You can still statically connect though, which I recommend > for loopback connections. Yep, iptables doesn't run on that machine, the service is disabled. And I'm just using the one IP address on that machine. Here's my /var/lib/iscsi/ifaces/iface0 file: iface.transport_name = tcp iface.hwaddress = 00:1D:92:B4:50:6E Is the transport_name for loopback still tcp? The discovery appears to work properly: [root at lh6 iscsi]# iscsiadm -m discovery -t st -p 10.200.1.6:3260 -I iface0 -P 1 Target: iqn.2009-10.net.linush:storage.disk1.sys1.asmdg Portal: 10.200.1.6:3260,1 Iface Name: iface0 I found a way to make the entry in /var/lib/iscsi/static which is just a symbolic link back to the entry in /var/lib/iscsi/nodes, but you must be seeing different documentation because I don't see any thing that talks about logging in using the static entry. At any rate, I run this command and get the output as shown: [root at lh6 iscsi]# iscsiadm -m node -T iqn.2009-10.net.linush:storage.disk1.sys1.asmdg -p 10.200.1.6:3260 -l Logging in to [iface: iface0, target: iqn.2009-10.net.linush:storage.disk1.sys1.asmdg, portal: 10.200.1.6,3260] iscsiadm: Could not login to [iface: iface0, target: iqn.2009-10.net.linush:storage.disk1.sys1.asmdg, portal: 10.200.1.6,3260]: iscsiadm: initiator reported error (8 - connection timed out) And here's the node: [root at lh6 iscsi]# cat nodes/iqn.2009-10.net.linush\:storage.disk1.sys1.asmdg/10.200.1.6\,3260\,1/iface0 # BEGIN RECORD 2.0-868 node.name = iqn.2009-10.net.linush:storage.disk1.sys1.asmdg node.tpgt = 1 node.startup = manual iface.hwaddress = 00:1D:92:B4:50:6E iface.iscsi_ifacename = iface0 iface.net_ifacename = default iface.transport_name = tcp node.discovery_port = 0 node.discovery_type = static node.session.initial_cmdsn = 0 node.session.initial_login_retry_max = 4 node.session.cmds_max = 128 node.session.queue_depth = 32 node.session.auth.authmethod = None node.session.timeo.replacement_timeout = 120 node.session.err_timeo.abort_timeout = 15 node.session.err_timeo.lu_reset_timeout = 30 node.session.err_timeo.host_reset_timeout = 60 node.session.iscsi.FastAbort = Yes node.session.iscsi.InitialR2T = No node.session.iscsi.ImmediateData = Yes node.session.iscsi.FirstBurstLength = 262144 node.session.iscsi.MaxBurstLength = 16776192 node.session.iscsi.DefaultTime2Retain = 0 node.session.iscsi.DefaultTime2Wait = 2 node.session.iscsi.MaxConnections = 1 node.session.iscsi.MaxOutstandingR2T = 1 node.session.iscsi.ERL = 0 node.conn[0].address = 10.200.1.6 node.conn[0].port = 3260 node.conn[0].startup = manual node.conn[0].tcp.window_size = 524288 node.conn[0].tcp.type_of_service = 0 node.conn[0].timeo.logout_timeout = 15 node.conn[0].timeo.login_timeout = 15 node.conn[0].timeo.auth_timeout = 45 node.conn[0].timeo.noop_out_interval = 5 node.conn[0].timeo.noop_out_timeout = 5 node.conn[0].iscsi.MaxRecvDataSegmentLength = 131072 node.conn[0].iscsi.HeaderDigest = None,CRC32C node.conn[0].iscsi.IFMarker = No node.conn[0].iscsi.OFMarker = No # END RECORD >From ifconfig: eth2 Link encap:Ethernet HWaddr 00:1D:92:B4:50:6E inet addr:10.200.1.6 Bcast:10.200.1.255 Mask:255.255.255.0
