Initialize System (INZSYS) recovery

In a software upgrade, the installation is complete when the licensed program portion of the installation process is completed and the INZSYS process successfully is completed. Use this information if the INZSYS process did not complete.

The installation process must end before the INZSYS process is automatically started. This process is initiated during each IPL after you install the QUSRSYS library until the INZSYS process has successfully completed. The INZSYS process will not be initiated during the IPL if the system is in the restricted state. If the INZSYS process is initiated during the IPL, it runs in the SCPF system job.

Note: If you perform an IPL before installing a cumulative PTF package, make sure that the INZSYS process has completed before you start to install the PTF package. Using any PTF commands before the INZSYS process is completed causes the INZSYS to fail.

The completion time for INZSYS varies. Allow sufficient time for this process to complete.

When you select option 50 (Display log for messages) on the Work with Licensed Programs menu, you should see the message Initialize System (INZSYS) started. Later, you should see the message Initialize System (INZSYS) processing completed successfully (CPC37A9). If you do not see the completed message, or if the message Initialize System (INZSYS) failed appears, look at the job log to determine the problem. Use the information in the job log to correct the problem. Then start the conversion process again.

To start the conversion process yourself, you can either use a batch job or enter INZSYS on the i5/OS™ control language (CL) command line. If you use a batch job, you can use your workstation while the process is running, but the server cannot be in a restricted state. Batch jobs do not run when the server is in a restricted state. If you enter INZSYS from a CL command line, IBM recommends that the server be in a restricted state. Setting the server to a restricted state reduces the time that is needed for the INZSYS process to complete. Before you use the INZSYS command, set the mode selection to Normal and set the IPL type to B (or the IPL type that you use for everyday operation).

To set the server to restricted state, do the following:

  1. Type CHGMSGQ QSYSOPR *BREAK SEV(60) and press Enter.
  2. A message display could be shown. Press Enter. (Ignore the messages that are shown.)
  3. Type the End Subsystem (ENDSBS) command: ENDSBS *ALL *IMMED.

    The message System ended to restricted condition appears.

    Press Enter to continue.

To start the conversion process again, do the following:

  1. Type INZSYS and press Enter.
  2. Use option 50 (Display log for messages) on the Work with Licensed Programs menu to make sure that the process is completed successfully.

Do not attempt to save your system until the INZSYS process has completed successfully.
