The successful completion of nearly every step in the Recovering Your Entire System Report relies on information in the Recovering your system book. After you obtain a copy of the Recovering your system book, you can review and test the steps that are outlined in this section.
This chapter shows you how to use the steps in the Recovering Your Entire System Report to recover your entire system in the event of a total system failure. You should not base an actual recovery on the steps that are outlined in this chapter. For assistance during an actual recovery, you must use the recovery reports that are generated by your own system. Those reports contain recovery information particular to your own system. BRMS uses a pre-configured template as the basis for its recovery procedures, but also notes any steps that are uniquely yours. Such steps can include restoring from save files or from TSM servers.
It is very important that the QUSRBRM and QUSRSYS libraries be saved on a regular basis.
If you are using a 3494 tape library that is attached to a local area network (LAN), you must vary on the LAN line description. Use the WRKCFGSTS *LIN command to vary on the LAN line description. If you attach your 3494 through an RS–232 connection, you do not need to vary on the RS–232 line description.
The Recovering Your Entire System Report presents the steps in the order required for recovery. To perform a system recovery, you begin with the first step at the top of the system recovery report and follow the flow down through the report to the last step at the bottom of the report.
The information in the sections that follow show accurate reflections of the instructions that appear for each step in the actual report. As you read through the recovery steps, be sure to read the information inside the step as well as the text that may precede or follow it.
The following are a few general things to keep in mind as you review the steps:
