1 CHAPTER 1 Conf iguring the System Console This chapter explains what the system console is, describes the different ways of configuring it on your server , and helps you understand its relation to the system controller .
2 Sun Blade T6300 Server Module Administration Guide • April 2007 What the System Console Does The system console displays status and error messages generated by firmwar e-based tests during system startup. After running those tests, you can enter special commands that affect the f irmware and alter system behavior .
Chapter 1 Configuring the System Console 3 These constraints provide for secure access at the installation site. Using a TIP line enables you to use windowing and operating system features on the system making the connection to your server .
4 Sun Blade T6300 Server Module Administration Guide • April 2007 ▼ T o Use the Serial Port 1. Ensure that the serial port on your connecting device is set to the following parameters: ■ 9600 baud ■ 8 bits ■ No parity ■ 1 stop bit ■ No handshaking 2.
Chapter 1 Configuring the System Console 5 ▼ T o Access The System Console Through a T erminal Server 1. Complete the physical connection from the serial port to your terminal server . The serial port on the server is a data terminal equipment (DTE) port.
6 Sun Blade T6300 Server Module Administration Guide • April 2007 For example, for a server connected to port 10000 on a terminal server whose IP address is 192.
Chapter 1 Configuring the System Console 7 Modifying the /etc/remote File This procedur e might be necessary if you are accessing the server module using a TIP connection from a Sun system r unning an older version of the Solaris OS software.
8 Sun Blade T6300 Server Module Administration Guide • April 2007 Note – If you intend to use the Sun system’s serial port A rather than serial port B, edit this entry by replacing /dev/ttyb with /dev/ttya .
Chapter 1 Configuring the System Console 9 Switching Between the ALOM System Contr oller and the System Console If the system console is directed to the virtual-console device (its default configuration), the serial port and the network management port provide access to both the system console and the ALOM system controller (see FIGURE 1- 1 ).
10 Sun Blade T6300 Server Module Administration Guide • April 2007 The prompt displayed on the terminal or shell tool indicates which channel you are accessing: ■ The # or % prompt indicates that you ar e at the system console and that the Solaris OS is running.
Chapter 1 Configuring the System Console 11 Note – When you access the ALOM system controller for the first time and you issue an administrative command, you must create a password for the default username, admin, for subsequent access.
12 Sun Blade T6300 Server Module Administration Guide • April 2007 Reaching the sc> Pr ompt There ar e several ways to obtain the sc> prompt: ■ Y ou can log in directly to the ALOM system controller fr om a device connected to the serial port.
Chapter 1 Configuring the System Console 13 ■ When a serious hardwar e problem develops while the system is running, the operating system transitions smoothly to run level 0. ■ When you deliberately place the system under firmwar e control in or der to execute firmwar e-based commands.
14 Sun Blade T6300 Server Module Administration Guide • April 2007 Gracefully shutting down the system prevents data loss, enables you to warn users beforehand, and causes minimal disruption. Y ou can usually perform a graceful shutdown, provided the Solaris OS is running and the har dware has not experienced serious failure.
Chapter 1 Configuring the System Console 15 Using these commands results in the loss of all system coherence and state information. A manual system reset could corrupt the server ’s f ile systems, although the fsck command usually restor es them. Use this method only when nothing else works.
16 Sun Blade T6300 Server Module Administration Guide • April 2007 Caution – Forcing the server to the ok pr ompt suspends all application and operating system software. After you issue f irmware commands and run f irmware- based tests from the ok pr ompt, the system might not be able to resume where it left off.
Chapter 1 Configuring the System Console 17 System Console OpenBoot Conf iguration V ariable Settings Certain OpenBoot configuration variables contr ol from wher e system console input is taken and to where its output is dir ected. The table below shows how to set these variables in order to use the serial port and network management port.

Chapter 2 Managing RAS Features and System Firmware 23 ▼ T o Enable an Automatic Degraded Boot ● Set the switches by typing: Note – The default setting for auto-boot-on-error? is false . The system will not attempt a degraded boot unless you change this setting to true .
24 Sun Blade T6300 Server Module Administration Guide • April 2007 ■ If a fatal error is detected by POST or OpenBoot Diagnostics, the system does not boot regar dless of the settings of auto-boot? or auto-boot-on-error? .
Chapter 2 Managing RAS Features and System Firmware 25 ■ “Unconfiguring and Reconf iguring Devices” on page 27 ■ “T o Reconfigur e a Device Manually” on page 27 ■ “Obtaining Automatic System Recovery Information” on page 26 Enabling and Disabling Automatic System Recovery The ASR feature is not activated until you enable it.
26 Sun Blade T6300 Server Module Administration Guide • April 2007 ▼ T o Disable Automatic System Recovery 1. At the ok prompt, type: 2. T o cause the parameter changes to take effect, type: The system permanently stores the parameter change.
Chapter 2 Managing RAS Features and System Firmware 27 Unconf iguring and Reconfiguring Devices T o support a degraded boot capability , the ALOM firmware pr ovides the disablecomponent command, which enables you to unconfigure system devices manually .
28 Sun Blade T6300 Server Module Administration Guide • April 2007 Note – The device identifiers ar e not case-sensitive. Y ou can type them as uppercase or lowercase characters. Y ou can use the ALOM enablecomponent command to reconf igure any device that you previously unconf igured with the disablecomponent command.
