Troubleshooting

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 152. Use this procedure when the system will boot up to the Solaris operating system.

Redirecting the console using OpenBoot mode on page 155. 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:

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
