Using the remote console
Overview
If your system does not boot, or the system cannot be diagnosed locally, remote support
personnel might want to redirect control of the console port from the local console to a
dialed-in remote console. Redirecting the console allows support personnel to do remote
maintenance as if they were at the local console. You can redirect the console using either:
● The Solaris operating system
● OpenBoot diagnostics
This section consists of the following procedures:
● Redirecting the console using Solaris on page 154. Use this procedure when the
system will boot up to the Solaris operating system.
● Redirecting the console using OpenBoot mode on page 157. Use this procedure when
the system will not boot up to the Solaris operating system.
Redirecting the console using Solaris
This procedure describes how to use the Solaris operating system to redirect the local
console to serial port B. This procedure is usually done from the remote console that has
dialed in to the system. Should you encounter any problems setting up the remote console,
see Remote console port problems
on page 186.

CAUTION:
CAUTION: Use this procedure only when absolutely necessary. If the console redirects
and the modem line drops, you may not be able to get back into the system.
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. Dial in from the remote console to the remote console modem, and log in as root.
