John,
Thanks for reply. The Discover function in GUI works...it's once I try and
login (Click the array next to target) that things just hang indefinitely.
# iscsiadm -m session
tcp: [2] 10.0.0.10:3260,1
iqn.2014-04.edu.tamu.brazos.vmstore1:ovirt-data_iscsi
# iscsiadm -m node
10.0.0.10:3260,1 iqn.2014-04.edu.tamu.brazos.vmstore1:ovirt-data_iscsi
# multipath -ll

`- 3:0:0:0 sdc 8:32 active ready running
The first entry, 1IET_00010001 is the iSCSI LUN.
The log when I click the array in the interface for the target is this:

The lines prefixed with "Thread-13" just repeat over and over only changing
the Task value.
Unsure what could be done to restore things. The iscsi connection is good
and I'm able to see the logical volumes:
