The root cause: When scsi_dh_activate returns SCSI_DH_NOSYS the activate_complete callback is not called and the error is not propagated to the multipath layer. A similar situation occurs when the handler is in the process of being deleted (e.g. the SCSI device is in a SDEV_CANCEL or SDEV_DEL state). Attached is the SCSI H/W handler part of this patch.
