Examples: console service functions (65+21)

The following information describes how the console service functions (65+21) work using the control panel. The same process applies if you are using a Hardware Management Console (HMC).

The following is an example of how the console service functions work:
  1. If your system is not in manual mode or the extended functions are not activated, then complete the following steps:
    • HMC: Place the server in manual mode using the control panel.
    • Control panel:
      1. Place the server in manual mode using the control panel.
      2. Using the Up and Down buttons, select function 25. Press Enter.
      3. Use the Up button to select function 26. Press Enter.
  2. Using the control panel, enter function 65. You might see the status of a serial connection change to Connecting console. (Function 65 deactivates the communications adapter used by the local console that is directly attached.)
  3. Enter function 21 within approximately 45 seconds. Function 21 must be entered within 45 seconds for the system to pair the two functions together.

    If you enter the functions 21s after 45 seconds, the system forces DST to the console. Depending on the state of the server, you might or might not see a change at the console.

  4. The control panel responds with system reference code (SRC) A6nn500A.
  5. Enter functions 65 and 21 again to put the system in edit mode. When the system is in edit mode, you can change or perform an action. The control panel responds with SRC A6nn500B to indicate that you are in edit mode.

    To cancel out of edit mode, enter function 66. This function does not have to complete successfully.

  6. Enter functions 65 and 21 repeatedly until you reach the action that you intend to perform. Within edit mode, each repetition of functions 65 and 21 increment nn of the SRC.
  7. When you reach the value for the action you want to perform, enter function 21 to perform the action. The SRC displays A6nn500C to indicate that the action was successfully submitted.

For more information about A6nn500x SRCs, see Table 1 and Table 2.

Example 1: Changing the console type

To change the console type from a twinaxial console to a local console on a network (LAN), complete the following tasks using the console service functions on the control panel:
  1. Enter function 65.
  2. Enter function 21 within 45 seconds of entering function 65. The control panel displays SRC A601500A, indicating that the current console value is twinaxial console.
  3. Enter function 65.
  4. Enter function 21. The control panel displays SRC A602500B, indicating that you are now in edit mode and the console value is Operations Console (LAN).
  5. Enter function 65.
  6. Enter function 21. The control panel displays SRC A603500B, indicating that you are still in edit mode and the console value is Operations Console (LAN).
  7. Enter function 21 to submit the action. The control panel displays SRC A603500C, indicating that the console value change to Operations Console (LAN) was successfully submitted.

Example 2: Resetting the console without changing the console mode

This example explains how to reset the hardware associated with the configured console connection.

Important: If you already have a working console and you use this example, the console will temporarily disconnect from the server during this reset process but will automatically reconnect to the server. Also, this example does not correct all errors associated with a console failure.
To reset the console without changing the console value, complete the following tasks using the console service functions (65+21) on the control panel:
  1. Enter function 65.
  2. Enter function 21 within 45 seconds of entering function 65. The control panel displays A6nn500A indicating the current console value.
  3. Enter function 21. The control panel displays A6nn500C, indicating that the console value change to the current console value was successfully submitted.

Exception 1: Reactivating the LAN adapter

If you change the console type to Operations Console (LAN), you might have to reactivate the LAN adapter using function A3.

Exception 2: Reconnecting the 5250 emulator

If you are using a local console on a network (LAN), the emulator might become disconnected and display Disconnected.

Example: The current console type is a local console that is directly attached and you already have a service host name for other tools so the LAN adapter is currently active. However, you need to change the console type to a local console on a network (LAN) using the console service functions (65+21). The local console on a network (LAN) has data (Console Information Status window) and is connected, but it is not the current console. Using the console service functions (65+21) to set the console type to a local console on a network (LAN) disconnects the emulator on the local console on a network (LAN). To reconnect the emulator, click Communication, and then select Connect. The emulator might become the current console depending on other factors.
