Sun Microsystems V880, V890 manual Redirecting the console using OpenBoot mode

Using the remote console

Redirecting the console using OpenBoot mode

This procedure describes how to use the OpenBoot mode to redirect the local console to serial port A. Use the OpenBoot mode to redirect the remote console port when the Solaris method does not work. This typically occurs when the system will not boot.

Redirecting the local console to the remote console

To redirect control of the console port from the local console to a dialed-in remote console:

1.If the system is not already at the ok prompt, enter:

/usr/sbin/shutdown -y -i0 -g0

The system shuts down to the ok prompt.

!CAUTION:

If the shutdown command fails, press Stop+A simultaneously after the console banner is displayed, but before the operating system starts booting.

2.At the local console, enter the following commands to set the remote console configuration parameters:

setenv input-device ttya setenv output-device ttya setenv ttya-rts-dtr-off true setenv ttya-ignore-cd true setenv ttya-mode 9600,8,n,1,-

3.To verify the parameter changes, enter: printenv

The following message is displayed:

Parameter Name	Value	Default Value
output-device	ttya	screen
input-device	ttya	keyboard
.
.
.

4.If not already dialed in, dial in to the system from the remote console.

5.Log in to the system as root.
