Starting Up and Shutting Down the System
4.8 Shutting Down the System
Logical Name Description
SHUTDOWN$MINIMUM_MINUTES Defines the minimum number of minutes
you can specify as number of minutes
to shutdown. For example, if your users
require 30 minutes’ notice before a system
shutdown, define this logical name to be
30. This logical must be defined with the
/SYSTEM qualifier.
SHUTDOWN$QUEUE_MINUTES Defines the number of minutes remaining
before shutdown when queues are shut
down; must be defined with the /SYSTEM
qualifier. The default is 1 minute.
SHUTDOWN$TIME Defines the absolute time of the shutdown;
must be defined with the /SYSTEM qualifier.
SHUTDOWN$VERBOSE If defined to any string, specifies that the
shutdown command procedure is to list each
disk as it is dismounted.
If you plan to use an option every time you use SHUTDOWN.COM, define the
logical name in the site-specific startup command procedure SYLOGICALS.COM.
For more information, see Section 5.2.5.
Specifying a List of Nodes to Be Notified When the System Is Shutting Down
You can define the logical name SHUTDOWN$INFORM_NODES to be a
list of OpenVMS Cluster nodes that are notified when the system is shut
down. You must define SHUTDOWN$INFORM_NODES before executing
SYS$SYSTEM:SHUTDOWN.COM.
To define SHUTDOWN$INFORM_NODES, enter a command in the following
format:
DEFINE SHUTDOWN$INFORM_NODES "node-list"
where node-list specifies the list of nodes to be informed. For example:
$ DEFINE SHUTDOWN$INFORM_NODES "NODE1,NODE2,NODE3"
If you plan to inform the same nodes every time you shut down the system, add
the command to the site-specific startup command procedure SYLOGICALS.COM.
For more information, see Section 5.2.5.
If you define SHUTDOWN$INFORM_NODES, all member nodes included in
the list are notified when you execute SHUTDOWN.COM. Users on the node
that is being shut down are always notified, regardless of whether you define
SHUTDOWN$INFORM_NODES. If you omit the name of the node that is being
shut down from the list specified in the DEFINE command, SHUTDOWN.COM
automatically adds the name to the list.
The information in Table 4–3 indicates which nodes are notified at different
phases of the shutdown sequence, depending on whether SHUTDOWN$INFORM_
NODES is defined.
