ECA_CRL_PATH for NetBackup servers and clients
The ECA_CRL_PATH option specifies the path to the directory where the Certificate Revocation Lists (CRL) of the external certificate authority (ECA) are located.
These CRLs are copied to NetBackup CRL cache. Revocation status of the external certificate is validated against the CRLs from the CRL cache.
CRL in the CRL cache is periodically updated with the CRL on the location that is specified for ECA_CRL_PATH based on the ECA_CRL_PATH_SYNC_HOURS option.
If the ECA_CRL_CHECK or HADOOP_CRL_CHECK option is not set to DISABLE (or 0) and the ECA_CRL_PATH option is not specified, NetBackup downloads the CRLs from the URLs that are specified in the CRL distribution point (CDP) and uses them to verify revocation status of the peer host's certificate.
Note:
For validating the revocation status of a virtualization server certificate, the VIRTUALIZATION_CRL_CHECK option is used.
For validating the revocation status of a Hadoop server certificate, the HADOOP_CRL_CHECK option is used.
Table: ECA_CRL_PATH information
Usage | Description |
|---|---|
Where to use | On NetBackup servers or clients. If certificate validation is required for VMware, Red Hat Virtualization servers, Nutanix AHV, or Hadoop, this option must be set on the NetBackup primary server and respective access or backup hosts, irrespective of the certificate authority that NetBackup uses for host communication (NetBackup CA or external CA). If certificate validation is required for VMware, Red Hat Virtualization servers, or Hadoop, this option must be set on the NetBackup primary server and respective access or backup hosts, irrespective of the certificate authority that NetBackup uses for host communication (NetBackup CA or external CA). |
How to use | Use the nbgetconfig and the nbsetconfig commands to view, add, or change the option. For information about these commands, see the NetBackup Commands Reference Guide. Use the following format to specify a path to the CRL directory: ECA_CRL_PATH = Path to the CRL directory For example: ECA_CRL_PATH = /usr/eca/crl/eca_crl_file.crl If you use this option on a Flex Appliance application instance, the path must be |
