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 Bradley Gartside 2014-07-22 17:31:44 UTC 
Description of problem:

     While following the Red Hat Enterprise Linux 7 Installation Guide for the default installation, the install process fails with the following console output:

     dracut-initqueueÝ573¨: Warning: Could not boot.   
     dracut-initqueueÝ573¨: Warning: /dev/root does not exist 
              Starting Dracut Emergency Shell... 
     Warning: /dev/root does not exist 
 
     Generating "/run/initramfs/rdsosreport.txt" 
 
 
     Entering emergency mode. Exit the shell to continue. 
     Type "journalctl" to view system logs. 
     You might want to save "/run/initramfs/rdsosreport.txt" to a USB
     stick or /boot after mounting them and attach it to a bug report. 
 
 
     dracut:/# 



Version-Release number of selected component (if applicable):
     Linux version 3.10.0-123.el7.s390x
     (mockbuild.bos.redhat.com)
     (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16)
     (GCC) ) #1 SMP Mon  May 5 11:18:08 EDT 2014

How reproducible:
     This happens every time with the kernel (kernel.img) and initial RAM disk
	(initrd.img) and generic.prm provided in the rhel-server-7.0-s390x-dvd.iso

Steps to Reproduce:
13.2.1. Booting the Installation
	After establishing a connection with the mainframe, you need to perform an initial program load (IPL), or boot, from the medium containing the installation program. T his document describes the most common methods of installing Red Hat Enterprise Linux on System z. In general, you can use any method to boot the Linux installation system, which consists of a kernel (kernel.img) and initial RAM disk (initrd.img) with at least the parameters in the generic.prm file.


Actual results:
dracut-initqueueÝ573¨: Warning: Could not boot.   
dracut-initqueueÝ573¨: Warning: /dev/root does not exist 
         Starting Dracut Emergency Shell... 
Warning: /dev/root does not exist 
 
Generating "/run/initramfs/rdsosreport.txt" 
 
 
Entering emergency mode. Exit the shell to continue. 
Type "journalctl" to view system logs. 
You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot
after mounting them and attach it to a bug report. 
 
 
dracut:/# 

Expected results:

I expect to see something like this:

Scanning for available network devices... 
Autodetection found 0 devices. 
Note: There is a device blacklist active! (Clearing might take long)
c) clear blacklist, m) manual config, r) rescan, s) shell:

Comment 2 Anton Chernomaz 2014-07-27 12:07:04 UTC 
Got very similar on Supermicro

I am trying to kickstart RH7.0 on this server and receive same error
while on othere servers (from different vendors) no such problem

my pxe line:
LABEL RH7.0x64_hpc
      kernel RH/7.0/GA/x86_64/vmlinuz
      append initrd=RH/7.0/GA/x86_64/initrd.img ks=http://webrepo/confs/RH/7.0/GA/x86_64/ksnew-hpc.cfg ksdevice=bootif
      IPAPPEND 2

this link not helps,though it looks similar:
https://access.redhat.com/solutions/647943
Comment 3 Harald Hoyer 2014-08-14 12:27:04 UTC 
Please add "rd.debug" to the kernel command line and attach the rdsosreport from that boot for further debugging.

Reassigning to anaconda for comments on the completeness of the kernel command line parameters.
Comment 4 David Cantrell 2014-10-30 17:29:55 UTC 
Kernel parameters noted in the opening comment are sufficient for s390x.  You can see the default parameters shipped with the RHEL-7 s390x media in the images/generic.prm file.
Comment 5 Harald Hoyer 2014-11-04 14:53:54 UTC 
(In reply to David Cantrell from comment #4)
> Kernel parameters noted in the opening comment are sufficient for s390x. 
> You can see the default parameters shipped with the RHEL-7 s390x media in
> the images/generic.prm file.

from comment #1:
+ cat /proc/cmdline 
ro ramdisk_size=40000 cio_ignore=all,!condev 

Well, I don't see any "root=.." kernel command line parameter, nor any other predefined parameters, except:

from comment #1:
+ cat /etc/cmdline.d/99-anaconda-disable-disk-activation.conf 
rd.dm=0 
rd.md=0 
rd.lvm=0 
rd.luks=0 


So, how the heck should this work?
Comment 6 RHEL Program Management 2014-12-12 20:25:50 UTC 
Development Management has reviewed and declined this request.
You may appeal this decision by reopening this request.
Comment 7 blackhawk 2019-03-05 14:10:51 UTC 
Hi all,

I encountered the similar problem when trying to install rhel7.6 on an IBM z System lpar(z13).
Below is the console messages:
