Basicaly the simple answer is you need to take the package down, and modify the package control script, unless you are using mnodular packages in which case you need to edit and apply the modular package configuration file
Read the Managing Servioeguard manual for your version http://docs.hp.com/en/ha
This will redirect you to the new location, and sim,ply choose Serviceguard, then the manual for the revision you are using

Any resource modificatios to the package should be carried out with a downtime.

as me known, if it changed the pacakge IP, it means to re-configure the cluster!
