Direct Access Storage Devices (or DASDs) are hard disks that allow a maximum of three (3) partitions per DASD. For
example, dasda has dasda[123] .

Using the zFCP driver over fiber and a dedicated switch, SCSI LUNs can be presented.
Steps to Get You Started
The installation process assumes a basic familiarity with the IBM S/390 and IBM eServer
zSeries platforms. For additional information on these platforms, refer to the IBM Redbooks
available online at:
http://www.redbooks.ibm.com/ [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 S/390 or IBM eServer zSeries system.

Before you install Red Hat Enterprise Linux, you must to perform the following steps:
1. Allocate sufficient DASD
1
or SCSI
2
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 256 MB RAM (512 MB 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 what environment under which to run the Red Hat Enterprise Linux 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 S/390 Redbook, as it explains the different configurations and install scenarios
available on the S/390 platform as well as how to setup an initial LPAR or Linux virtual
machine (z/VM).
