Choosing the right procedure for restoring the operating system
You can restore the operating system in several different ways.
At several points during the restore process, you need to make decisions based on which of these operations you are using:
- Complete Restore
- Use a complete restore operation if the operating system is not on your system or if it has damaged objects. This restores all the IBM-supplied objects in the QSYS library and the language libraries from media.
- Abbreviated Install
- Use an abbreviated installation operation to replace parts of the operating system or system information, such as system values or the system reply list.
Use the recovery checklist that you selected in Selecting the appropriate recovery strategy topic to determine the correct procedure for your situation. You also need to know whether you are restoring from SAVSYS media or from the IBM-supplied distribution media. Use the distribution media only if you do not have usable SAVSYS media.
How to begin restoring the operating system: The steps you have already performed determine where you start:
- If you have just restored or installed the Licensed Internal Code, you are doing a complete restore operation of the i5/OS program. You should see the initial program load (IPL) or Install the System display. Start with the steps described in Tasks to restoring the operating system topic.
- If restoring the operating system is the first step or only step in your recovery process, start by performing a manual IPL.
