Comment 3 Bruno Goncalves 2015-08-12 09:28:35 EDT
It is not only on aarch64, I've also reproduced it on 7.2 Alpha on x86_64

# iscsiadm -m discovery -I default -p ::1 -t st
iscsiadm: Cannot resolve host [::1]. getaddrinfo error: [Name or service not known]

iscsiadm: cannot resolve [::1]
iscsiadm: failed to add default portal, ignoring target iqn.2009-10.com.redhat:storage-1
iscsiadm: failed to add target record
iscsiadm: No portals found

# uname -r
3.10.0-302.el7.x86_64

# targetcli-2.1.fb41-2.el7.noarch
Comment 4 Bruno Goncalves 2015-08-12 09:52:14 EDT
Setting it as Regression as it works well on kernel -300 and fails on -301, probably due BZ#1136558
Comment 7 Andy Grover 2015-08-18 12:01:08 EDT
Bruno or Martin, can you please attach your target config, '/etc/target/saveconfig.json'? Thanks.
Comment 8 Andy Grover 2015-08-18 12:05:01 EDT
netstat -an output would also be great.
