Starting Up and Shutting Down the System
4.8 Shutting Down the System
Enter an integer. If you have defined the system logical name
SHUTDOWN$MINIMUM_MINUTES, its integer value is the minimum
value that you can enter. For example, if the logical name is defined as 10,
you must specify at least 10 minutes to final shutdown or an error message
is returned. If you do not enter a value, SHUTDOWN.COM uses the logical
name value.
Caution
The default is 0 minutes. If you have not defined the logical name
SHUTDOWN$MINIMUM_MINUTES, and you do not enter a value,
the system will be shut down immediately after you answer the last
question.
3. The system displays the following question:
Reason for shutdown [standalone]:
Enter a one-line reason for shutting down the system. For example, ‘‘Monthly
preventive maintenance.’’
4. The system displays the following question:
Do you want to spin down the disk volumes [No]?
Enter YES or NO (Y or N). Note, however, that you cannot spin down the
system disk. Also, many disks, particularly SCSI disks, do not spin down in
response to this option.
5. The system displays the following question:
Do you want to invoke the site-specific shutdown procedure [Yes]?
If you have entered site-specific commands in SYSHUTDWN.COM, press
Return to accept the default answer, YES. For more information, see
Section 4.8.3.2.
6. The system displays the following question:
Should an automatic system reboot be performed [No]?
By default, the system does not automatically reboot. However, if you respond
YES, the system attempts to reboot automatically when the shutdown is
complete. For example, you would specify YES if you are rebooting the
system after modifying values for nondynamic system parameters with
SYSMAN or SYSGEN. (When you change nondynamic system parameters,
you must reboot the system for the new values to take effect.)
7. The system displays a question similar to the following one:
When will the system be rebooted [later]?
If you entered YES in step 6, the default answer to this question is ‘‘[shortly
via automatic reboot]’’.
Press Return to take the default, or enter the expected reboot time in the
format you want users to see. For example, you could specify IMMEDIATELY,
or IN 10 MINUTES, or a time such as 2 P.M. or 14:00. If you do not know
when the system will be available again, press Return to specify ‘‘later’’ as the
time when the system will reboot.
