Changing the Spectrum Control Base communication port

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

About this task

By default, Spectrum Control Base 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 current Spectrum Control Base has been upgraded from a previous version. The 8440 port is used if the software package has been installed anew.

Procedure

To change the current Spectrum Control Base communication port:

  1. Verify that you have root access privileges.
  2. Access the /opt/ibm/ibm_spectrum_control/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 Control Base services for the changes to take effect.

What to do next

After running the script:
  • Re-register a previously registered Spectrum Control Base as a VASA storage provider on the vCenter server.
  • If you are using vRO, re-run the configuration script to instruct Spectrum Control Base to use the new port.
