Re: Problem connecting iscsi lun: DID_TRANSPORT_DISRUPTED...

2011-01-18 Thread Pierre-Yves Langlois
Hi Mike,

I made more test to debug my setup. My original setup uses a bond on 2 nic.
If I only use one nic to connect to the SAN, everything works fine. The
problem occurs when I use the bond... Does iscsi need a special
configuration with bond or is it transparent to him?

Thanks!

 Do I look at the right place?


 Did you do the echo, then relogin to the target?


 echo 1  /sys/module/libiscsi/parameters/debug_libiscsi_eh
 iscsiadm -m node -u
 iscsiadm -m node -l

It is transparent. iscsi_tcp runs from a high level. It basically just 
opens a socket like other network apps then it does send()/recv() to 
send/recv IO (recv is a little more complicated).


If you are using iscsi iface hwardare/session binding with iscsi_tcp 
then it is more complicated. I am not sure if that combo would work.





Thanks!
