Chapter 17. Connecting to the installation system
After the Initial Program Load (IPL) of the Anaconda installation program is complete, connect to the IBM Z system from a local machine, as an 'install' user, using an ssh connection.
You need to connect to the installation system to continue the installation process. Use a VNC mode to run a GUI-based installation or use the established connection to run a text mode installation.

For more information about installing VNC and various VNC modes for GUI-based installation, see Chapter 25, Using VNC
17.1. Setting up remote connection using VNC
From a local machine, run the steps below to set up a remote connection with the IBM Z system.
Prequisite:
- The initial program boot is complete on the IBM Z system, and the command prompt displays:
Starting installer, one moment... Please ssh install@my-z-system (system ip address) to begin the install. - If you want to restrict VNC access to the installation system, then ensure
inst.vncpassword=PASSWORDboot parameter is configured.
- On the command prompt, run the following command:
$
ssh install@my-z-system-domain-nameOR$
ssh install@my-z-system-IP-address - Depending on whether or not have you configured the
inst.vncparameter, the ssh session displays the following output:Wheninst.vncparameter is configured:Starting installer, one moment... Please manually connect your vnc client to my-z-system:1 (system-ip-address:1) to begin the install.
Wheninst.vncparameter is not configured:Starting installer, one moment... Graphical installation is not available. Starting text mode. ============= Text mode provides a limited set of installation options. It does not offer custom partitioning for full control over the disk layout. Would you like to use VNC mode instead? 1) Start VNC 2) Use text mode Please make your choice from above ['q' to quit | 'c' to continue | 'r' to refresh]:
If you have configured theinst.vncparameter, proceed to step 5. - Enter 1 to start VNC.
- Enter a password, if you have not set the
inst.vncpassword=boot option, but want to secure the server connection. - From a new command prompt, connect to the VNC server.
$
vncviewer my-z-system-ip-address:display_numberIf you have secured the connection, use the password that you have entered in the previous step or the one that you had set forinst.vncpassword=boot option.The RHEL installer is launched in the VNC client.
