Start the NFS daemon (on a Red Hat Enterprise Linux system, use
/sbin/service nfs start
).
If NFS is already running, reload the configuration file (on a Red Hat Enterprise Linux system use
/
sbin/service nfs reload
).
Be sure to test the NFS share following the directions in the Red Hat Enterprise Linux Deployment
Guide.
16.5. Preparing for a Hard Drive Installation
Note
Hard drive installations using DASD or SCSI source storage only work from native ext2 or
ext3 partitions. If you have a file system based on devices other than native ext2 or ext3
(particularly a file system based on RAID or LVM partitions) you will not be able to use it
as a source to perform a hard drive installation.
Ensure that you have boot media available on CD, DVD, or a USB storage device such as a flash
drive.
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, or a DVD — Create ISO image files from each installation CD-ROM, or
from the DVD. For each CD-ROM (once for the DVD), 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 to the system to be installed (or to the correct DASD or SCSI
devices).
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 or SCSI LUNs accessible to the new VM or LPAR, and then proceed with
installation.
Additionally, if a file called
updates.img
exists in the location from which you install, it is used for
updates to
anaconda
, the installation program. 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.
