Installation guide

Warning
If you receive an error after the Disk Partitioning Setup phase of the installation saying
something similar to:
"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."
you may not have a partition table on that drive or the partition table on the drive may not be
recognizable by the partitioning software used in the installation program.
Users who have used programs such as EZ - BIO S have experienced similar problems,
causing data to be lost (assuming the data was not backed up before the installation began).
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
single path storage to multipath storage is not supported. You must perform a new installation
to move the root file system to a multipath storage device. Therefore you should plan your
installation accordingly. See https://access.redhat.com/site/solutions/66501 for more
information.
