Chapter 20. Installation and Booting
The installer displays the number of multipath devices, and number of multipath devices selected, incorrectly
Multipath devices are configured properly, but the installer displays the number of devices and number of selected devices incorrectly. There is no known workaround at this point. (BZ#914637)
The installer displays the amount of disk space within multipath devices incorrectly
Multipath devices are configured properly, but the installer displays disk space and number of devices incorrectly. There is no known workaround at this point. (BZ#1014425)
The device.map configuration file generated by Anaconda is sometimes incorrect
Due to limitations in the kernel, the
device.map configuration file that is used to map BIOS drives to operating system devices might be generated incorrectly in certain situations, particularly when installing from a USB key. As a consequence, booting sometimes fails after installation. To work around this problem, manually update the device.map file in the /boot/grub directory. After updating device.map so that it correctly maps devices on the system, Red Hat Enterprise Linux 6 will boot as expected. (BZ#1253223)
The ifup script incorrectly replaces manually-defined default routes
If a default route is manually added to the routing table, the
ifup script incorrectly replaces it, when setting up other interfaces, if the GATEWAY parameter is specified. To work around this bug, specify a non-zero metric for either the manually-added route, or when adding a route with ifup. (BZ#1090559)
Upgrading Red Hat Enterprise Linux 6 on UEFI systems clears the boot loader password
When upgrading Red Hat Enterprise Linux 6 on a system with UEFI firmware and a boot loader password set, the boot loader password is removed. As a consequence, modifying the boot record is possible without a password. To work around this problem, make a back up of the password settings from the
/boot/efi/EFI/redhat/grub.conf configuration file before upgrading, and then restore the settings to the /boot/efi/EFI/redhat/grub.conf file in the new system. (BZ#1416653)
