Description Jan Stodola 2015-03-05 16:29:23 UTC
Description of problem:
Provisioning of RHEL-7.1/s390x using Satellite 5.7 fails when the installation is starting.
The installation fails because of wrong parameters on the kernel command line:

1) "ip"
"ip" without any value is refused by dracut
2) "root=/dev/ram0"
this parameter must not be present on the kernel command line when installing RHEL-7 on s390x.

Created boot record in /etc/zipl.conf contains:
        parameters="ksdevice=link lang= CMSDASD=191 ip RUNKS=1 root=/dev/ram0 ks=http://something1.redhat.com/cblr/svc/op/ks/system/something2.redhat.com:1 ramdisk_size=40000 CMSCONFFILE=r7.conf text vnc ro kssendmac "

Version-Release number of selected component (if applicable):
Red Hat Satellite release 5.7.0

How reproducible:
always on s390x

Steps to Reproduce:
1. create a kickstart for provisioning RHEL-7.1
2. enter "CMSDASD=191 CMSCONFFILE=r7.conf" to the "Kernel Options" field under Kickstart Details -> Details (this is where the network and disk configuration is stored on our systems)
3. provision an s390x system using the kickstart

Actual results:
wrong kernel command line, system fails to install

Expected results:
successful installation, "ip" and "root=/dev/ram0" are not present on the installation kernel command line

Additional info:
* "root=/dev/ram0" has been removed from the installation kernel command line in RHEL-7.0, see bug 796572
* "root=/dev/ram0" is a valid parameter for RHEL-6 and earlier

Comment 2 Jan Stodola 2015-03-05 16:32:32 UTC
Workaround is to remove "ip" and "root=/dev/ram0" from /etc/zipl.conf and run "zipl" before rebooting to start the installation.
