Hi list, I'm facing a similar problem as what has been discussed here in 2011 : https://groups.google.com/d/msg/open-iscsi/pQQ8_ernzgQ/7ZVkoDmY2qYJ but versions have since raised, so I don't know what to look at.
*TL;DR : * iscsiadm -m node -T iqn.1992-04.com.emc:cx.ckm00094900174.a2 -l ... ... -> sleeping there until I ctrl-c interrupt it. The only error msg I get is on the console : iscsi: invalid session 0 Specifying the SAN ip does not improve anything. *Long version :* We have a Dell PE R610 in 64bits with 4 NICs : - em1 + em2 are bonded and dedicated to the management on a specific VLAN - em3 and em4 are not bonded, and dedicated to the iSCSI specific VLAN ping -I from em3 and em4 towards our EMC Cx4-120 SAN is working, towards its two different IPs. And the ping from the SAN is also working. In /etc/sysctl.conf, I have : net.ipv4.conf.em3.arp_ignore = 1 net.ipv4.conf.em4.arp_ignore = 1 net.ipv4.conf.em3.arp_announce = 2 net.ipv4.conf.em4.arp_announce = 2 net.ipv4.conf.em3.rp_filter = 0 net.ipv4.conf.em4.rp_filter = 0 iptables and selinux are off.

They support offloading, but I'm not comfortable enough with that yet to play with it. So at present, I'd prefer just use a classical tcp transport. Iface scanning sounds good too : root@serv3:/var/lib/iscsi# iscsiadm -m iface default tcp,<empty>,<empty>,<empty>,<empty> iser iser,<empty>,<empty>,<empty>,<empty> bnx2i.f0:4d:a2:07:59:91 bnx2i,f0:4d:a2:07:59:91,<empty>,<empty>,<empty> bnx2i.00:00:00:00:00:00 bnx2i,00:00:00:00:00:00,<empty>,<empty>,<empty> bnx2i.f0:4d:a2:07:59:95 bnx2i,f0:4d:a2:07:59:95,<empty>,<empty>,<empty> bnx2i.f0:4d:a2:07:59:93 bnx2i,f0:4d:a2:07:59:93,<empty>,<empty>,<empty> Other informations : root@serv3:/var/lib/iscsi# rpm -qa|grep -i iscsi iscsi-initiator-utils-6.2.0.873-2.0.2.el6.i686 root@serv3:/var/lib/iscsi# iscsiuio -v iscsiuio: Version '0.7.6.1', Build Date: 'Wed May 29 14:08:11 PDT 2013' root@serv3:/var/lib/iscsi# uname -a Linux serv3 3.8.13-55.1.5.el6uek.x86_64 #2 SMP Wed Jan 28 17:03:28 PST 2015 x86_64 x86_64 x86_64 GNU/Linux I tried to disable em4, reboot, and try a connection from a single NIC (em3), but that did nothing better. I don't know if the fact that these NICs support offloading may disturb the simplest tcp transport way of connecting? I must admit I'm a little blocked here, as this is not the first server I'm connecting using iscsi, but as the pings are OK, what else could I check?
