The command "cluster shutdown -g0 -y" shuts down the entire cluster in an orderly fashion.
“cluster shutdown” performs the following actions when it shuts down the cluster:
- Changes all functioning resource groups on the cluster to an offline state
- Unmount all file systems
- Shuts down all active device services
- Runs /usr/sbin/init 0 on all nodes
Now, the only difference between Sparc and x86/64 platform is in the last step when /usr/sbin/init 0 is executed.
On Sparc platform, all nodes will drop to "OK" prompt. On x86/64 platform, all nodes will display "Press any key to continue".
By the way, you'll be surprised how extensively is Sun Cluster being used in the healthcare/maritime/defense industry in S'pore.
