Disk configuration warning and error messages

You see a disk configuration warning or an error report on a display when your system detects errors or warning conditions in your disk configuration. You might see this display immediately after the hardware upgrade procedure or while you are installing the IBM® i operating system.

Perform the actions necessary if you see a disk configuration warning or an error report. The action you take for each message depends on the upgrade method that you are using. The following table lists the messages that you might see on the display and the actions that you should take. For each message, you can select option 5 (Display Detailed Report) to see more information about why the message occurred and what possible actions are available.

Attention: Are you using Option 1? When you are installing the Licensed Internal Code by using option 1 from the Install the Licensed Internal Code (LIC) menu, disk configuration warning messages might mean that the system will not be able to recover its ability to access the data on your disk units. Important: Do not ignore these messages or attempt to resolve them without consulting the table. An incorrect response will probably require you to reload your data.
