window to start the installation. Some software may require a license confirmation. If your software selection includes such software, license confirmation dialogs are displayed. Click Accept to install the software package. When not agreeing to the license, click I Disagree and the software package will not be installed. In the dialog that follows, confirm with Install again.
The installation usually takes between 15 and 30 minutes, depending on the system performance and the selected software scope. After having prepared the hard disk and having saved and restored the user settings, the software installation starts.
After the software installation has completed, the basic system is set up. Among others, “Finishing the Basic Installation” includes installing the boot manager, initializing fonts and more. Next YaST boots into the new Linux system to start the system configuration.
TIP: Existing SSH Host Keys
If you install SUSE Linux Enterprise Server on a machine with existing Linux installations, the installation routine automatically imports the SSH host key with the most recent access time from an existing installation.
6.15.1 IBM System z: IPLing the Installed
System
In most cases, YaST automatically reboots into the installed system on the IBM System z platform. Known exceptions to this are installations wherein the boot loader resides on an FCP device in environments with LPAR on a machine older than z9 or with z/ VM older than release 5.3. The boot loader gets written to the device that holds the /
boot directory. If /boot is not on a separate partition, it is on the same partition as the root file system /.
In cases where an automatic reboot is not possible, YaST will show a dialog box containing information about from which device to do an IPL. Accept the shutdown option and perform an IPL after the shutdown. The procedure varies according to the type of installation:
LPAR Installation
In the IBM System z HMC, select Load, select Clear, then enter the loading address (the device address of the device holding the /boot directory with the boot loader). If using a ZFCP disk as the boot device, choose Load from SCSI and specify the load address of your FCP adapter as well as WWPN and LUN of the boot device. Now start the loading process.
z/VM Installation
Log in to the VM guest (see Example 4.5, “Configuration of a z/VM
Directory” (page 55) for the configuration) as LINUX1 and proceed to IPL the installed system:
IPL 151 CLEAR
151 is an example address of the DASD boot device, replace this value with the correct address.
If using a ZFCP disk as the boot device, specify both the ZFCP WWPN and LUN of the boot device before initiating the IPL. The parameter length is limited to eight characters. Longer numbers must be separated by spaces:
SET LOADDEV PORT 50050763 00C590A9 LUN 50010000 00000000
Finally, initiate the IPL:
IPL FC00
FC00 is an example address of the ZFCP adapter, replace this value with the correct address.
6.15.2 IBM System z: Connecting to the
Installed System
After IPLing the installed system, establish a connection with it to complete the installation. The steps involved in this vary depending on the type of connection used at the outset.
Installation with YaST 121
6.15.2.1 Using VNC to Connect
A message in the 3270 terminal asks you to connect to the Linux system using a VNC client. This message is easily missed, however, because it is mixed with kernel messages and the terminal process might quit before you become aware of the message. If nothing happens for five minutes, try to initiate a connection to the Linux system using a VNC viewer.
If you connect using a Java-capable browser, enter the complete URL, consisting of the IP address of the installed system along with the port number, in the following fashion:
http://<IP of installed system>:5801/
6.15.2.2 Using X to Connect
When IPLing the installed system, make sure that the X server used for the first phase of the installation is up and still available before booting from the DASD. YaST opens on this X server to finish the installation. Complications may arise if the system is booted up but unable to connect to the X server in a timely fashion.
6.15.2.3 Using SSH to Connect
IMPORTANT: IBM System z: Connecting from a Linux or UNIX System
Start SSH in an xterm. Other terminal emulators lack complete support for the text-based interface of YaST.
A message in the 3270 terminal asks you to connect to the Linux system with an SSH client. This message is easily missed, however, because it is mixed with kernel messages and the terminal process might quit before you become aware of the message.
Once the message appears, use SSH to log in to the Linux system as root. If the connection is denied or times out, wait for the login timeout to expire, then try again (this time may vary depending on server settings).
When the connection is established, execute the command /usr/lib/YaST2/ startup/YaST2.ssh. Just executing the command yast does not suffice in this case.
YaST then begins completing the installation of the remaining packages and creating an initial system configuration.
