Starting Up and Shutting Down the System
4.8 Shutting Down the System
9. SHUTDOWN.COM dismounts all mounted volumes and, if you requested it,
spins down the disks. If you defined SHUTDOWN$VERBOSE, the procedure
lists each disk as it is dismounted.
The procedure does not spin down the system disk, nor does it dismount or
spin down the quorum disk (if one exists on your system).
10. SHUTDOWN.COM closes the operator log file.
11. SHUTDOWN.COM runs the program SYS$SYSTEM:OPCCRASH.EXE to
shut down the system.
12. If you requested an automatic reboot, the system reboots, provided you set
the necessary controls. You requested an automatic reboot if you answered
YES to the following question:
Should an automatic system reboot be performed [No]?
If you did not request an automatic reboot, a message similar to the following
one appears on the system console:
SYSTEM SHUTDOWN COMPLETE
On VAX systems, the following message is also displayed:
USE CONSOLE TO HALT SYSTEM
Halt the system after you see this message.

before DECnet is shut down; must be defined
with the /SYSTEM qualifier. The default is
6 minutes.
