DefaultTime2Retain is a parameter that is being negotiated between the target and the initiator, and the _minimum_ of proposed DefaultTime2Retain values wins. The default DefaultTime2Retain for open-iscsi is 0, thus if the initiator proposes 0 and the target 60, 0 wins. You'll have to set this on the initiator and the target. Florian
