Unfortunately this change > did not find its way upstream yet ... Thanks for pointing this out. I found that this patch was submitted here over a year ago, but unfortunately was rejected: http://www.spinics.net/lists/linux-scsi/msg10289.html (I'm adding Cc's to the folks that posted to that thread) Christoph, would you be inclined to reconsider your position on this patch if it was changed so that the default behaviour would still be to remove devices after dev_loss_tmo expired? The current behaviour is causing troubles because of intermittent rport unavailability and the subsequent remove/readd actions way more often than I am permanently removing targets from my SAN, so for me being able to disable the automatic device removal would be a huge improvement for me (and I doubt I'm the only one that feels this way).
