HP-UX System Administrator's Guide: Routine Management Tasks

1. Notify anyone who is likely to be affected by the shutdown of your system. You
can do this by:
• e-mail
• the wall command (see wall(1M)) — only notifies users of your system, not
users of other systems that are likely to be affected by a shutdown of your
system
• calling them on the phone, or speaking to them in person
However you do it, the critical thing is to notify them as far in advance as possible
of your planned shutdown. If you notify them far in advance of the planned
shutdown, it is also a good idea to give them a reminder as the time for the
shutdown approaches.
