How can I boot the BS2000 on an SU /390?

Requirement

Logging into the SE Manager as administrator, BS2000 administrator or a privileged operator.

The Power status of the SU /390 shows the value On.

Procedure

>	Switch to the BS2000 operation mode tab of the SU/390:
>	Click Open in the SVP console group: If the browser now displays a warning about the security certificate, click Continue to this website.
	The SVP console window opens.
>	Press the Enter key. The MODE SELECTION FRAME appears. If the SVP has already been worked with, the last frame used will appear. You reach the MODE SELECTION FRAME by entering FR ML in the entry line. You can operate the SVP console in the familiar manner using the keyboard. A virtual keyboard is also available to you for making entries on the SVP console. (Click the keyboard icon at the top right to open the virtual keyboard. Clicking the icon again closes the keyboard.) Enter the alphanumeric characters shown in the frame in the input fields marked by an arrow (=>).
>	To load BS2000, enter FUNCTION ==> ld and press the Enter key. The PROGRAM LOAD FRAME: DETAIL-1 frame will appear. You can start execution of IPL with the entries in this frame. The frame shows, among other things, the (current and preset) load device (also called IPL or boot load device) of BS2000. As the Server Unit was rebooted, the IPL load device from the auto IPL configuration is set. This can differ from the IPL load device of the last IPL. If necessary, select a different load device under IPL-DEVICE. Initial startup from the IPL load device requires a DIALOG startup. LOAD FUNCTION ==> 3 must be selected for this purpose. Take note of the setting for PARMS ==>. This depends on the BS2000 operating mode set. In VM2000 mode, PARMS ==> 1 must be set. In Native BS2000 mode, a blank must be entered there.
>	In VM2000 mode, switch to the PROGRAM LOAD FRAME: DETAIL-2 if necessary using PF9 in order to check the settings for loading the VM2000 firmware. In VM2000 mode, VM MODE ==> 2 must be set there.
>	For LOAD FUNCTION ==> select one of the functions LOAD or START and press the Enter key.
>	Please monitor the further procedure on the BS2000 console. Take note of the console messages and answer the question messages. As a large number of messages are output one after the other, question messages can also quickly “disappear”. The /SHOW-PENDING-MSG (or /STATUS MSG) command enables you to have all the open question messages displayed again.

As soon as the message NSI0000 displays “System ready”, startup of BS2000 has already been largely completed. You can continue to observe the current BS2000 session on the console and, when necessary, react to system messages (e.g. reply to a mount message).

For more extensive administration tasks in BS2000, you must log in on BS2000, see section "How do I open or close a BS2000 dialog?".
