About the NetBackup answer file
The NetBackup answer file (/tmp/NBInstallAnswer.conf) is used during UNIX and Linux installs and upgrades to:
Override some default values.
Avoid answering some questions during interactive installation.
Perform unattended or silent UNIX and Linux client installs and upgrades on most supported operating systems.
Templates for media and clients are available at the top level of the NetBackup installation image downloaded from Veritas.
Populate the NetBackup answer file on the target host before you run the installation script. Create the file if it does not exist. The supported entries are shown along with any relevant information.

If this operation is an initial installation or an upgrade from pre-8.0, at least one set of security configuration parameters must be provided.
To use the NetBackup master server as your Certificate Authority, the CA_CERTIFICATE_FINGERPRINT of the master server must be provided. The AUTHORIZATION_TOKEN option may be required depending on either the security level of the master server or if this computer is already configured on the master server. More information is available: https://www.veritas.com/support/en_US/article.000127129.
To use an external certificate authority, the ECA_CERT_PATH, ECA_CRL_CHECK_LEVEL, ECA_PRIVATE_KEY_PATH, and ECA_TRUST_STORE_PATH values are required. The ECA_CRL_PATH and ECA_KEY_PASSPHRASEFILE values are optional. More information is available: https://www.veritas.com/support/en_US/article.100044300.
To continue the installation or upgrade without configuring the certificate authority, specify SKIP for all the required ECA_ options. Be aware the installation or upgrade fails if you don't set all the ECA_ values to SKIP. If you continue the installation or the upgrade without the required certificate authority components, backups and restores fail.
Description: Use this option to identify how a NAT client connects with a NetBackup host. Accepted values are TRUE and FALSE. Set this option to TRUE if NetBackup needs to support NAT, otherwise set it to FALSE. Set ACCEPT_REVERSE_CONNECTION = FALSE if:
You do not want NetBackup to support NAT clients.
The NetBackup clients are not behind the firewall.
Default value: FALSE
ACCEPT_REVERSE_CONNECTION=TRUE | FALSE
Description: This option specifies that NetBackup should automatically use an authorization or a reissue token when it retrieves the host certificate. The AUTHORIZATION_TOKEN is 16 upper case letters. Some environments require an authorization token for backups and restores to work correctly. If this information is required and is not provided in the answer file, the installation fails. If SKIP is specified, the installer attempts to retrieve a host certificate without including a token. In some environments this choice may result in additional manual steps following the installation.
Be aware that AUTHORIZATION_TOKEN is ignored on upgrade under either of these conditions:
NBCA is already configured on the host.
ECA is in use on the master server.
Default value: None.
Required: Review About security configuration considerations for details.
AUTHORIZATION_TOKEN=ABCDEFGHIJKLMNOP | SKIP
Description: This option specifies the Certificate Authority (CA) Certificate Fingerprint. The Certificate Fingerprint is retrieved from the CA during installation or upgrade. The fingerprint format is 59 characters and is a combination of the digits 0-9, the letters A-F, and colons. For example, 01:23:45:67:89:AB:CD:EF:01:23:45:67:89:AB:CD:EF:01:23:45:67. The fingerprint value must match the fingerprint for the server value that is specified in the first SERVER=server_name option. To continue the installation or upgrade without configuring security, specify CA_CERTIFICATE_FINGERPRINT=SKIP.
Be aware that CA_CERTIFICATE_FINGERPRINT is ignored on upgrade under either of these conditions:
NBCA is already configured on the host.
ECA is in use on the master server.
Default value: None.
Required: Review About security configuration considerations for details.
CA_CERTIFICATE_FINGERPRINT=fingerprint | SKIP
Description: This option specifies the name that NetBackup uses to identify this computer. The XLOCALHOSTX value lets the local host provide the computer name. If this value is used, it may be possible to use the same answer file on all computers within a single master server domain. This value is added to the
bp.conffile.If CLIENT_NAME is specified on upgrade, a check is made to validate that the name that is provided in the answer file matches the value that is configured in the
bp.conffile.Default value: None.
Required: Yes
CLIENT_NAME=name | XLOCALHOSTX
Description: This option specifies the path and the file name of the external certificate file.
To skip setting up the certificate authority, set all required ECA_ values to SKIP. Be aware that if you continue with the installation without a certificate authority, the backups and restores fail.
The ECA_CERT_PATH option is ignored on upgrade if ECA is already configured on the host or if NBCA only is in use on the master server.
Default value: None.
Required: Review About security configuration considerations for details.
ECA_CERT_PATH=path_and_file_name
Description: This option specifies the CRL mode. Supported values are:
USE_CDP: Use the CRL defined in the certificate.
USE_PATH: Use the CRL at the path that is specified in ECA_CRL_PATH.
