See this thread for my comments on the rpc message during the shutdown.

However, Sun supplies two versions of the shutdown command: /usr/sbin/shutdown and /usr/ucb/shutdown. The latter will understand "shutdown now" while the former will not.

The ucb version of shutdown is undocumented on Sun so I never use it on a Sun. But referring to my 4.3BSD manual, "shutdown now" will only take the system to single user mode. "shutdown -h now" will halt the box. And "shutdown -r now" will reboot. And all of this jibes with the HP-UX version of shutdown which is decended from the BSD version.

"When in Rome, do as the Romans..." I think you would be better off switching to /usr/sbin/shutdown on Sun boxes. First of all it is documented. (which won't help you until you install those man pages) And secondly, it is what most Sun people expect as you can see from Hassan2's comments. If you are going to continue using /usr/ucb/shutdown, at least mention this explicitly. A lot of Sun users don't even know about /usr/ucb/shutdown.

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
