RHEL 6 install on POWER Systems: 'Re-initialize all' on 'Specialized Storage Devices' may fail

During installation, selection of "Specialized Storage Devices" followed by selection "Re-initialize all" option on selected installation disks may fail.
The workaround is to select installation options in following order:

1. "Basic Storage Devices"
2. Next
3. "Re-initialize all"
4. Back
5. "Specialized Storage Devices"
6. Select desired installation disks
7. "Re-initialize all"

Continue with the installation.

This issue is documented in the RHEL 6 Technical Notes, and is represented by Red Hat Bugzilla #640829.
