Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
.Hard drive partitioned installations with iso9660 filesystem fails
You cannot install RHEL on systems where the hard drive is partitioned with the `iso9660` filesystem. This is due to the updated installation code that is set to ignore any hard disk containing a `iso9660` file system partition. This happens even when RHEL is installed without using a DVD.
To workaround this problem, add the following script in the kickstart file to format the disc before the installation starts.
Note: Before performing the workaround, backup the data available on the disk. The `wipefs` command formats all the existing data from the disk.

----
%pre
wipefs -a __/dev/sda__
%end
----
As a result, installations work as expected without any errors.

Description of problem:
When the hard drive contains a preloaded CDROM image, the system cannot be installed, due to python-blivet excluding any hard disk containing a iso9660 file system partition.
This happens even when the installation is performed without using a DVD at all.
The reason for this seems new detection code introduced with 8.3
Version-Release number of selected component (if applicable):
anaconda-33.16.3.26-1.el8
How reproducible:
ALWAYS
Steps to Reproduce:
1. Attach a disk to a VM and copy a DVD on it
# dd if=/dev/sr0 of=/dev/sdb bs=10M
2. Detach the disk and attach it to a new VM to install
The VM was configured with a DVD drive (unused), but this doesn't change anything.
3. Install the system using a kickstart (/run/install/ks.cfg in anaconda.tar.gz)

Expected results:
/dev/sda gets repartitioned and system installs
Additional info:
This is a critical issue for customers deploying system booting on a pre-initialized hard disk hosting a pre-boot environment.
The disk is also not visible in UI during manual installation.
A workaround for kickstart installation is to clean the disk in %pre script, for example:
%pre
wipefs -a /dev/sda
%end
