Just to confirm a Targetname is created by /iscsi create iqn.2013-03.de.campusvl.v101.storage:shared-01.v101.campusvl.de If that is the case than I always had different target names and TPGT was always 1 because it is the default and I did not change it. > Please confirm that > iqn.2013-03.de.campusvl.v102.storage:shared-01.v102.campusvl.de is > configured with generate_node_acls=0, and that no active sessions from > the initiator has created a NodeACL with se_node_acl->dynamic_node_acl Confirmed.

Please note that there are duplicated packets in the pcap because I did a '-i any' the system has bonding configured. So I see the packet once for the physical interface and the bond interface. https://thomas.glanzmann.de/tmp/discovery.pcap And I can confirm in the sniffer that I got the discovery: Opcode: Text Response (0x24) Flags: 0x80 1... .... = F: Final PDU in sequence .0.. .... = C: Text is complete TotalAHSLength: 0x00 DataSegmentLength: 0x00000234 LUN: 0000000000000000 InitiatorTaskTag: 0x00000001 TargetTransferTag: 0xffffffff StatSN: 0x9dee00da ExpCmdSN: 0x00000002 MaxCmdSN: 0x00000002 Key/Value Pairs KeyValue: TargetName=iqn.2013-03.de.campusvl.v101.storage:shared-01.v101.campusvl.de KeyValue: TargetAddress=10.101.99.4:3260,1 KeyValue: TargetAddress=10.101.99.5:3260,1 KeyValue: TargetName=iqn.2013-03.de.campusvl.v101.storage:shared-02.v101.campusvl.de KeyValue: TargetAddress=10.101.99.4:3260,1 KeyValue: TargetAddress=10.101.99.5:3260,1 KeyValue: TargetName=iqn.2013-03.de.campusvl.v102.storage:shared-01.v102.campusvl.de KeyValue: TargetAddress=10.102.99.4:3260,1 KeyValue: TargetAddress=10.102.99.5:3260,1 KeyValue: TargetName=iqn.2013-03.de.campusvl.v102.storage:shared-02.v102.campusvl.de KeyValue: TargetAddress=10.102.99.4:3260,1 KeyValue: TargetAddress=10.102.99.5:3260,1 Please let me know what the behaviour should be than I dig into the code and write a patch.
