Last Updated : Jun 06, 2026 |

About this task

This procedure is required for both preloaded/prelicensed ASP S8300 and fresh install on ASP S8300.

Before adding an Avaya Solutions Platform S8300 host, to regenerate the Avaya Solutions Platform S8300 self-signed certificate with FQDN, perform the following steps:

For information about adding an Avaya Solutions Platform S8300 host, see Adding an Avaya Solutions Platform S8300 Release host.

Procedure

  1. Log in to the Avaya Solutions Platform S8300 command line interface.
  2. To change the FQDN, type the following command:

    esxcli system hostname set --fqdn=server.abc.com

    Here, server.abc.com is the FQDN of the ESXi host.

    For more information, see Changing the host name on the VMware documentation website.

  3. To regenerate the self-signed certificate, do the following:
    1. Enable SSH on the ESXi host, then put the ESXi host into the maintenance mode.
    2. SSH to the ESXi host and use the following commands to take backups of the current certificate file and private key file.

      cd /etc/vmware/ssl

      mv rui.crt rui.crt.bkp

      mv rui.key rui.key.bkp

    3. To regenerate a new certificate, type the following command:

      /sbin/generate-certificates

      Verify that the new certificate file and private key file are generated.

    4. To restart the ESXi Server management agent, reboot the host.

      The ESXi host generates a new self-signed certificate.
