I am not sure which is the right way. Within the storage managment
software i can increase the size of the LUN. After rebooting the machine
the additional space is appended at the end of partitions and it is
marked as free. How can i now increase the LVM partition. Which
tool/programm i do need for this task?

The easy way would be to create a new partition to use that free space, then use pvcreate to make it a physical volume and then add it to the volume group. This would mean you'd have two physical volumes on the device belonging to the same volume group.
