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:
!
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:
4. If not already dialed in, dial in to the system from the remote console.
5. Log in to the system as root.
