After discovery, how do I create sessions?

[Marc Singer <elf@xxxxxxxxx>]

I'm using the iscsi-tcp module in linux-2.6.15.6 and the
linux-iscsi-5.0.0.0.3rc6-36 user space tools.  The targets are on a
third-party iSCSI device used as an archiver and tape backup system.
I think that this device may be running BSD.

Discovery seems to work:

 # iscsiadm -m discovery --type sendtargets --portal=10.10.11.48
 [027515] 10.10.11.48:3260,1 eui.000b560000004285
 [027516] 10.10.11.48:3260,1 eui.000b560000004286

 # iscsiadm -m node
 [027515] 10.10.11.48:3260,1 eui.000b560000004285
 [027516] 10.10.11.48:3260,1 eui.000b560000004286

But I'm not able to initiate sessions to these devices.  Perhaps I
don't understand what I'm expected to do.

  # sudo iscsiadm -d8 -m node --record=027515 --login

  iscsiadm: iscsid reported error (9 - internal error)

I've run the daemon with debuging enabled, but it doesn't give me much
more information.

There are a couple of packets exchanged between the GNU/Linux machine
and the iSCSI target, but it's just a SYN, SYN/ACK, ACK triplet.

Pointers will be appreciated.

Cheers.
