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.
Description of problem:
On a RHEL 7.4 qcow2 cloud image, in order to boot using a iscsi root disk I've enabled the "iscsi" module in a dracut ramdisk and passed in rd.iscsi.firmware=1.
This works as expected and the image can now be booted over iscsi but the image can no longer be used to boot using a local disk. dracut times out waiting for a iscsi disk to be attached (see below).
In order to remove the need to have 2 slightly different images, the image should be capable to booting in both scenarios
This is now fixed in upstream dracut
https://github.com/dracutdevs/dracut/pull/298
Version-Release number of selected component (if applicable):
dracut-033-502.el7.x86_64
dracut-network-033-502.el7.x86_64
iscsi-initiator-utils-6.2.0.874-4.el7.x86_64
iscsi-initiator-utils-iscsiuio-6.2.0.874-4.el7.x86_64
redhat-release-server-7.4-18.el7.x86_64
How reproducible:
every time
Steps to Reproduce:
Prepare a rhel qcow image to boot over iscsi by
1. adding the iscsi module to the ramdisk (in chroot)
yum install -y iscsi-initiator-utils-6.2.0.874-4.el7.x86_64 iscsi-initiator-utils-iscsiuio-6.2.0.874-4.el7.x86_64
dracut --force --add "network iscsi" /boot/initramfs-3.10.0-693.el7.x86_64.img 3.10.0-693.el7.x86_64
2. Edit the file /etc/default/grub and add rd.iscsi.firmware=1 to GRUB_CMDLINE_LINUX=…
3. reconfigure grub
guestfish -a /tmp/rhel-server-7.4-x86_64-kvm.qcow2 -m /dev/sda1 sh "/sbin/grub2-mkconfig -o /boot/grub2/grub.cfg"
4. Use this image to boot from local disk as would be the usual (e.g. on a openstack cloud)

Hi Derek,
Could you please check if the solution in new dracut package works for you? Preferably on RHEL-7.6 Beta candidate compose.
Thanks a lot
