Red Hat ENTERPRISE LINUX 3 - FOR IBM S-390 AND IBM ESERVER ZSERIES, Installation Manual

Page: 12 / 108

The network configuration must be determined beforehand. Red Hat Enterprise Linux for S/390
supports multiple network devices including CTC (channel-to-channel), IUCV (inter-user
communication vehicle), LCS (LAN channel station), and QDIO-enabled (Queued Direct I/O)
devices.
For the purposes of this installation, it is recommended that at least 4 GB of disk space (such as
two 2 GB DASD, direct access storage device, partitions or equivalent zSeries SCSI LUNs) be
allocated for the installation process. All DASD disk allocations should be completed prior to the
install process. After the installation, more DASD or SCSI (for zSeries only) disk partitions may
be added or deleted as necessary.
2. Basic Overview of the Boot Method
To prepare for installation, you must have the Linux kernel (
kernel.img
), the ram disk
(
initrd.img
), a CMS configuration file (
generic.conf
) and a parameter file. Sample
parameter and CMS configuration files are provided (
generic.prm
and
generic.conf
). You
should edit the CMS configuration file and add information about your DASD. You may also
want to add some information about your network configuration. Once this is started on the
S/390, the networking is configured. You can then use telnet or ssh on another computer to log
into your Red Hat Enterprise Linux installation image. Now you can start an installation script to
install Red Hat Enterprise Linux.
Note
The CMS configuration file is a new file for Red Hat Enterprise Linux 5.0.0. Users
of prior releases should note this addition. This new file is explained in more
detail throughout Chapter 1, Steps to Get You Started .
3. Preparing for a Network Installation
The Red Hat Enterprise Linux installation media must be available for either a network
installation (via NFS, FTP, or HTTP) or installation via local storage. Use the following steps if
you are performing an NFS, FTP, or HTTP installation.
The NFS, FTP, or HTTP server to be used for installation over the network must be a separate
machine which can provide the complete
RedHat/
directory. Both the
RedHat/base/
and
RedHat/RPMS/
directories must be available and populated with all files from all installation
CD-ROMs.
Note
The directory specified in the following refers to
/location/of/disk/space/
.
This means it is the directory up to, but not including, the
RedHat/
distribution
