Recovering your system
This topic provides general information about backup and recovery options for the System i® environment. It describes the options available on the system, compares and contrasts them, and tells where to find more information about them. You can order a printed version of the Recovering your system PDF (SC41-5304; feature code 8007) with i5/OS software upgrade orders or new hardware orders.
This topic covers the following information:
- Procedures on how to save your system using the GO SAVE commands.
- Restoring to a different release of System i.
- Selecting the right recovery strategy.
- Procedures for restoring information to your system.
- Device parity protection procedures.
- Mirrored protection procedures.
- What's new for IBM i 7.1
Read about new or significantly changed information for the Recovering your system topic collection. - PDF file for Recovering your system
You can view and print a PDF file of this information. - Saving the system
If this is your first experience with your System i model, use the instructions in this topic collection to save all of the information about your system. Do this with the GO SAVE menu options. - Restoring the system: Introduction
This topic collection provides information about the menu options and commands that are available for restoring information and what restore commands can be used in different file systems. - Selecting the appropriate recovery strategy
Use this information to determine the correct procedure for recovering your system. - Recovering the Licensed Internal Code
Licensed Internal Code is the layer of System i architecture just above the hardware. - Restoring the operating system
Use this information to recover the operating system. - Starting the system after it ends abnormally
Use this information to start the system after it ends abnormally. - Recovering information in a user auxiliary storage pool
When you have user auxiliary storage pools (ASPs) on your system, you assign specific libraries or objects to certain physical disk devices. One reason for having user ASPs is to limit the amount of information you need to recover if a disk device must be replaced. - The restore menu
The restore menu provides many options for recovering information. - Restoring specific types of information
This topic describes procedures for restoring particular types of information on the system. It also describes considerations when you restore particular types of information, whether you restore the information by using menu options or commands. The topics are presented in the same order as the recovery operations should occur. - Restoring changed objects and apply journaled changes
The procedures in this topic are designed to recover activity that has occurred since the last complete save operation. - Mirrored protection recovery actions
On a system with mirrored protection, errors and failures have different effects. When a failure occurs on a system with mirrored protection, the recovery procedure is affected by the level of protection that is configured. - Restoring your system using Operational Assistant tapes
According to the different situations, perform one of these three tasks to restore information from Operational Assistant backup tapes. - Restoring the system from the save storage media
When you recover your system from the Save Storage (SAVSTG) media in a disaster recovery situation, you reset your system to the point when the SAVSTG procedure was run. Your system will not be available for use until the restore process completes successfully. - Restoring encrypted backups and encrypted auxiliary storage pools
You can either encrypt backup data to a tape, or encrypt data stored in user auxiliary storage pools (ASPs) and independent ASPs. If you lose the data on your system, you need to be able to restore the encrypted data. - Release-to-release support
The release-to-release support on the System i environments allows you to move data from the current release to a previous-release system. This support also allows you to move data from a previous-release system to a current-release system. - System synchronization: Planning and procedures
System synchronization is the second part of moving data between two systems. - Tips for merging two systems into a single system
Merging systems is a complex process. Various factors can affect merging systems that include the software release, system names, or IBM-supplied objects. - Using an alternate installation device
You can learn how to set up, disable, verify, and select an alternate installation device. - Configuring disks and disk protection
This topic describes the procedures for using the character-based interface to configure and protect disks on your system. - Working with auxiliary storage pools
You can use system service tools (SST) and dedicated service tools (DST) to work with auxiliary storage pools (ASPs). ASPs are also called disk pools. You can create new encrypted or unencrypted user ASPs, or add disk units to an existing ASP. - Working with device parity protection
You can use system service tools (SST) and dedicated service tools (DST) to work with device parity protection on your system. - Working with mirrored protection
This topic describes how to start and stop mirrored protection and the rules that apply when you set up a mirrored auxiliary storage pool (ASP). - Working with disk compression
This topic describes how to start and stop disk compression. It also discusses various considerations for using disk compression. - Managing auxiliary storage pools
You can use system service tools (SST) and dedicated service tools (DST) or System i Navigator to manage auxiliary storage pools (ASPs). - Examples: Techniques and programming for backup and recovery
You can use several techniques to assist with and manage your backup and recovery processes. - Licensed Internal Code installation error displays
Use the Licensed Internal Code installation error displays to determine what actions to take. For example, the system might be missing the load-source disk. - Example: Disaster recovery plan
The objective of a disaster recovery plan is to ensure that you can respond to a disaster or other emergency that affects information systems and minimize the effect on the operation of the business. When you have prepared the information described in this topic collection, store your document in a safe, accessible location off site. - Recovering your system
This topic provides instructions to completely recover your entire system. - Recovering your system to a different system
Use this information if you need to recover your system to a different system (for example, a system with a different serial number).
