Are you sure iser transport is created on target login? There is no iser modules within XS open-iscsi, so whilst the kernel modules loads, open-iscsi has no means to make a connection over iser.
Can you try logging out of iscsi targets, and try from the command link to log into target like this.
iscsiadm -m discovery -t st -p 10.0.0.1 -I iser
iscsiadm -m node -T iqn.2010-10.com.example:storage-1000 -l
Let me know how it connects.
