When you determine that you have an installation error, first you need to determine what your first step to recovery should be.
| Type of installation failure | |
|---|---|
| When failure occurred | What to do |
| Saving server before installation | If a problem occurs while you are saving the system, review your job log to determine what caused the failure. Correct the error and complete your system save procedure. Do not continue to replace the new release until you have a complete backup copy of your system. If you cannot complete installing the new release, you will need this backup copy to restore the system to the previous release. |
| Installing new release or licensed program | Use the next table on this page to direct you to the recovery information that you need to find the problem, determine what caused it, correct the problem, and then complete installing this release. |
| Power failure during an installation process | If you have a power failure anytime during the installation process, go to the next table on this page to determine where to start the installation again. You should be able to start with the task where you were when the failure occurred. For example, if you had completed installing the operating system when the power failed, and are now installing licensed programs, start with the task to install licensed programs. If you are using the automatic process, start at the beginning. The system can determine which tasks have not been completed and will resume at the appropriate task. |
If the installation process fails and you cannot continue the
current installation, use the book Backup and Recovery 
and your server's backup copy to restore the
previous release.
In the farthest left column of the following table, locate the installation section you were using when the failure occurred. In the second column, locate which task you were performing in that section. Locate the first task that failed during your installation and then use the information in the last column to determine your recovery starting point.
