Kernel command line:

BOOT_IMAGE=/ostree/rhel-atomic-host-5dfb4e57904b41f15d098be05bcc6b80feedf3961c1f916f18daffcd2e8d5058/vmlinuz-3.10.0-227.el7.x86_64 netroot=iscsi:@ netroot=iscsi:@ vconsole.keymap=us iscsi_initiator=iqn.1994-05.com.redhat:933d2fb45553 rd.lvm.lv=rah_system1/swap rd.lvm.lv=rah_system1/root crashkernel=auto vconsole.font=latarcyrheb-sun16 ifname=eth0:52:54:00:12:34:56 ip=eth0:dhcp root=/dev/mapper/rah_system1-root ostree=/ostree/boot.0/rhel-atomic-host/5dfb4e57904b41f15d098be05bcc6b80feedf3961c1f916f18daffcd2e8d5058/0 console=ttyS0 rd.debug

ifname=eth0:52:54:00:12:34:56 should never be on the kernel command line.

try "ifname=myeth0:52:54:00:12:34:56 ip=myeth0:dhcp"

Nevertheless, the initramfs of the atomic host does not seem to have iSCSI support.

Hi Milan, 

This commit in the 7.1_BETA branch of the Release Notes contains the description from the Doc Text field:

bfdca07 Added 4 Known Issues for Atomic.


Comment 6 Harald Hoyer 2015-06-01 12:54:42 UTC
Colin Walters, can we reassign this bug to something else than dracut? Clearly, it is not the fault of dracut, that the atomic host has no support for iSCSI.
