To answer your question, if you follow the steps outlined in the Managing Serviceguard manual you will see that you first creat a VG and then share it using vgexport/vgimport.
Once that is done, you ensure the VG is activated on one node, and then you do the cmquerycl comand, which will detect a shared Vg and pick a physical disk to be the cluster lock disk, and it will fill this in automatiocally into the ascii file
