GRF 400/1600 Getting Started - 1.4 Update 2
Cabling and Verifying Media Cards
Rebooting the system
Rebooting the system
You shut down the system depending upon how you connect to the GRF. When you are using
the VT 100 terminal (or laptop), use the grms command. When you are have logged into the
GRF from a remote workstation on the administrative Ethernet, use the shutdown command.
Rebooting from the VT 100 terminal - grms
Use the grms command to halt, reboot, or shut down the system from the UNIX prompt.
grms performs the same function as shutdown but does not require the user to be logged in as
root
. However, it can only be used from the control board VT-100 terminal. Use shutdown -r
now if you manage the GRF from a remote terminal.
The grms command performs an orderly shutdown, saving memory and allowing any transfers
to complete. When the reboot option is specified, the system is rebooted and all media cards
are reset.
1
Attach a keyboard to the VT-100 terminal and log in. You do not have to be
root
.
2
Enter the
grms
command with one of its options:
With the -h option, grms halts the system (like shutdown -h now).
With the -r option, grms performs an orderly reboot of the system (like shutdown -r now).
With the -s option, grms performs an orderly shutdown of the system. To restart, enter the
reboot command.
Rebooting from a remote workstation - shutdown
If you manage the GRF from a remote station, use the shutdown command to reset the system
from a UNIX prompt.
The shutdown command performs an orderly shutdown, saving memory and allowing any
transfers to complete. With the -r and now options, the command performs an orderly reset of
the system. It also issues a special command to the control board to restart the GRF
immediately.
1
Log in as
root
.
2
Enter the shutdown
-r
now command.
After the shutdown completes, the prompt appears and you can log in again.
