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.
About this task
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.
