Task 1: Starting to restore the operating system

Use these procedures to prepare for restoring the operating system.

If you are using an encrypting tape drive, ensure that the Encryption Key Manager (EKM) is running and connected to the tape library before you begin the recovery operation. The EKM contains the encryption keys that are needed for the recovery operation. Skip this step if you are not using an encrypting tape drive.
Load the first media volume from your most recent SAVSYS media in the appropriate device.
- If you do not have SAVSYS media or they are unusable, load the first CD from the distribution media. Use the distribution media only if no SAVSYS media exists.
- If you are using encrypted user auxiliary storage pools (ASPs) or independent ASPs, ensure that you are using the SAVSYS media that contains the encryption keys for the ASPs.
Attention: Do not use media that you created through dedicated service tools (DST) by using option 5=Save Licensed Internal Code from the initial program load (IPL) or Install the System menu unless you have been instructed to do so by Software Services. Media created through this process does not contain the Licensed Internal Code program temporary fix (PTF) inventory information or the i5/OS operating system. If you perform the recovery process using this media, you will have to reinstall the Licensed Internal Code from either SAVSYS media or from your distribution media before you can load any PTFs onto the system.
From the IPL or Install the System display, select option 2 (Install the operating system).
Note: Do not use option 4 (Perform automatic installation of the operating system) to restore the operating system. This option can only be used for installing the system and not for system recovery.

Make a selection on the Install Device Type Selection display and press Enter.

                    Install Device Type Selection
                                                          System: XXXX
Select the installation device type 

       1.  Tape
       2.  Optical
       3.  Virtual device - preselected image catalog
       4.  Current alternate selected device

Press the Enter key.

The Confirm Install of the Operating System display will appear.

                    Confirm Install of Operating System

Press Enter to confirm your choice to install the operating 
   system. 
Press F12 to return and cancel your choice to install the
   operating system.

Press the Enter key. If you see the Dedicated Service Tools (DST) Sign On display, continue with step 7. If you see the Select a Language Group display, skip to step 8.
If your system is set up to prevent unauthorized installation of the operating system, the Dedicated Service Tools (DST) Sign On display will appear.
```
                     Dedicated Service Tools (DST) Sign On

   Type choice, press Enter.  
   Service tools user . . . . . . . . . .   ______
   Service tools password . . . . . . . .   ______ 
```
Type the DST service tools user ID and the DST service tools password and press the Enter key. You see the Select a Language Group display.

Notes:
- The DST service tools user ID and DST service tools password are case sensitive.
- Sign on to DST using a service tools user profile that has security officer authority and the assigned password. The service tools user for security level DST is QSECOFR. The service tools profile QSECOFR password is expired after the first use. At the Change Service Tools User Password display, enter in all uppercase letters the current password QSECOFR and a new password, along with the verification password.
- If your current DST password does not work, the password might have been reset to the shipped value. Try QSECOFR as the DST password.
- For more information about securing the installation of the operating system, see Restoring the operating system.

You are shown the Select a Language Group display. This display shows the primary language currently on the save media that you are restoring.

                          Select a Language Group

 Note:  The language feature shown is the language feature
 installed on the system.   

 Type choice, press Enter.
   
 Language feature . . . . . . . . . . . . . . .  2924

This value should match the value that is already on your system. If it does not, check to ensure that you have the correct save media. If you change the value on the display, you will be prompted to insert different media to load a different language feature. Press the Enter key. You are shown the Confirm Language Feature Selection display.

                     Confirm Language Feature Selection

Language feature  . . . . . . . . . . . . . . . . . :   2924

Press Enter to confirm your choice for language feature.   
   Installing the system will continue.
Press F12 to return to change your choice for 
   language feature.

Press the Enter key to confirm the information.
Note: If you have to change your system's primary language, see Changing the primary language of your system or logical partition for more information.

If you see the Add All Disk Units to the System display, continue with step 10. If you see an IPL status message display, skip to step 11.

The Add All Disk Units to the System display is shown only if disk units are in nonconfigured status.

                     Add All Disk Units to the System
                                                               System: XXXX
   Select one of the following:  
    1. Keep the current disk configuration
    2. Perform disk configuration using DST
    3. Add all units to the system auxiliary storage pool
    4. Add all units to the system ASP and balance data

Disk units might be in nonconfigured status for these reasons:

The Licensed Internal Code was installed using option 2 or option 3.
The recover disk configuration procedure was not run.
All disk units except unit 1 appear in nonconfigured status.
You have new or spare disk units that have not yet been configured on your system.

Use the information in Table 1 to determine how to respond to this display:

Table 1. Configuring disk while installing the operating system
Your recovery situation	How to respond to the display
Restoring your entire system to a different system or to an upgraded system.	If you plan to have user ASPs or mirrored protection you can select option 2 to configure your disks now. Or, you can select option 1 now and configure the disks after you have restored the operating system. Use the instructions in the Configuring disks and disk protection topic if you plan to configure disk protection or user ASPs. If you want all disks in the system ASP and do not plan to have mirrored protection, select option 3.
The Licensed Internal Code was installed on your own system using option 2 or option 3 during a recovery.	If you want all disks in the system ASP and do not plan to have mirrored protection, select option 3. If you had user ASPs or mirrored protection on your system before the failure, you can select option 2 to reconfigure your disks. This removes any data from disks that show as not configured. You can select option 1 and configure your disks later. However, the system will not be able to recover the data on the disks that are not configured.

After selecting option 3, you receive an Attention Report display. Take the directed action for more detailed information, if necessary. Otherwise, press F10 to accept the problems and continue.

If you installed the Licensed Internal Code using option 2, you receive an Attention report display. Take the directed action for more detailed information, if necessary. Otherwise, press F10 to accept the problems and continue.

Here is an example of a status display. These status displays do not require any action by the user.

Wait for next display or press F16 for DST main menu

The following list shows some of the IPL steps that are shown on the Licensed Internal Code IPL in Progress display:

Authority Recovery
Journal Recovery
Database Recovery
Journal Synchronization
Start the Operating System

Some of the IPL steps might take a long time.

While the system is performing the IPL, system reference codes (SRCs) are displayed on the control panel of the system unit or logical partition to indicate what step is in progress. The System reference code list describes these SRCs. If the same SRC is displayed for a long time in solid (not flickering) lights, your system might have a problem completing the IPL. Contact software support.

The system might prompt you for additional volumes of your SAVSYS media or the distribution media. Follow the instructions on the display.

After the IPL steps are completed, the Install the Operating System menu is displayed.
