Task KVC0I079—Rebuild the CP Nucleus

When applying z/VM maintenance, you must perform the following activities:

• Regenerate the CP nucleus with the CA Top Secret CP modules
• Point to the current CP IBM maintenance mini disk

Use this task to rebuild your current CP nucleus with CA Top Secret CP modules.

Rebuilding the CP nucleus consists of the following panels:

• KVC0‑I079
• KVC0-I085

Important! To build the required CA Top Secret modules into the CP nucleus, the most current version of these modules must be accessible to the z/VM service EXECs and the current IBM z/VM maintenance disks during the build. If you applied IBM z/VM CP maintenance, you must rebuild the CP nucleus with the CA Top Secret modules.

The CP nucleus module generation resembles the standard IBM VMFBLD process but includes a CAXABLD prefix that precedes the VMFBLD EXEC.

To rebuild your current CP nucleus with CA Top Secret CP modules:

1. Create a copy of the CP nucleus on the CP parameter disk (for system recovery if a problem occurs with the new CP nucleus).
2. From the Task Selection Menu, select task ID KVC0‑I079.

   You are transferred to the appropriate panel, based on your operating system selection.

3. Log on to your CP system maintenance machine.

   You can disconnect from your current terminal to perform the logon (if you do not have access to more than one terminal) or use another terminal.

4. Perform any IBM required steps prior to VMFBLD.

   Examples of what might be needed are VMFSETUP and VMFPF EXECs.

5. Perform one of the following steps (depending on whether you are regenerating a test system or production system):
   • (TEST module generation) Link to and access CAIMAINT virtual machine’s 291 disk.
   • (PRODUCTION module generation) Link to and access CAIMAINT virtual machine’s 391 and 322 disks.
6. Generate the CP nucleus module, using the supplied CAXABLD EXEC to prefix the standard VMFBLD EXEC.

   By default, the CP modules are placed on the 493 disk and must be moved to the CP parameter disk CF1. Both 493 and CF1 are defaults only and may be redefined by your system.

7. Save the CP LOAD map and the CAXALOAD SUMMARY A1. CA Support might need this information to debug problems.
