Using the remote console
If your system does not boot, or if 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 maintenance remotely
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 150. Use this procedure when the system
will boot up to the Solaris operating system.
Redirecting the console using OpenBoot mode on page 153. Use this procedure when the
system will not boot up to the Solaris operating system.
Redirecting the console using Solaris
The following procedure describes how to use the Solaris operating system to redirect the local
console to the serial port and 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 200 for troubleshooting procedures.
CAUTION:
!
CAUTION: Use the following 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.
2. At the remote console, enter:
/cms/install/bin/abcadm -r ttya
The following message is displayed at the remote console:
ttya is currently set to be incoming
