Stopping HP-UX
This section provides a brief overview of the process; for complete 
instructions, see Managing Systems and Workgroups. Additional 
information is contained in the V2500/V2600 SCA HP-UX System 
Guide
.
Typically, the system is shut down to:
• Put it in single-user state so that the system can be updated or to 
check file systems.
• Turn it off in order to perform a task such as installing a new disk 
drive.
CAUTION
Never stop the system by turning off the power. Stopping the system 
improperly can corrupt the file system. Use the 
shutdown
 or 
reboot 
commands. 
Shutdown considerations
Only the system administrator or a designated superuser can shut down 
the system.
The 
/sbin/shutdown
 command:
• Warns all users to log out of the system within a grace period you 
specify 
• Halts daemons
• Kills unauthorized processes
• Unmounts file systems
• Puts the system in single-user mode
• Writes the contents of the I/O buffers to a disk
CAUTION
Do not run 
shutdown
 from a remote system via 
rlogin
 if a network 
service is used. The shutdown process logs the user out prematurely and 
returns control to the console. Run 
shutdown
 from the sppconsole 
window on the SSP.
