To make kernel reread the new partition table, delete all used paths to the LUN. You can get the right device mapper device (dm-) from the output of multipath -ll. In this example it’s dm-4.

for d in /sys/block/dm-4/slaves/*; do echo “1” > $d/device/delete; done
and rediscover them.

echo “- – -” > /sys/class/scsi_host/host0/scan
echo “- – -” > /sys/class/scsi_host/host1/scan
multipath
