You could use the CP SIGNAL SHUTDOWN command before you actually did the SHUTDOWN.

Reading the documentation in the virtualization cookbook for SLES10 and the vm CP COMMANDS manual; I have setup the following : 1. In each linux guest's /etc/inittab; I have changed the shutdown -r to shutdown -h 2. In my autolog1 exec I have placed the following command: CP SET SIGNAL SHUTDOWN 1200 ( To allow the guests 20 minutes to respond) Note: I have also entered the command manually When I issue the shutdown, vm shuts down before most if not all linux guests have responded or completed shutdown; always within a minute or two. As a result I end up with file corruption in some linux guests after vm is re-IPLed and the guests are brought back up. Is there a better way to accomplish a clean linux shutdown. Thank you, Bob Our SYSVINIT drop-in-replacement for a list-of-machines-in-autolog would do the trick. It may be overkill. Adam
