you need to configure hearbeat ip in clcmlconf.ascii to build cluster not in /etc/hosts and /etc/rc.config.d/netconf files. Remove entries from those two files.

compile cluster ascii file using cmcheckconf and cmapplyconf. If you get any errors, you need to fix them during compilation.

you have to specify cluster lock device name (not volume group name) if you are using cluster lock.

Ex: /dev/dsk/c2t3d4 using as cluster lock disk

you should hav econtinued thi sdiscussion in your previous thread and NOT opened a new thread.

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
