Description Libor Zoubek 2013-09-13 22:21:42 UTC 
Description of problem: vdsm is not able to parse response from iscsadm discovery when target portal exports at least one target on IPv6


Version-Release number of selected component (if applicable):
RHEVH 6.4 (20130815.0.el6_4)

How reproducible: always


Steps to Reproduce:
1. setup tgtd on some target host to export something on IPv6
2. select Host in UI and try to discover on your target

This is what returns

iscsiadm -m discoverydb -t sendtargets -I default -p 192.168.130.101:3260 --discover

192.168.130.101:3260,1 iqn.1992-01.com.lsi:2365.60080e50002d65400000000051ac6bde

Actual results:
RHEV-M UI claims no targets have been discovered, this appears in vdsm.log

Thread-11201::ERROR::2013-09-13 22:18:06,059::task::850::TaskManager.Task::(_setError) Task=`57269ae6-ed0c-45ed-a518-f063a757a4db`::Unexpected error

Expected results: targets are correctly detected
