Troubleshooting software installation problems

This information describes common problem scenarios, recovery methods, and ways to get help if you encounter a problem during software installation.

Error messages and reference codes (also known as system reference codes or SRCs) let you know that an error occurred during the installation process. Use the error messages or reference codes to determine which part of the process failed.

• Where to begin recovery
  When you determine that you have an installation error, first you need to determine what your first step to recovery should be.
• Image catalog recovery
  If you used an image catalog to install, follow these procedures to determine where the failure occurred and the appropriate recovery action.
• Operations Console recovery
  Following are common problems that can occur when using Operations Console during an i5/OS™ installation or upgrade.
• Starting point for automatic installation recovery
  If you used the automatic installation process (replacing a release using automatic installation), use the following information to determine where the failure occurred and the appropriate recovery action.
• Licensed Internal Code recovery
  Use this procedure if an error occurred when you installed the Licensed Internal Code.
• Operating system recovery
  Use this procedure if an error occurred when you installed the i5/OS™ operating system.
• Licensed programs, PTFs, and secondary language recovery
  Use this procedure if an error occurred when you installed a licensed program, PTF, or secondary language.
• Starting the automatic installation process again
  Use one of three methods if you want to start the automatic installation process again after recovering from an error.
• Starting the manual installation process again
  Use one of these methods if you want to start the manual installation process again after you recover from an error while installing licensed programs, PTFs, or secondary languages.
• 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.
• Disk configuration warning and error messages
  Perform the actions necessary if you see a disk configuration warning or an error report.
• Starting from a power-off condition
  If your system unit power is off, perform the following steps to power on the system and begin a normal installation.
• Reference codes for software installation
  If a reference code appeared during the automatic or manual installation, use these procedures.
