    Import QW Client Certificate
    You can browse to select and import the specified certificate files for:
    • QW Client CA trust chain

    • QW Client Certificate

    • QW Server root CA: Navigate to Import QW Server Certificate panel and import a QW Server root CA certificate for the storage system.

    The import file must be in pem format.
  4. When you have completed your choices, click Import to accept your choices and close the dialog; otherwise click Cancel.
  5. Along with importing the QW Client certificates on the storage system, you must import the QW Server Certificates on the QW server to establish a secure connection.

    Importing QW Server Certificate

    Generate a CSR using a CSR generation tool available in your local system for a QW server. You cannot import a QW server certificate from HPE SSMC.

    Before you import:

    • Assemble a server certificate bundle (cert.pem) for use by the local Quorum Witness server. The bundle includes QW server private key, server CA certificate, and the server CA trust chain.

    • Save the bundle file as cert.pem.

    • Import the bundle file (cert.pem) to /usr/local/etc.

    • Import the root CA cert file (cacert.pem) to /usr/local/etc. The cacert.pem includes root CA of the QW client.

    1. Generate CSR.

    2. Get a signed certificate from CA for the QW server.

    3. Import the cert.pem, cacert.pem, and QW client root CA to /usr/local/etc directory on the QW server. The import file must be in pem format.

      To start running QW on the server and HPE Storage System after installing the certificates, run the following commands on the QW server:
      $systemctl stop qwserv
      $systemctl start qwserv
      $systemctl status qwserv 
      Appearance of an error message indicates that the command was unsuccessful.
