Hi Cesar,
The PRIORITY parameter does not determine which package will start first while starting the cluster. PRIORITY only determines the priority of the packages. So incase of a node failure which runs a package with highest priority, the package will be started on another node which runs a low priority package. To free up resources, the package with low priority might even be halted by serviceguard.
Now, for your requirement. If I get you correctly, you need the 3 packages to start in certain order. This order is determined by the order you specify while running "cmapplyconf" command. So you should halt the cluster & run below command.
# cmcheckconf -C
-P -P -P -v
If all goes fine.
# cmapplyconf -C -P -P -P -v
Then start the cluster & it should start packages in order, pkg1, pkg2 & pkg3.
# cmruncl -v
Hope this helps. (Please give points if it does)
