Doc Text:
Cause: if "ip=ibft" is specified as a kernel command line argument, but no "ifname=<iface>:<mac>", dracut does not handle network interfaces. Consequence: iSCSI disks will not be connected to the system and the system does not boot. Fix: dracut now handles "ip=ibft" as a kernel command line argument, even without "ifname=<iface>:<mac>". Result: iSCSI disks will be connected to the system and the system boots.

Description Marius Boeru 2014-02-24 16:14:10 UTC 
Description of problem:
if no ifname is specified as kernel argument the server will not boot using ip=ibft. It will not find iscsi the root device

Version-Release number of selected component (if applicable): CentOS 6.5


How reproducible:


Steps to Reproduce:
1.Install CentOS using netinstall iso on an iscsi lun
2. after instalation remove ifname=eth0:XX:XX:XX:XX:XX:XX from kernel line
3. try to boot and it will fail

Actual results:
rdinitdebug boot log and init.log: http://pastebin.com/XY4Ahwam

Expected results:
The OS should be able to boot only with ip=ibft and no ifname parameter

Additional info:

dirty fix: set ifname=dummy:FF:FF:FF:FF:FF:FF (or anything else in the same format) as a parameter and the OS will boot from iscsi and will set ibft0 accordingly
