dracut
component
For Fibre Channel over Ethernet (FCoE) from SAN on Dell systems which enable biosdevname=1 by default, udev typically renames all network interfaces to their biosdevname naming convention during boot. However, a bug in udev prevents the FCoE boot interface from being renamed. This can result in occasional shutdown stalls. In order to install and shut down the system correctly, it is recommended to use the biosdevname=0
installation parameter to avoid biosdevname naming in this case.
dracut
component
For iSCSI boot from SAN on Dell systems which enable settingbiosdevname=1
by default, the installation completes successfully, but the system will not be able to mount the rootfs partition after reboot. This is because of a bug in Dracut where the boot network interface is not brought up if biosdevname naming is used. In order to install and reboot the system successfully in this case, use the biosdevname=0
installation parameter to avoid biosdevname naming.

Setting the qla4xxx parameter ql4xdisablesysfsboot
to 1
may cause boot from SAN failures.

To automatically create an appropriate partition table on disks that are uninitialized or contain unrecognized formatting, use the zerombr
kickstart command. The --initlabel
option of the clearpart
command is not intended to serve this purpose.
anaconda
component, BZ#676025
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).

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 sda
).
During installation, verify the storage device size, name, and type when configuring partitions and file systems.

kernel
component
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.

The 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.
firstaidkit
component
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, an 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.

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.
yaboot
component, BZ#613929
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.
system-config-kickstart
component
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.
