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
