Here is a point of confusion that I've seen during ASM installs on HP-UX 11.23 using Securepath virtual devices. On one install we used one each of the underlying /dev/rdsk/xxxx paths from the autopath display to create the ASM disk groups. If you look at an autopath display, you will see the Device Path listed at the end of Lun WWN. That is what we used and it took us a while to get it straight.
The best practice is to ignore the individual devices in the path and use the secure virtual device file instead when creating your ASM disk groups. For example /hpap/dsk/hpap??
The secure virtual device takes away the confusion of the underlying devices which are just paths to the same device. Securepath handles the rest. Also, by using the secure virtual device file, the ASM disk group automatically shows up on all instances that use the same virtual device file.
