Performing an IPL to dedicated service tools

Use this procedure to perform an initial program load (IPL) to dedicated service tools (DST).

About this task

This procedure is applicable for the entire system, or if logical partitions are installed, for the primary partition.

To perform an IPL, complete the following steps:

Procedure

  1. Select a type B IPL in manual mode.
    Attention: For systems with logical partitions, you must power down the secondary partitions normally before you perform an IPL on the primary partition to avoid possible data loss.
  2. Perform one of the following options:
    • If there is a problem log entry after powering on the system, perform a delayed power-off. (This is the data for problem analysis.) When the system is off, press the Power button on the control panel to perform an IPL. If the delayed power-off takes longer than 40 minutes to complete, select function 03.
      Attention: Performing function 03 might damage objects, and it might also cause data loss.
    • If there is an attention light after powering on the system, use the increment (↑) or decrement (↓) button to select control panel function 03. Press Enter on the control panel to perform an IPL.
    • When the system is powered off, press the Power button on the control panel to perform an IPL.
  3. Is the operating system IBM i 7.4, or earlier?
    • Yes: The IPL or Install the System display is shown on the console. Select the Use Dedicated Service Tools option. The DST Sign On display is shown. Continue with the next step.
    • No: The message "Enter user and password to IPL or Install the System " is displayed. Continue with the next step.
  4. Sign on to DST with a valid user ID and password.
    Remember: Enter a valid user ID and get the password from the customer. If the customer changed the full DST authority, user ID, or password, ask the customer for the correct values.
    Notes:
    • If prompted to change the password, be sure to provide the new (changed) password to the customer.
    • If the sign-on attempts to DST exceed the number of allowable attempts, the service tools user ID is disabled. A user with a service tool security privilege must reset the user ID.
    • If the system is running the IBM i 7.6 operating system, or later, multi-factor authentication might be required. For more information about multi-factor authentication, see MFA overview.
  5. Is the operating system IBM i 7.4, or earlier?
    • Yes: The Use Dedicated Service Tools (DST) display is shown.
    • No: The IPL or Install the System display is shown. Select the Use Dedicated Service Tools option.
    Restriction: The system is in the limited paging environment.

    This ends the procedure.
