Liron/Greg, is this related to bug 1176402?
(In reply to Allon Mureinik from comment #1) > Liron/Greg, is this related to bug 1176402? Unsure. I'm figuring out (with Ori) if/how I can reproduce the issue and won't know more until then.

Hi Yaniv, I can't reproduce it in my dev environment, so I'm getting a virt host that can connect to the tested storage and will debug/fix it from there. (Same applies for bug 1164578 as well)
3.5.1 is already full with bugs (over 80), and since none of these bugs were added as urgent for 3.5.1 release in the tracker bug, moving to 3.5.2

This bug is Verfied on latest 3.6 rhevm build (12)
Verified on latest oVirt 3.5 and latest Rhevm 3.6. note: iscsi connection are not doubled any more but the final result of this flow differs from 3.5 to 3.6. while in 3.6 'hypervisor A' which is detaching iscsi domain and "left" with only file storage has no iscsi connection upon detach. in 3.5 'hypervisor A' left with redundant connections upon detach: root@el71-host01 ~ $ iscsiadm -m session tcp: [11] 10.35.160.106:3260,3 iqn.1992-04.com.emc:cx.ckm00121000438.b6 (non-flash) tcp: [6] 10.35.160.107:3260,4 iqn.1992-04.com.emc:cx.ckm00121000438.b7 (non-flash) tcp: [8] 10.35.160.105:3260,2 iqn.1992-04.com.emc:cx.ckm00121000438.a7 (non-flash)
We didn't get 3.5.5 rhevm build yet - therefore it wasn't verified on the relevant build. Back to on_qa to verify once we will have 3.5.5 downstream build.
Verified on 3.6 based on comment #8
