I'm attempting to add iSCSI storage to a data center via web interface, and while I"m able to see the target ISCSI device and login, clicking the "OK" button doesn't submit the storage selection. I noticed from looking at the oVirt manual that somewhere in this interface I have to select the LUN. However once logged into the target I never see LUNs to select. I've attached two screenshots that show the UI and what could be errors in how it's being displayed. I also attached logs from vdsm host and engine that were captured while attempting to add the storage domain. After logging into the iSCSI target via web interface, this is the output on target host, showing that my ovirt node (10.20.1.240) is connected. # tgtadm --lld iscsi --op show --mode target Target 1: iqn.2012-06.edu.tamu.dc-store:lv_kvm_pool System information: Driver: iscsi node dc-store0.tamu.edu State: ready I_T nexus information: I_T nexus: 3 Initiator: iqn.1994-05.com.redhat:ad499aa5f37e Connection: 0 IP Address: 10.20.1.240 LUN information: LUN: 0 Type: controller SCSI ID: IET 00010000 SCSI SN: beaf10 Size: 0 MB, Block size: 1 Online: Yes Removable media: No Readonly: No Backing store type: null Backing store path: None Backing store flags: LUN: 1 Type: disk SCSI ID: p_lu_coraid23_lu SCSI SN: (stdin)= Size: 4398047 MB, Block size: 512 Online: Yes Removable media: No Readonly: No Backing store type: rdwr Backing store path: /dev/vg_coraid23/lv_kvm_pool Backing store flags: Account information: ACL information: ALL Based on some archived emails I've included previously mentioned outputs that may help

From the ovirt node:
