Re: Problem connecting iscsi lun: DID_TRANSPORT_DISRUPTED...
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!

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 -- You received this message because you are subscribed to the Google Groups open-iscsi group.

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!
