Offload is dependent on the hardware, something that I
don't have<br>
access to. With you assistance, we can improve the state
in Debian.<br>

<div>I count on it too :) Now all of hardware of this type
that I have access to is used in production environment.
It is quite easy to migrate services somewhere else from
time to time. But for now only tests without upgrading
system to any other than stable are possible. (upgrading
and downgrading iscsi-tools is okej for me)<br>

That's fine. We still can use your current running systems to get
some idea.<br>

Any clues on what interface was it configured here?<br>

Unfortunately I do not know what interface name iscsid is
using to communicate. I suppose it might
be bnx2i.00:10:18:e6:c3:55 and it is failing because it
is not available in system as regular interface (it is not
listed by ifconfig).<br>

iSCSI works over TCP/IP. Unless specified otherwise, it will use
your Operating System's Default Route Interface for the network you
are trying to discover to. What does your routing table look like?<br>
<br>
<br>
Also, the README shipped with the open-iscsi package talks about
Offload configuration in section 5.1.2. To quote it...<br>
<br>
<blockquote><font color="#3333ff">5.1.2 Setting up a iface for a
iSCSI offload card<br>
=================================================<br>
<br>
This section describes how to setup ifaces for use with Chelsio,
Broadcom and<br>
QLogic cards.<br>
<br>
By default, iscsiadm will create a iface for each Broadcom,
QLogic and Chelsio<br>
port. The iface name will be of the form:<br>
<br>
$transport/driver_name.$MAC_ADDRESS<br>
<br>
Running:<br>
<br>
# iscsiadm -m iface<br>
default
tcp,<empty>,<empty>,<empty>,<empty><br>
iser
iser,<empty>,<empty>,<empty>,<empty><br>
cxgb3i.00:07:43:05:97:07
cxgb3i,00:07:43:05:97:07,<empty>,<empty>,<empty><br>
qla4xxx.00:0e:1e:04:8b:2e
qla4xxx,00:0e:1e:04:8b:2e,<empty>,<empty>,<empty><br>
<br>
<br>
Will report iface configurations that are setup in
/etc/iscsi/ifaces.<br>
The format is:<br>
<br>
iface_name
transport_name,hwaddress,ipaddress,net_ifacename,initiatorname<br>
<br>
iface_name: name of iface<br>
transport_name: name of driver<br>
hwaddress: MAC address<br>
ipaddress: IP address to use for this port<br>
net_iface_name: Net_ifacename will be <empty>
because change between<br>
reboots. It is used for software iSCSI's vlan or alias binding.</font><br>
<br>
</blockquote>
Now, you could relate it to what you have, and see if your settings
are complete. But please do share your routing table too.<br>

Is this supposed to remain empty?<br>

<div>It might be filled net_interface OR hwaddress. You
can't have them both. But as I see now when I was
preparing configuration for bug reporting purposes I did a
mistake. hwaddress should be 00:10:18:e6:c3:54. I a few
days on testing in on many cases and left this kind of bug
in bug report... such a shame :/<br>

Is iscsiuio part of the upstream open-iscsi source
repository ? And<br>
then, like you've said, we'll have to assess the
licensing/copyright<br>
details.<br>
<br>
Best to start would be to check it in Fedora too. Fedora
claims to be<br>
GPL. So if those patches are shipped there, then we can
spend some time<br>
to study its possibility of getting included in Debian.<br>

<div>Fedora do have the this package. There is iscsiuio

That looks like a separate package. I will see if I can get some
time this or the next week to explore it. Maybe I might package it,
but like I said, without access to hardware, I will not be doing a
good job in maintaining its quality.<br>
