Use the Change PowerHA Webserver (CHGHAWEB) command to specify the port numbers used for the HTTP server and the HTTPS server. The port number is ignored if a particular server is *OFF.
Procedure:
Run the CHGHAWEB command, specifying the desired port number. The following example changes the secure HTTPS server port to 12345:
CHGHAWEB HTTPS(*SAME 12345)
Note: The PowerHA HTTP server instance must be restarted after changing the port number. See Restarting the PowerHA Web Interface for additional information on restarting the PowerHA Web Interface.
Result:
After restarting the Web Interface, the server can be accessed using the new port. For example: https://<system-name>:12345.
