As I dont know whot/what you are using... I suppose I would start with a ioscan -funC disk look at the output and see if I find HW address that are similar passing by 2 different controlers...
So far you did not say what OS (version) you are using and architecture (yes there are still some PA-RISC out there...) nor if you are using esoteric software...
1? Is the system disc internal
2) Do you have already some VG configured
3) Are you using ( HP) LVM or other products...
4) What HBA do you have (Yes I had JNI HBA too...)
Those informations help you know...
