Ubuntu Linux for IBM z Systems and LinuxONE in LPAR Installation

This document describes step-by-step the installation of Ubuntu Linux on IBM z Systems or LinuxONE in a logcal partition (LPAR).

1. Load the installation system into your LPAR

1.1 Connect to the HMC, select your LPAR and choose "Recovery", then "Load from Removable Media or Server":

Enter the parameters 'Host computer', 'User ID', 'Password' and the file location on the FTP server. In case an anonymous FTP is used, use 'anonymous' as 'User ID' and any character or string (like 'me' or suchlike) as 'Password'. The file location that points to the required installation files, like kernel.ubuntu, initrd.ubuntu and Ubuntu.ins. The path is to long to fit into the window, it is: "ubuntu-ports/dists/xenial/main/installer-s390x/current/images/generic"

Click 'Ok' to proceed.

Select an appropriate version (in case multiple versions are displayed) and click 'OK'.

Confirm with 'Yes' that you understand that the task "Load from Removable Media or Server" will cancel other job.

Acknowledge again with 'Yes' to proceed with the IPL (Initial Program Load).

2. Connect to the HMC's Operating System Messages Console:

3. Interactively answer questions related to Network, DASD, etc.

This is an example on how to enter the data. Obtain your network configuration data prior to the installation.

Configure the network device - - - - - - - - - - - - - - -
Please choose the type of your primary network interface that you will need for installing the Debian system (via NFS or HTTP). Only the listed devices are supported.
Network device type:

• 1: ctc: Channel to Channel (CTC) or ESCON connection,

  2: qeth: OSA-Express in QDIO mode / HiperSockets, 3: iucv: Inter-User Communication Vehicle - available for VM guests only, 4: virtio: KVM VirtIO,

Prompt: '?' for help>
The following picture is an example on how all further parameters have to be entered:

2
(means: Enter '2' and click the 'Send' button)

Please select the OSA-Express QDIO / HiperSockets device. Device:

• 1: 0.0.f500-0.0.f501-0.0.f502 [*],

Prompt: '?' for help, default=1> 1
By default OSA-Express cards use layer3 mode. In that mode LLC headers are removed from incoming IPv4 packets. Using the card in layer2 mode will make it keep the MAC addresses of IPv4 packets. Use this device in layer2 mode?

• 1: Yes [*] 2: No

Prompt: '?' for help, default=1> 1

Configure a network using static addressing - - - - - - - - - - - - - - - - - - - - - -

The IP address is unique to your computer and may be:

• four numbers separated by periods (IPv4);
• blocks of hexadecimal characters separated by colons (IPv6).

You can also optionally append a CIDR netmask (such as "/24").

If you don't know what to use here, consult your network administrator. IP address: Prompt: '?' for help> 9.152.162.55/22

The gateway is an IP address (four numbers separated by periods) that indicates the gateway router, also known as the default router. All traffic that goes outside your LAN (for instance, to the Internet) is sent through this router. In rare circumstances, you may have no router; in that case, you can leave this blank. If you don't know the proper answer to this question, consult your network administrator. Gateway: Prompt: '?' for help, default=9.152.160.1> 9.152.160.1

The name servers are used to look up host names on the network. Please enter the IP addresses (not host names) of up to 3 name servers, separated by spaces. Do not use commas. The first name server in the list will be the first to be queried. If you don't want to use any name server, just leave this field blank. Name server addresses: Prompt: '?' for help, default=9.152.160.1> 9.152.120.241 Detecting link on enccw0.0.f500; please wait...

Please enter the hostname for this system. The hostname is a single word that identifies your system to the network. If you don't know what your hostname should be, consult your network administrator. If you are setting up your own home network, you can make something up here. Hostname: Prompt: '?' for help, default=s83lp55> s83lp55

The domain name is the part of your Internet address to the right of your host name. It is often something that ends in .com, .net, .edu, or .org. If you are setting up a home network, you can make something up, but make sure you use the same domain name on all your computers. Domain name: Prompt: '?' for help, default=boeblingen.de.ibm.com> yourdomain.com
