Using the Console Program
12.2 Entering Console Mode
• If the system is off, turn it on by pressing the 1 on the on/off switch on the
back of the system unit. The system will enter console mode unless it’s
been set to start the system software automatically. (See Section 12.3.2.)
12.3 Console Commands
This section explains some of the most frequently used console commands. For
more detailed information on console commands, see Appendix G.
Be sure to follow these rules when you type console commands:
• Type uppercase and lowercase letters exactly as they appear in command
lines. The system treats uppercase and lowercase letters as different input.
• Press Return after you type a command.
The following key combinations have an immediate effect in console mode:
• Ctrl-s freezes the screen display.
• Ctrl-q releases a frozen screen display.
12.3.1 The ? Command
Use the ? command to display a list of available console commands and their
formats.
Give the ? command by typing
?
and pressing Return.
12.3.2 The Boot Command
The boot command tells your system to start up the operating system software.
Give the command by typing boot and pressing Return.
If the boot path variable is set correctly, the system will find the drive on which
the workstation software is stored and start the software up. The boot path
variable tells the system where to look for the software.
To see how the boot path variable is currently set, type
printenv boot and
press Return.
You should see this display:
boot = 3/rz2/vmunix -a
Each part of this instruction gives you a different piece of information:
• The
3
tells the slot number. Slot 3 is the base system module.
•
rz2
describes the drive. The letters
rz
indicate a hard disk drive (yours
may be the RZ23L, RZ24, or RZ25, for instance), and the 2 is the SCSI ID
of that drive. (For information about SCSI IDs, see Section 6.3.)
