Hi Norm, You should check the logs in the initiator side. You will need to increase the debug level of ib_iser to 2 to get relevant messages. In the target side please check the logical target is indeed configured for iser and the access list is configured to the right ip or to ALL.

Any attempt to connect to tgtd from a Centos 6.6 system with its included infiniband drivers fails. Server is The most obvious symptom of this is that when the initiator contacts the target, tgtd requests 1GB of shared memory, which fails: In response to initiatior: [root@e5node05 iscsi]# iscsiadm -m discovery -t sendtargets -p 192.168.170.188:3260 -I iser [root@e5san01 etc]# tgtd -f tgtd: work_timer_start(146) use timer_fd based scheduler tgtd: bs_init_signalfd(267) could not open backing-store module directory /usr/lib/tgt/backing-store tgtd: bs_init(386) use signalfd notification tgtd: iser_alloc_pool(571) shmget rdma pool sz:1073741824 failed tgtd: iser_cm_conn_established(1613) conn:0x12db840 cm_id:0x12beac0, 192.168.170.85 -> 192.168.170.188, established tgtd: iser_cm_disconnected(1633) conn:0x12db840 cm_id:0x12beac0 event:10, RDMA_CM_EVENT_DISCONNECTED tgtd: iser_conn_close(1292) conn:0x12db840 cm_id:0x0x12beac0 state: CLOSE, refcnt:394 tgtd: iser_cm_timewait_exit(1648) conn:0x12db840 refcnt:1 cm_id:0x12beac0 tgtd: iser_cm_timewait_exit(1666) conn:0x12db840 refcnt:1 cm_id:0x12beac0 (after cleanup) This happens with the stock tgtd 1.0.24, or the newest 1,0,55 tgtd (this listed above).
