Warning
If you receive an error after the Disk Partitioning Setup phase of the installation saying

"The partition table on device hda was unreadable. To create new partitions it must be
initialized, causing the loss of ALL DATA on this drive."
No matter what type of installation you are performing, backups of the existing data on your
systems should always be made.
Important — multipath devices
To install Red Hat Enterprise Linux on a network device accessible through multiple paths,
deselect all local storage in the Select the drive(s) to use for this
installation window, and select a device labeled mapper/mpath instead.
Note that migrating the root file system of an existing Red Hat Enterprise Linux installation from

installation accordingly. See https://access.redhat.com/site/solutions/66501 for more
information.
