Users performing an upgrade using the Anaconda's text mode interface who do not have a boot loader already installed on the system, or who have a non-GRUB boot loader, need to select
Skip Boot Loader Configuration during the installation process. Boot loader configuration will need to be completed manually after installation. This problem does not affect users running Anaconda in the graphical mode (graphical mode also includes VNC connectivity mode).
Anaconda fails to install to partitions of size 2.2 TB and larger.
On s390x systems, you cannot use automatic partitioning and encryption. If you want to use storage encryption, you must perform custom partitioning. Do not place the
/boot volume on an encrypted volume.
The order of device names assigned to USB attached storage devices is not guaranteed. Certain USB attached storage devices may take longer to initialize than others, which can result in the device receiving a different name than you expect (for example,
sdc instead of
During installation, verify the storage device size, name, and type when configuring partitions and file systems.
Dell systems based on a future Intel processor with graphics acceleration require the selection of the
install system with basic video driver installation option. A future Red Hat Enterprise Linux 6.2.z Extended Update Support update will remove this requirement.
Recent Red Hat Enterprise Linux 6 releases use a new naming scheme for network interfaces on some machines. As a result, the installer may use different names during an upgrade in certain scenarios (typically
em1 is used instead of
eth0 on new Dell machines). However, the previously used network interface names are preserved on the system and the upgraded system will still use the previously used interfaces. This is not the case for Yum upgrades.
kdump default on feature currently depends on Anaconda to insert the
crashkernel= parameter to the kernel parameter list in the boot loader's configuration file.
The firstaidkit-plugin-grub package has been removed from Red Hat Enterprise Linux 6.2. As a consequence, in rare cases, the system upgrade operation may fail with unresolved dependencies if the plug-in has been installed in a previous version of Red Hat Enterprise Linux. To avoid this problem, the firstaidkit-plugin-grub package should be removed before upgrading the system. However, in most cases, the system upgrade completes as expected.

In some circumstances, disks that contain a whole disk format (for example, a LVM Physical Volume populating a whole disk) are not cleared correctly using the
clearpart --initlabel kickstart command. Adding the
--all switch—as in
clearpart --initlabel --all—ensures disks are cleared correctly.
During the installation on POWER systems, error messages similar to:
attempt to access beyond end of device
loop0: rw=0, want=248626, limit=248624
may be returned to
sys.log. These errors do not prevent installation and only occur during the initial setup. The file system created by the installer will function correctly.
When installing on the IBM System z architecture, if the installation is being performed over SSH, avoid resizing the terminal window containing the SSH session. If the terminal window is resized during the installation, the installer will exit and the installation will terminate.

The kernel image provided on the CD/DVD is too large for Open Firmware. Consequently, on the POWER architecture, directly booting the kernel image over a network from the CD/DVD is not possible. Instead, use yaboot to boot from a network.
The Anaconda partition editing interface includes a button labeled Resize. This feature is intended for users wishing to shrink an existing file system and an underlying volume to make room for an installation of a new system. Users performing manual partitioning cannot use the Resize button to change sizes of partitions as they create them. If you determine a partition needs to be larger than you initially created it, you must delete the first one in the partitioning editor and create a new one with the larger size.
Channel IDs (read, write, data) for network devices are required for defining and configuring network devices on IBM S/390 systems. However, system-config-kickstart—the graphical user interface for generating a kickstart configuration—cannot define channel IDs for a network device. To work around this issue, manually edit the kickstart configuration that system-config-kickstart generates to include the desired network devices.
During FCoE BFS installation, when an Ethernet interface goes offline after discovering the targets, FCoE link will never come up. This is because Anaconda creates an FCoE configuration file under
/etc/fcoe/ using biosdevname (new style interface naming scheme) for all the available Ethernet interfaces for FCoE BFS. However, it does not add the
ifname kernel command line for the FCoE interface that stays offline after discovering FCoE targets during installation. Because of this, during subsequent reboots, the system tries to find the old style ethX interface name in the
/etc/fcoe directory, which does not match with the file created by Anaconda using biosdevname. Therefore, due to the missing FCoE configuration file, an FCoE interface is never created on the Ethernet interface.
To avoid this problem, ensure that the Ethernet interface does not go offline during FCoE BFS installation.
If the Ethernet interface does go offline during installation after discovering the targets, add the following parameter to the kernel command line:
