Changing hostname of SAP system


We are working on migrating our SAP systems to iASP's and virtual hostnames. I've done some research on changing the hostname of the SAP system in SM51 and the hostname of the gateway, but I haven't found anything on SAP systems that are running on the iSeries. We have multiple SAP systems installed on one LPAR and want each system to have it's own hostname in case we move that system to another LPAR. This way we won't have to change the hostname again and change all the connections from other systems that the system is connected to.

How do we change the hostname in SM51 and how to we change the default gateway hostname? Any ideas would be greatly appreciated.
