Starting Up and Shutting Down the System
4.8 Shutting Down the System
Qualifier Function
[NO]SPIN_DOWN_DISKS Spins down disks. The default is NO. You cannot
spin down the system disk.
[NO]INVOKE_SYSHUTDOWN Invokes the site-specific shutdown procedure. The
default is INVOKE_SYSHUTDOWN.
[NO]AUTOMATIC_REBOOT Reboots the system automatically when the
shutdown is complete. The default is NO.
[NO]REBOOT_CHECK Checks for basic operating system files and notifies
you if any are missing. The default is NO.
[NO]CLUSTER_SHUTDOWN Shuts down the entire OpenVMS Cluster system.
The default is NO.
[NO]REMOVE_NODE Removes the node from the active cluster quorum;
use this when you do not expect the shut-down
node to rejoin the cluster for an extended period.
The default is NO.
When you use this option, all locally attached disks
are dismounted clusterwide. Therefore, you must
shut down applications on other nodes that have
open files on the locally attached disks. Failure to
do so might cause mount verify timeout problems
as well as application problems.
[NO]SAVE_FEEDBACK Records feedback data from the system since it
was last booted and creates a new version of the
AUTOGEN feedback data file, which you can use
the next time you run AUTOGEN. The default is
NO.
Example
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> SHUTDOWN NODE/MINUTES_TO_SHUTDOWN=10/REBOOT_TIME="later" -
_SYSMAN> /REASON="DISK CORRUPTION PROBLEMS"/REBOOT_CHECK/SAVE_FEEDBACK
If you enter this command example on NODE21, it requests a shutdown on
NODE21 with:
• A message to users on all the cluster nodes, specifying:
SHUTDOWN message on node NODE21, from user SYSTEM at _NODE21$0PA0:
12:00:00:20. NODE21 will shut down in 10 minutes; back up later.
Please log off node NODE21. DISK CORRUPTION PROBLEMS
• A check for any missing operating system files and notification any are
missing
• Creation of a new AUTOGEN feedback data file based on the feedback data
collected since the system was last booted

Reference Manual.
4.8.5 Performing an Emergency Shutdown with the OPCCRASH.EXE Program
Ordinarily, you shut down the system using the orderly shutdown procedure
SHUTDOWN.COM. After SHUTDOWN.COM performs orderly housekeeping
tasks, it invokes the program SYS$SYSTEM:OPCCRASH.EXE to shut down the
system. OPCCRASH.EXE performs only the following minimal housekeeping
functions:
