Loading and Unloading software into the coprocessor

Edit online

After installing the IBM Common Cryptographic Architecture (CCA) Support Program on the host computer, use the Coprocessor Load Utility (CLU) to load the coprocessor operating system and CCA application into the coprocessor.

If you obtain updates to the Support Program, use the CLU to reload the necessary program segments. You can also load vendor software by using the CLU.

This section includes:
  • Instructions for using the CLU to understand which coprocessors are installed and their status, and to install and uninstall the software that runs within the coprocessor
  • A reference section that describes:
    • The coprocessor memory segments
    • Validation of the coprocessor status
    • The syntax used to start the CLU utility
    • CLU return codes
Notes:
  1. The file locations referred to in this section are the default directory paths.
  2. The error codes returned by the coprocessor device driver are presented in the form of a hexadecimal number, such as X'8040xxxx'. You might encounter the errors, especially when you first use the CLU utility and are less familiar with the product and its procedures.
  3. The coprocessor function-control vector (FCV) is loaded by the CCA Node Management (CNM) utility.
