Tip
Additional information on the iSeries can be found online at:
http://www-1.ibm.com/servers/eserver/iseries/linux/
To prepare your iSeries system for installation, follow the instructions in the Planning
to run Linux on a logical partition and Creating a logical partition to run Linux
sections
of
the
OS/400 command documentation for information on configuring the OS/400 facilities
(http://publib.boulder.ibm.com/iseries/v5r2/ic2924/info/rbam6/rbam6clmain.htm). The basic steps
for installation preparation on your iSeries are as follows:
First, create a Logical Partition in SST using the screens in Work with system partitions. The par-
tition must be of type Guest, have some amount of processor and memory, and either a native LAN
adapter or virtual Ethernet assigned. After you create your Linux partition, assign a hosting partition
to it. Select option 13 on the new Linux partition in the Work with Partition Configuration screen.
Next, IPL your primary partition after creating the new partition.
If you are using shared processors with V5R2 OS/400, you can dynamically change the amount of
processor units assigned to your partition, as long as it is within the minimum and maximum processor
units you have set for your partition. You cannot dynamically go below a minimum of 0.10 times the
number of processors. Changing the processor or memory limits requires a Primary Partition IPL.
Next, create an NWSD by executing the command
Partition field has the name of the Logical Partition you created in SST; it should be of type Guest and
Codepage 437. For a basic NWSD, use
the other fields — the boot fields are setup in Section 2.1.1 Booting the iSeries Installation Program.
Assuming you plan on using a virtual disk rather than native SCSI using the ibmsis driver, create
an NWSSTG (virtual disk) by executing the command
Once you create it, you must add a link to the NWSD you created using the name of the NWSD.
1.4. Do You Have Enough Disk Space?
Nearly every modern-day operating system (OS) uses disk partitions, and Red Hat Enterprise Linux is
no exception. When you install Red Hat Enterprise Linux, you may have to work with disk partitions.
If you have not worked with disk partitions before (or need a quick review of the basic concepts), refer
to Appendix C An Introduction to Disk Partitions before proceeding.
The disk space used by Red Hat Enterprise Linux must be separate from the disk space used by other
OSes you may have installed on your system.
Before you start the installation process, one of the following conditions must be met:
Your computer must have enough unpartitioned
•
prise Linux.
You must have one or more partitions that may be deleted, thereby freeing up enough disk space to
•
install Red Hat Enterprise Linux.
To gain a better sense of how much space you really need, refer to the recommended partitioning sizes
discussed in Section 2.15.4 Recommended Partitioning Scheme.
1. Unpartitioned disk space means that available disk space on the hard drive(s) you are installing to has not
been divided into sections for data. When you partition a disk, each partition behaves like a separate disk drive.
