Configure and Customize Dell PowerFlex v3.6.x

Ensure that you have access credentials for the node on which the PowerFlex presentation server is installed.

PowerFlex presentation server configurations can be modified either by configuring a file, or by configuring operating system environment variables. If the environmental variables option is used, anything configured via the configuration file will be overridden.

The following items can be configured for the PowerFlex presentation server. The values shown for each one are the default values.

• Network
  • backend.httpd.httpsPort = 8443

    Port for the user to connect to the system using a browser

  • backend.httpd.httpRedirect = false

    If set to true, every HTTP request on the configured ports will be automatically redirected to HTTPS on the port configured with the backend.httpd.httpsPort property.

  • backend.httpd.secondaryHttpPort = 0

    The system admin can configure a secondary HTTP port that will also be redirected to the HTTPS port via the redirect property. This option allows the system admin to configure HTTP redirection with two different ports. For example, HTTP : 80 → HTTPS → 443. If the value is set to zero, the property will be ignored.
