I have been able to connect to this iSCSI target before but now I'm getting some weird errors, see attached vdsm.log but in short its about the following: Thread-161303::DEBUG::2013-03-07 09:54:14,401::task::568::TaskManager.Task::(_updateState) Task=`182a27fe-dfb0-4e68-965e-c77b61050da9`::moving from state init -> state preparing Thread-161303::INFO::2013-03-07 09:54:14,402::logUtils::41::dispatcher::(wrapper) Run and protect: discoverSendTargets(con={'connection': '192.168.4.234', 'password': '******', 'port': '3260', 'user': ''}, options=None) Thread-161303::DEBUG::2013-03-07 09:54:14,402::misc::84::Storage.Misc.excCmd::(<lambda>) '/usr/bin/sudo -n /sbin/iscsiadm -m discoverydb -t sendtargets -I default -p 192.168.4.234:3260 --op=new' (cwd None) Thread-161303::DEBUG::2013-03-07 09:54:14,428::misc::84::Storage.Misc.excCmd::(<lambda>) SUCCESS: <err> = ''; <rc> = 0 Thread-161303::DEBUG::2013-03-07 09:54:14,428::misc::84::Storage.Misc.excCmd::(<lambda>) '/usr/bin/sudo -n /sbin/iscsiadm -m discoverydb -t sendtargets -I default -p 192.168.4.234:3260 -n node.startup -v manual --op=update' (cwd None) Thread-161303::DEBUG::2013-03-07 09:54:14,452::misc::84::Storage.Misc.excCmd::(<lambda>) FAILED: <err> = 'iscsiadm: Cannot modify node.startup.

I have a wild guess but what interface is -I default referring to? I had more than one interface activated for this host but moved it to a cluster which didn't have the network definitions and removed the now invalid networks from the host. Just checked with tcpdump and the traffic is going through ovirtmgmt interface and the storage is responding. /var/lib/iscsi isn't filled with info, only sendtargets/target_ip_address/st_config Joop -- irc: jvandewege
