Installation guide

Note
If you have a RAID card, be aware that some BIOSes do not support booting from the RAID
card. In cases such as these, the /boot/ partition must be created on a partition outside of
the RAID array, such as on a separate hard drive. An internal hard drive is necessary to use
for partition creation with problematic RAID cards.
A /boot/ partition is also necessary for software RAID setups.
If you have chosen to automatically partition your system, you should select Review and
manually edit your /boot/ partition.
To review and make any necessary changes to the partitions created by automatic partitioning,
select the Review option. After selecting Review and clicking Next to move forward, the partitions
created for you in Disk Dru id appear. You can make modifications to these partitions if they do not
meet your needs.
Click Next once you have made your selections to proceed.

If you chose one of the three automatic partitioning options and did not select Review, skip ahead to
Section 4.21, “ Network Configuration” .
If you chose one of the automatic partitioning options and selected Review, you can either accept
the current partition settings (click Next), or modify the setup using Disk Dru id , the manual
partitioning tool.
Note
Please note that in the text mode installation it is not possible to work with LVM (Logical
Volumes) beyond viewing the existing setup. LVM can only be set up using the graphical Disk
Druid program in a graphical installation.
If you chose to create a custom layout, you must tell the installation program where to install Red Hat
Enterprise Linux. This is done by defining mount points for one or more disk partitions in which Red
Hat Enterprise Linux is installed. You may also need to create and/or delete partitions at this time.
Note
If you have not yet planned how to set up your partitions, refer to Chapter 26, An Introduction to
Disk Partitions and Section 4.19.4, “ Recommended Partitioning Scheme”. At a bare minimum,
you need an appropriately-sized root partition, and a swap partition equal to twice the amount
of RAM you have on the system. Itanium system users should have a /boot/efi/ partition of
approximately 100 MB and of type FAT (VFAT), a swap partition of at least 512 MB, and an
appropriately-sized root (/) partition.
