Changing the Spectrum Connect communication port

The TCP port used by Spectrum Connect to communicate with vCenter and vRO servers can be changed at any time.

By default, Spectrum Connect uses TCP ports 8443 or 8440 for communication with vCenter and vRO servers to access vWC, register as VASA storage provider and run orchestration workflows. The 8443 port is used if the currentSpectrum Connect has been upgraded from a previous version. The 8440 port is used if the software package has been installed anew.

To change the current Spectrum Connect communication port:

  1. Verify that you have root access privileges.
  2. Access the /opt/ibm/ibm_spectrum_connect/bin/ directory.
  3. Run the sc_port_change.sh -p <new_port_number> script, replacing new_port_number with the desired TCP port value.
    The script changes the port number and restarts the Nginx and Spectrum Connect services for the changes to take effect.
After running the script:
  • Re-register a previously registered Spectrum Connect as a VASA storage provider on the vCenter server.
  • If you are using vRO, re-run the configuration script to instruct Spectrum Connect to use the new port.
