why you want to add this mapping.

To add a host ID to host name mapping using the command-line interface

  1. Run the following command to authenticate your web services logon:

    bpnbat -login -loginType WEB

  2. Run the following command to add a host ID to host name mapping:

    nbhostmgmt -add -hostid host_ID -mappingname mapping_name
