Accommodating frequent host ID changes

Registering the host ID of the startup hard disk drive might not be possible if you have dual boot systems, if you frequently reformat your disks, or if you ghost your hard disk images.

These processes change the host ID of the startup drive. Because the products and license keys are registered to a specific host ID, you cannot use your IBM Rational® products if the host ID changes.

To avoid this situation, use one of the following methods:
  • Use floating licenses that are served by a license server with a constant host ID.
  • Use the address of the Ethernet card in the computer as a host ID.
  • Make sure that you keep the hard disk drive serial number of the startup drive constant when images are created to refresh the computer.
