Configuring secure communication between the Red Hat Virtualization server and NetBackup host
NetBackup can now validate Red Hat Virtualization server certificates using their root or intermediate certificate authority (CA) certificates.
For NetBackup 8.2, only PEM certificate format is supported for virtualization servers.
For more information, See VIRTUALIZATION_HOSTS_SECURE_CONNECT_ENABLED for servers and clients.
The following procedure is applicable for the NetBackup master server and all RHV access hosts.
To configure secure communication between Red Hat Virtualization server and RHV access host
- Configure a external certificate authority trust store on the RHV access host.
- Add CA certificates of the required Red Hat Virtualization server in the trust store on the access host.
In case of Windows certificate store, add the CA certificate to the Windows Trusted Root Certification Authorities.
Use the following command:
certutil.exe -addstore -f "Root" certificate filename
- Use the nbsetconfig command to configure the following NetBackup configuration options on the access host:
For more information on the configuration options, refer to the NetBackup Administrator's Guide.
ECA_TRUST_STORE_PATH
Specifies the file path to the certificate bundle file that contains all trusted root CA certificates.
This option is specific to file-based certificates. You should not configure this option if Windows certificate store is used.
If you have already configured this external CA option, append the RHV CA certificates to the existing external certificate trust store.
If you have not configured the option, add all the required Red Hat Virtualization server CA certificates to the trust store and set the option.
ECA_CRL_PATH
Specifies the path to the directory where the certificate revocation lists (CRL) of the external CA are located.
If you have already configured this external CA option, append the Red Hat Virtualization server CRLs to the CRL cache.
If you have not configured the option, add all the required CRLs to the CRL cache and then set the option.
VIRTUALIZATION_HOSTS_SECURE_CONNECT_ENABLED
This option affects Nutanix AHV, RHV, and VMware secure communication. Without this option, the secure or insurce communication with workload is decided by each workload and plug-in separately.
For mor information, refer to the respective workload Administrator's Guide.
For RHV, secure communication is enabled by default.
This option lets you skip the security certificate validation.
See VIRTUALIZATION_HOSTS_SECURE_CONNECT_ENABLED for servers and clients.
VIRTUALIZATION_CRL_CHECK
Lets you validate the revocation status of the virtualization server certificate against the CRLs.
By default, the option is disabled.
See VIRTUALIZATION_CRL_CHECK for NetBackup servers and clients.
For more information on external CA support, refer to the NetBackup Security and Encryption Guide.
