The following fields of partitionInfo are required to be set when the

* partition
sessionInfo: a complete info about the session the partition resides on
partitionIndex: partition index
partitionInfo: the partition info to be filled in
The function first tries to find a suitable partition module and to
delagate the work to that module. If no module could be found, for
