Subject: [Users] Weird errors when trying to connect to an iSCSI target.
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:

Running the commands in a shell indeed gives the errors shown.
Which version of ovirt are you working with?
Sorry should have mentioned that. I'm on oVirt-3.2 stable on F18 engine
and hosts.
[root@host01 vdsm]# rpm -aq | grep vdsm
vdsm-python-4.10.3-9.fc18.x86_64
vdsm-cli-4.10.3-9.fc18.noarch
vdsm-xmlrpc-4.10.3-9.fc18.noarch
vdsm-4.10.3-9.fc18.x86_64
[root@host01 vdsm]# rpm -aq | grep iscsi
iscsi-initiator-utils-6.2.0.872-19.fc18.x86_64
[root@host01 vdsm]#
And in which shell did you try to run the command - vdsClient (vdsm's cli) or
regular command line?
plain bash.
[root@host01 vdsm]# /usr/bin/sudo -n /sbin/iscsiadm -m discoverydb -t
sendtargets -I default -p 192.168.4.234:3260 --op=new

[root@host01 vdsm]# /usr/bin/sudo -n /sbin/iscsiadm -m discoverydb -t
sendtargets -I default -p 192.168.4.234:3260 --op=delete
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
