Hi,
some facts:
ovirt-node 4.3.10 (based on Centos 7)
hosts are HP blades BL460C with network card supporting iscsi HBA (there are no iscsi nics
visible on OS level, but i had to configure ip addresses manually since they were not
inherited from BIOS )

target SAN storage is detected, and exposed LUNs are visible. I can even partition them,
create filesystem and mount them in OS, all when doing manually step by step.
when trying to add Storage Domain in iscsi the LUNs/targets are nicely visible in GUI, buf
after choosing a LUN the domain becomes locked and finally enters detatched mode. can not
attach the Datacenter.
in engine.log similar entry for each host:

execution failed: VDSGenericException: VDSNetworkException: Message timeout which can be
caused by communication issues
how to make it working?
I read offload iscsi is supported but all the documentation i found is for software
iscsi.
any hints welcomed
thanks
