I'm trying to setup the hosted engine on top of iSCSI storage. It successfully logs in and gets the target, however the process errors out claiming there are no LUNs. But if you look on the host, the disks were added to the system.

[ INFO  ] TASK [ovirt.hosted_engine_setup : iSCSI discover with REST API]
[ INFO  ] ok: [localhost]
          The following targets have been found:
                [1]     iqn.2001-04.com.billdurr.durrnet.vm-int:vmdata
                        TPGT: 1, portals:
                                192.168.47.10:3260

          Please select a target (1) [1]: 1
[ INFO  ] Getting iSCSI LUNs list
...
[ INFO  ] TASK [ovirt.hosted_engine_setup : Get iSCSI LUNs]
[ INFO  ] ok: [localhost]
[ ERROR ] Cannot find any LUN on the selected target
[ ERROR ] Unable to get target list

Here's what the config in targetcli looks like
[root@vm1 ~]# targetcli ls

The two LUNs show up on the host after the hosted engine setup tries to enumerate the LUNs for the target
