4 Chapter 1. Steps to Get You Started

1.4. Preparing for a Hard Drive Installation

Note

DASD installations only work from ext2 or ext3 ﬁle systems. If you have a ﬁle system other than ext2

or ext3 you will not be able to perform a DASD installation.

To prepare your system for a hard drive installation, you must set the system up in one of the following

ways:

• Using a set of CD-ROMs — Create CD-ROM ISO image ﬁles from each installation CD-ROM.

For each CD-ROM, execute the following command on a Linux system:

dd if=/dev/cdrom of=/tmp/file-name.iso

This command may raise an error message when the data at the end of the CD-ROM is reached

which can be ignored. The ISO images created can now be used for installation, once copied to the

correct DASD.

• Using ISO images — transfer these images to the system to be installed (or to the correct DASD).

Verifying that ISO images are intact before you attempt an installation, helps to avoid problems.

To verify the ISO images are intact prior to performing an installation, use an md5sum program

(many md5sum programs are available for various operating systems). An md5sum program should

be available on the same Linux machine as the ISO images.

Make the correct DASDs accessible to the new VM or LPAR, and then proceed with installation.

Additionally, if a ﬁle called RedHat/base/updates.img exists in the directory from which you

install, it is used for installation program updates. Refer to the ﬁle install-methods.txt in the

anaconda RPM package for detailed information on the various ways to install Red Hat Enterprise

Linux, as well as how to apply the installation program updates.

1.5. Installing under z/VM

Log onto z/VM as the Linux guest account. You can use x3270 or c3270 (from the x3270-text package

in Red Hat Enterprise Linux) to log in to z/VM from other Linux systems. Alternatively, use the OS/2

3270 terminal emulator on the S/390 management console. If you are working from a Windows based

machine, Jolly Giant (http://www.jollygiant.com/) offers an SSL-enabled 3270 emulator.

If you are not in CMS mode, enter it now.

i cms

If necessary, add the device containing z/VM’s TCP/IP tools to your CMS disk list. For example:

vmlink tcpmaint 592 592

If using any of the qdio/qeth based network connection types (such as OSA express or hipersockets),

set the VM guest qioassist parameter off:

set qioassist off

FTP to the machine containing the Red Hat Enterprise Linux boot images (kernel.img and

initrd.img), log in, and execute the following commands (use the (repl option if you are

overwriting existing kernel.img and initrd.img image ﬁles):

1 2 ... 7 8 9 10 11 12 13 14 15 16 17 ... 85 86
