Steps to Get You Started
16.1. Pre-Installation
The installation process assumes a basic familiarity with the IBM eServer System z platforms. For
additional information on these platforms, refer to the IBM Redbooks available online at:
http://www.redbooks.ibm.com/

This manual assumes you are familiar with the related Redbooks and can set up logical partitions
(LPARs) and virtual machines (VMs) on an IBM eServer System z system.

Before you install Red Hat Enterprise Linux, you must perform the following steps:
1. Allocate sufficient Disk Storage Space using
DASDs
2
or
SCSI
3
partitions to provide suitable disk
space (for example, 2 GB is sufficient for server installations, while 5 GB is minimally required to
install all packages).
2. Acquire a minimum of 512 MB RAM (1 GB is strongly recommended) to designate for the Linux
virtual machine.
3. Determine if you need swap space and if so how much. While it is possible (and recommended)
to assign enough memory to z/VM and let z/VM do the necessary swapping, there may be cases
where the amount of required RAM is not predictable. Such instances should be examined on a
case-by-case basis.
4. Decide on the environment under which to run the operating system (on an LPAR or as a guest
operating system on one or more virtual machines).
5. Finally, it is important to review sections 3.3 through 3.8, and Chapters 5 and 6 of the
IBM Linux
for System z Redbook
, as it explains the different configurations and install scenarios available on
the zSeries platform as well as how to setup an initial LPAR or Linux virtual machine (z/VM).
16.2. Additional Hardware Preparation for System z
The network configuration must be determined beforehand. Red Hat Enterprise Linux for IBM System
z supports QDIO-enabled (Queued Direct I/O) and LCS (LAN channel station) devices. The CTC
(channel-to-channel) and IUCV (inter-user communication vehicle) are deprecated and are not
supported in Red Hat Enterprise Linux.
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 IBM System z SCSI LUNs)
