If I have 1 volume setup (/dev/test_vg/testlv1) and mounted on say, /mnt. The disk is connected via scsi host channel 0, scsi id 4, and lun 0. If i umount /mnt, move the scsi disk to host channel 1, Then run rescan-scsi-bus.sh 1, it should scan the scsi bus on host channel 1, then find the scsi disk. is there a way to make lvm see the new disk in a way that is mountable? I have done the previous, but i see in /proc/lvm/global, that each VG is associated with PV devices (/dev/sda1, etc). Is there a way that lvm can rescan and reassociate VGs to new PV devices? (as in the disk on the host channel 1 is added in as /dev/sdd).. If i reboot, this is no problem to register things, but I am wonder if it is possible to do the task without a reboot..
