Description of problem: Rhevh which is installed in software iscsi can not reboot successfully after register to rhevm3.4. It will hang on determine rhevm ip process and report the error like follows. -------------------------------------------------------------------------------- iscsi:10.66.8.222::3260::iqn.2013-01.com:hadong iscsistart: Logging into iqn.2013-01.com:hadong 10.66.8.222:3260,1 iscsistart: can not connect to iSCSI daemon (111)! iscsistart: version 6.2.0-873.10.el6 iscsistart: Connection1:0 to [target: iqn.2013-01.com:hadong, portal: 10.66.8.222,3260] through [iface: default] is operational now mkdir: cannot create directory `/dev/.initramfs/': File exists Welcome to Red Hat Enterprise Virtualization Hypervisor Starting udev: G[ OK ] Setting hostname localhost.localdomain: [ OK ] Setting up Logical Volume Management: 4 logical volume(s) in volume group "HostVG" now active [ OK ] cp: `/etc/sysconfig/network-scripts' and `/var/lib/stateless/writable/etc/sysconfig/network-scripts' are the same file Mounting local filesystems: [ OK ] Enabling /etc/fstab swaps: [ OK ] Entering non-interactive startup Starting ovirt-early: [ OK ] Calling the system activity data collector (sadc)...

So just try to change the cmdline as follows and reboot can be succeed. root=live:LABEL=Root netroot=iscsi:10.66.8.222::3260::iqn.2013-02.com:hadong ip=rhevmhcp bridge=rhevm:em1 ksdevice=bootif RD_NO_LVM crashkernel=128M lang= rd_NO_LUKS max_loop=256 kssendmac rd_NO_MD quiet elevator=deadline rhgb rd_NO_DM Version-Release number of selected component (if applicable): rhev-hypervisor6-6.5-20140624.0.el6ev ovirt-node-3.0.1-18.el6_5.11.noarch How reproducible: 100% Steps to Reproduce: 1. Install rhevh with software iscsi as follow parameters. BOOTIF=em1 storage_init=/dev/sda,/dev/sdb iscsi_init=/dev/sdb iscsi_install iscsi_server=10.66.8.222:3260 iscsi_target_name=iqn.2013-02.com:hadong firstboot 2. Register to rhevm3.4 3. Reboot rhevh Actual results: 1. Rhevh hangs on reboot process and report the errors infos. Expected results: 1. Rhevh can reboot successfully. Additional info:
