From: Rob Evers<revers@xxxxxxxxxx> When alua targets are transitioning, the scsi midlayer retry mechanism continuously retries the scsi commands that are returning with not ready transitioning status. The target is not capable of handling the commands for time on the order of several seconds during these transistions. This patch delays the device queue for 2 seconds, which is in the same order of aas transition time. Also, handle all other cases where ADD_TO_MLQUEUE_DELAY could be returned instead of ADD_TO_MLQUEUE as if ADD_TO_MLQUEUE were being returned. Problem found by array partner testing change MLQUEUE_DEV_DLY_RTY to MLQUEUE_DELAYED_RETRY
Hi James, I noticed this didn't get included yet. If you are planning to include this, please hold off. I misunderstood the testing status initially and we need to collect more information. It may take some time.
