Automated Shutdown Procedure for Solaris/Irix

• This is for notes on automating a shutdown in preparation for a power outage or other outages.
• The general procedure goes like this:
  1. update motd a day or so before with the timing of the intended shutdown
  2. update cron with the shutdown command a day or so before
  3. if possible/necessary, send email to key users to let them know of the automated shutdown
• For Linux, see LinuxAutomatedShutdownProcedure

Solaris

1. ssh as root into the system to be shutdown
2. update the motd

# cd /etc
# co -l motd   (this may not work, in which case you can ignore it)
# vi motd
 - add something like:
  March 22, 2005
  ai0 will be shutdown at 4:30am Wednesday, March 23rd,
  for a planned power outage in DC.
# ci -u motd   (then this won't work either)

1. add the crontab entry:

 - set the VISUAL variable for your shell.  
   In bash/sh, it can be done like this:
     # bash
     # VISUAL=vi
     # export VISUAL
   In tcsh, it can be done like this:
     # tcsh
     # setenv VISUAL 'vi'
# crontab -e
 - add lines to the end like:
### Temporary additon to handle scheduled power outage (lfolland 2005/03/20)
0 3 23 3 * /usr/sbin/shutdown -y -i5 "Scheduled Power Outage March 23, 2005 at 3am"

• (save and exit - this automatically updates the crontab)
• Note in the above: "0 3 23 3 *" = 0 minutes, 3 hours (ie: 3am), 22nd day of any month, 3 - March, * any day of the week

Irix

• Mostly the same as above with the variation in the shutdown command

### Temporary additon to handle scheduled power outage (lfolland 2005/03/20)
0 3 23 3 * cd /; /etc/shutdown -y -g300 -i0 -p
