I think what Erez was saying, besides use iscsi_discovery, was that you
should set this to None and it should work. In the /var/log/messages do
you also see:
log_error("transport '%s' does not support "
"HeaderDigest != None", t->name);
The iser driver does not support digests so we do not even try to
negotiate. We do not even try to login because the driver said it does
not support them. I guess a better option would be to just drop the user
requested param and do None for the user - will do that later.
But you h

We used to not really support distro kernels, because they have so much different stuff that I cannot keep track of what hacks need to go in what. So you can just not use that kernel which looks like RHEL 5, or use the code in git. I just merged a patch that is supposed to fix that.

I decided to go on ahead and update to these latest OpeniSCSI bits, but am having build issues.

Re: iSER login process
Having some issues with SendTargets, so I've gone with this first example (static config), and am seeing some issues with the modify. I am running the OpeniSCSI that comes with OFED 1.3.1. Should I move to another release, maybe? /* create, no error */ # iscsiadm -m node -T iqn.1986-03.com.sun:02:aff22998-3466-4bf4- ee3c-958fd4b5d346 -p 10.8.0.6:3260 -o new New iSCSI node [tcp:[hw=default,ip=,net_if=default,iscsi_if=default] 10.8.0.6,3260,-1 iqn.1986-03.com.sun:02:aff22998-3466-4bf4- ee3c-958fd4b5d346] added /* dump the config */ # iscsiadm -m node -T iqn.1986-03.com.sun:02:aff22998-3466-4bf4- ee3c-958fd4b5d346 -p 10.8.0.6:3260 node.name = iqn.1986-03.com.sun:02:aff22998-3466-4bf4-ee3c-958fd4b5d346 node.tpgt = -1 node.startup = manual iface.hwaddress = default iface.iscsi_ifacename = default iface.net_ifacename = default iface.transport_name = tcp node.discovery_address = 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.auth.username = node.session.auth.password = node.session.auth.username_in = node.session.auth.password_in = node.session.timeo.replacement_timeout = 120 node.session.err_timeo.abort_timeout = 10 node.session.err_timeo.reset_timeout = 30 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 = 10.8.0.6 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.active_timeout = 5 node.conn[0].timeo.idle_timeout = 60 node.conn[0].timeo.ping_timeout = 5 node.conn[0].timeo.noop_out_interval = 10 node.conn[0].timeo.noop_out_timeout = 15 node.conn[0].iscsi.MaxRecvDataSegmentLength = 131072 node.conn[0].iscsi.HeaderDigest = None,CRC32C node.conn[0].iscsi.DataDigest = None node.conn[0].iscsi.IFMarker = No node.conn[0].iscsi.OFMarker = No /* now, modify the transport (tcp to iser) */ # iscsiadm -m node -T iqn.1986-03.com.sun:02:aff22998-3466-4bf4- ee3c-958fd4b5d346 -p 10.8.0.6:3260 -o update -n iface.transport_name - v iser /* no error, dump the config */ # iscsiadm -m node -T iqn.1986-03.com.sun:02:aff22998-3466-4bf4- ee3c-958fd4b5d346 -p 10.8.0.6:3260 iscsiadm: iface iter could not stat /etc/iscsi/nodes/iqn. 1986-03.com.sun:02:aff22998-3466-4bf4-ee3c-958fd4b5d346/10.8.0.6,3260. iscsiadm: Could not execute operation on all records.

Re: iSER login process
This is, if not exactly what I need, at least a lot of new info for me. I haven't seen any of this in any of the Wiki's, READMEs or other sundry documents out there that describe configuring iSER. Thanks very much, I'll see if this gets me going. Best Jesse On Aug 17, 2008, at 1:40 PM, Mike Christie wrote: > > Jesse Butler wrote: >> >> (This could be a duplicate post, not sure.
