Me and many other technicians hate the limitation that the only supported way of migrating the Loadsource disk to a smaller LUN is save/restore IBMi OS. With the method described below, I was able to copy the Loadsource to the smaller disk, and it worked. Continue reading “IBMi – copy the loadsource to a smaller disk”
