Replacing the Operating System

__ 1. The IPL or Install the System menu appears on your console.

Load the first volume of installation media that contains OS/400. (This volume is labeled B29xx_01, where 29xx is the identifier for the primary language.) When you are installing from optical media, wait until the In Use indicator goes out before you continue. Then do the following to respond to the display:

IPL or Install the System

System: XXXX Select one of the following:

1. Perform an IPL

2. Install the operating system 3. Use Dedicated Service Tools (DST)

4. Perform automatic installation of the operating system 5. Save Licensed Internal Code

If you want to start Redundant Array of Independent Disks (RAID) or want to add new disk units to your RAID configuration, refer to the book Backup and Recovery, SC41-5304-05 for information about the proper sequence for configuring disk protection. Then return to this step.

After you install the new release over your previous release (V4R4M0 or V4R5M0), passwords for all service tools user profiles that still use the default password expire automatically. When you try to log on or access service tools using those profiles, you receive a message that the password has expired and must be changed. Follow the prompts or press the

appropriate key (F9) to change the password for that user profile. For more information on service tools user profiles, see Tips and Tools for Securing Your iSeries, SC41-5300-07.

Type2 (Install the operating system) and press Enter.

__ 2. The Confirm Install of OS/400 display is shown on your console. Press Enter.

__ 3. Adding Disk Units Subtask

a. If the Add All Disk Units to the System menu does not appear, go to step 4 on page 34. If the Add All Disk Units to the System menu appears, it could look like the following example.

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 disk units to the system auxiliary storage pool 4. Add all disk units to the system ASP and balance data

If you have RAID-capable disk units on your system or if your system ASP has mirrored protection, your display has two options. If you want to configure the disk units using DST now, type2 .

If you do not want device parity protection or mirrored protection or user ASPs, select option 3 (Add all disk units to the system auxiliary storage pool). By adding disk units before you install the operating system, you improve your overall system performance because the operating system is distributed across all of your disk units.

For logical partitions only

If you will be creating secondary logical partitions later, you do not want to configure all units now. Refer to the worksheet supplied by IBM for the configuration selection. To access this worksheet, refer to the Logical Partitioning Web site:

http://www.ibm.com/eserver/iseries/lpar.

Note: If either the Disk Configuration Error Report display or the Disk Configuration Warning Report display appears, go to

“Appendix F. Disk Configuration Warning and Error Messages” on page 159 to determine the appropriate action.

b. You could see the following display if your disk configuration has changed. Type 5 next to the problem and press Enter to display the detailed report.

c. If the following display appears, a disk unit that you selected to add to your disk configuration may already have data on it. If you choose to continue, any data on that is on the disk units listed will be removed.

Be certain that you want to configure the disk before you continue.

Follow the instructions on the display. Press Enter to return to the Problem Report screen. Press F10 to continue the Add Disk Unit subtask.

Possibly Configured Units Problem: These non-configured units appear to be configured units of some other disk configuration and may contain valid data. This option will clear the data from these units and destroy the other disk configuration.

Press Enter to continue

Press F12=Cancel to return and change your choices.
