Installing a CA-signed server certificate for the cluster

To enable an SSL server to authenticate the cluster or storage virtual machine (SVM) as an SSL client, you install a digital certificate with the client type on the cluster or SVM. Then you provide the client-ca certificate to the SSL server administrator for installation on the server.

  1. To use a CA-signed digital certificate for client authentication, complete the following steps:
    1. Generate a digital certificate signing request (CSR) by using the security certificate generate-csr command.

      Result

      ONTAP displays the CSR output, which includes a certificate request and private key, and reminds you to copy the output to a file for future reference.

    2. Send the certificate request from the CSR output in an electronic form (such as email) to a trusted CA for signing.

      You should keep a copy of the private key and the CA-signed certificate for future reference.

      Result

      After processing your request, the CA sends you the signed digital certificate.

    3. Install the CA-signed certificate by using the security certificate install command with the -type client parameter.
    4. Enter the certificate and the private key when you are prompted, and then press Enter .
    5. Enter any additional root or intermediate certificates when you are prompted, and then press Enter.

      You install an intermediate certificate on the cluster or SVM if a certificate chain that begins at the trusted root CA, and ends with the SSL certificate issued to you, is missing the intermediate certificates. An intermediate certificate is a subordinate certificate issued by the trusted root specifically to issue end-entity server certificates. The result is a certificate chain that begins at the trusted root CA, goes through the intermediate certificate, and ends with the SSL certificate issued to you.

  2. Provide the client-ca certificate of the cluster or SVM to the administrator of the SSL server for installation on the server.

    The security certificate show command with the -instance and -type client-ca parameters displays the client-ca certificate information.
