It could be caused by a scsi command timing out and abort tasks to try and clean it up failing, or a nop-out timing out, or the network error could have detected a error, or the target could have dropped the sesssion/connection. In your case it looks like a scsi command timed (by default this is 60 secs (see /sys/block/sdX/device/timeout)) out and this caused the scsi error handler to run. That failed, so we went to session level recovery and dropped the session. > iscsid: connect failed (113) > iscsid: connect failed (113) > iscsid: connect failed (113) The session/connection was dropped, and we tried to reconnect (we are at the stage just trying to do a socket connection). It failed with EHOSTUNREACH (No route to host). > kernel: session2: iscsi: session recovery timed out after 120 secs We tried to reconnect for node.session.timeo.replacement_timeout (see iscsi.conf for details) seconds, but could not so we failed the scsi error handler (this put the devices in the offline state) and that started failing commands. > kernel: sd 2:0:0:0: scsi: Device offlined - not ready after error > recovery So that explains what happened at the iscsi/scsi layers, but I am not sure it is helpful about the why it happened :( Normally when a scsi command times out and we cannot reconnect for 2 minutes, it is a driver bug or the something bad happened on the target or network. I am not sure what is in SLES, so if you could try the userspace tools and kernel modules from upstream: http://www.open-iscsi.org/bits/open-iscsi-2.0-865.15.tar.gz http://www.open-iscsi.org/bits/open-iscsi-2.0-868-test1.tar.gz it would help. Before installing the above, make sure you uninstall the SLES iscsi tools (do a "whereis iscsid" to make sure the old tools are removed before using the new ones), because I am not sure what is in SLES. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
