Comment 4 for bug 1793205

I have tried reproducing the issue https://bugs.launchpad.net/cinder/+bug/1536248 on next environment:
MOS7.0 + MU8 updates
Cinder host:
Ubuntu 14.04
cinder-volume 1:2015.1.1-1~u14.04+mos3062
python-cinderclient 1:1.1.2-1~u14.04+mos323
python-rtslib-fb 2.1.45-4~u14.04+mos2
python2.7 2.7.6-8ubuntu0.4
linux-image-generic 3.13.0.158.168

I have performed the next steps:
1) Setup iscsi_helper = lioadm in /etc/cinder/cinder.conf
2) Create Volume and attach it to test VM
3) Reboot the Cinder node without stopping test VM
4) On compute node see in syslog:
root@node-4:~# tail -f /var/log/syslog
<27>Sep 26 09:20:47 node-4 iscsid: connect to 192.168.1.1:3260 failed (Connection refused)
<3>Sep 26 09:22:18 node-4 kernel: [71162.848123] sd 2:0:0:0: rejecting I/O to offline device

<3>Sep 26 11:22:29 node-4 kernel: [78373.817055] sd 2:0:0:0: rejecting I/O to offline device

5) On cinder node restore saveconfig.json
root@node-1:~# targetctl restore /etc/rtslib-fb-target/saveconfig.json
Restore failed, 1 errors:
Creating NetworkPortal object 192.168.1.1:3260 failed, skipped

root@node-1:~# netstat -ant |grep 3260
tcp 0 0 0.0.0.0:3260 0.0.0.0:* LISTEN

root@node-1:~# lsof -i:3260
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

tgtd 4508 root 8u IPv6 14758 0t0 TCP *:iscsi-target (LISTEN)

6) Stop and disable tgt service
7) On cinder node repeat restore saveconfig.json
root@node-1:~# targetctl restore /etc/rtslib-fb-target/saveconfig.json

8) Volume successfully reconnected
All next reboots of cinder node with disabled tgt service didn't reproduce the issue. Volume successfully reconnected without losing data in saveconfig.json.

Could you please provide additional information from the customer which will allow me to reproduce the issue on my test environment.
Thanks
