Anaconda doesn't create a new PPC PRep Boot partition on systems with existing PReP partitions on other disks
Updated -
The following issue applies to IBM Power Systems only, and is also documented in the RHEL 6 Technical Notes.
anaconda will not create a new PReP boot partition on the root disk when performing a new Red Hat Enterprise Linux 6 installation on a system that contains existing PReP Boot partitions that need to be preserved. Consequently, the Power SMS boot manager will be unable to boot the new Red Hat Enterprise Linux 6 installation.
To work around this issue:
- Use the fdisk utility to temporariy change the partion type from type 41 'PReP Boot' to type 83 'Linux' for all existing Linux installations on the system.
- Perform the Red Hat Enterprise Linux 6 installation. During installation, a new PReP Boot partition will be created on the Red Hat Enterprise Linux 6 root disk.
- Post-installation, once the new Red Hat Enterprise Linux 6 installation is up and running, use the fdisk utility to restore all changed partition types to type 41 'PReP Boot'.
This issue is documented in the RHEL 6 Technical Notes, and is represented by Red Hat Bugzilla # 625831.
