Hi, I have an oVirt 4.2.6.4 installation. I added a new Centos 7.5 host and a new, still uninitialized Data Center with shared storage. I then try to add a new iSCSI Data Storage Domain on this Data Center and I have selected to use the only host I have where the iSCSI target also resides, over a local device. command 'targetcli ls' outputs:
o- / ......................................................................................................................... [...]
  o- backstores .............................................................................................................. [...]
  | o- block .................................................................................................. [Storage Objects: 0]
  | o- fileio ................................................................................................. [Storage Objects: 0]

  |     | o- lun0 .......................................................... [pscsi/vicinityvolume (/dev/iof/vicinityvolume) (None)]

  |       o- 0.0.0.0:3260 ..................................................................................................... [OK]
  o- loopback ......................................................................................................... [Targets: 0]

iSCSI target is discovered successfully, login also works but then when I click 'OK' button nothing happens. The iSCSI initiator seems to have been created though. Command 'iscsiadm -m session' outputs: tcp: [1] 44.128.20.202:3260,1 iqn.2015-03.com.iofabric:vicinityvolume (non-flash)
Command 'lsblk' outputs:

sdf               8:80   0     3T  0 disk
sr0              11:0    1  1024M  0 rom

The sde device is the original device to which the iSCSI target points and sdf is the device created by the iSCSI initiator.
Any help would be appreciated.
