• The next step depends on whether a system is standalone,aserver,oraclient.
• If the system is standalone,
/sbin/rc
is executed to shut down subsystems, unmount file
systems, and perform other tasks to bring the system to run level 0.
• If the system is a server, the optional
-o argument is used to determine if all clients in the
cluster should also be rebooted. The default behavior (command-line parameter
-o is not
entered) is to reboot all clients using
/sbin/reboot; entering -o results in the server
only being rebooted and the clients being left alone. Then
/sbin/rc is executed to shut
down subsystems, unmount file systems, and perform other tasks to bring the system to run
level 0.
• If the system is a client,
/sbin/rc is executed to bring the system down to run-level 2, and
then
/sbin/reboot is executed. Shutdown to the single-user state is not an allowed
option for clients.
• The system is rebooted, halted, or put in the ready-to-reconfigure state by executing
/sbin/reboot if the -h or -r
or -R option was chosen. If the system was not a cluster client
and the system was being brought down to single-user state, a signal is sent to the
init process
to change states (see init (1M)).
DIAGNOSTICS
device busy
This is the most commonly encountered error diagnostic, and happens when a particular file system
could not be unmounted; see mount (1M).
user not allowed to shut down this system
User is not authorized to shut down the system. User and system must both be included in the
authorization file /etc/shutdown.allow
.
EXAMPLES
Immediately reboot the system and run HP-UX again:
shutdown -r 0
Halt the system in 5 minutes (300 seconds) with no interactive questions and answers:
shutdown -h -y 300
Go to run-level s in 10 minutes:
shutdown 600
Immediately shut down a partition so that it can be deleted:
shutdown -R -H 0
Reboot a partition in 5 minutes so that new cells that have been assigned to the partition become active:
shutdown -R 300
WARNINGS
The user name compared with the entry in the shutdown.allow file is obtained using getpwuid()
(see getpwent (3C)).
The hostname in
/etc/shutdown.allow is compared with the hostname obtained using gethost-
byname() (see gethostent (3N)).
shutdown must be executed from a directory on the root volume, such as the / directory.
The maximum broadcast message that can be sent is approximately 970 characters.
When executing
shutdown on an NFS diskless cluster server and the -o option is not entered, clients of
the server will be rebooted. No clients should be individually rebooted or shutdown while the cluster is
being shutdown.
If the
-R option is used in a virtual partition environment on a partitionable system, then the requested
reconfiguration will not take place until all the virtual partitions on that hard partition are shut down
and the virtual partition monitor is rebooted.
