Hi, multipath path tool use the external program, such as scsi_id in udev, to get the id of the lun. But how does it handle the lun remapping? For example, at first, thiere is a lun in array:lun1, it is mapped to host with lun id 11. On the host, I use the multipath program to generate a multipath device for this lun. Then I unmap lun1 and another lun: lun2 which is mapped to the host with the same lun id 11. In this situation, it seems that the multipath tool could not notice that there is a change of lun even after recreate the multipath device, is that true?
