Note: No ‘break’ commands will be sent on the serial Ports during a SCS system
reboot. Your servers will not be affected.
Thinklogical ® SCS systems are “break-safe”, meaning that they will not send a ‘break’ command
(unless user initiated) or other data on the serial ports connected to your servers. An unwanted
‘break’ could cause problems with your server.
6.1.3 poweroff
If you want to turn the SCS off, you must first run the poweroff command.
!
Note: No ‘break’ commands will be sent on the serial Ports during a SCS system
poweroff cycle. Your servers will not be adversely affected.
poweroff may be run at any time. The save command is run as part of the poweroff
process. Once you have entered the poweroff command, the operating system will shut down
and the SCS will cease operating. The front panel display will show OK to Power Off . You
may now turn the power switch off.
The only way to recover from a poweroff command is to turn the system power off and then
turn the power back on.
6.1.4 Other Linux Commands
The following Linux commands, among others, will be used with the SCS systems.
logout
Use logout to quit your session with the system.
man
Use man <command name> to search for a help file (online manual pages) or descriptive
information for that Linux / UNIX command.
Three general man pages are available for Thinklogical commands and files:
1. lsi.1 for user commands
2. lsi.8 for system commands
3 . lsi.5 for Thinklogical file descriptions
passwd
The root user should change the default root password as soon as possible to prevent
unauthorized access.
To change the default root password, type passwd (all lower case) at
the root login prompt.
scp
Use scp for secure copy using ssh (secure shell host) between two hosts. The process is
encrypted and inherently secure. Refer to the man pages for scp for a description and any
command options.
