During an MPATH installation of RHEL 6 on a POWER 7 system, a "DiskLabelCommit Error" may occur

Updated -

During an MPATH installation on an IBM POWER 7 system, the following error may occur: "DiskLabelCommit Error".
Workaround:

  1. Install in a single path configuration.
  2. Note both the system IP address and the server IP address after network setup.
  3. ssh into the system and clear up the partitions via 'fdisk -l', and delete the partitions. Making sure all partitions are deleted, exit out.
  4. Continue the installation from the installer.

This issue is documented in the RHEL 6 Technical Notes, and is represented by Red Hat Bugzilla #639446.
