4.2. Deployment

  • In Red Hat Enterprise Linux 6.1, multilib Python packages and packages dependent on them have been removed. This was because installing Python packages for multiple architectures on one system can cause various problems. For more information, refer to
  • Some HP Proliant servers may report incorrect CPU frequency values in /proc/cpuinfo or /sys/device/system/cpu/*/cpufreq. This is due to the firmware manipulating the CPU frequency without providing any notification to the operating system. To avoid this ensure that the "HP Power Regulator" option in the BIOS is set to "OS Control". An alternative available on more recent systems is to set "Collaborative Power Control" to "Enabled".
  • Some packages in the Optional repositories on RHN have multilib file conflicts. Consequently, these packages cannot have both the primary architecture (e.g. x86_64) and secondary architecture (e.g. i686) copies of the package installed on the same machine simultaneously. To work around this, install only one copy of the conflicting package.
  • When rebuilding the grub package on the x86_64 architecture, the glibc-static.i686 package must be used. Using the glibc-static.x86_64 package will not meet the build requirements.
  • Parted in Red Hat Enterprise Linux 6 cannot handle Extended Address Volumes (EAV) Direct Access Storage Devices (DASD) that have greater than 65535 cylinders. Consequently, EAV DASD drives cannot be partitioned using parted, and installation on EAV DASD drives will fail. To work around this issue, complete the installation on a non EAV DASD drive, then add the EAV device after installation using the tools provided in s390-utils.
