9. Text Console Redirection (SOL, Serial Over LAN)

Figure 9-1

On the Text Console tab of the IPMI View management session in the Viewing Window (as shown in

Figure 9-1), there is a function that allows you to remotely control the managed system from a text mode

console. Click the Start button to start the text console redirection. During control, click the ReSynch

button to synchronize the text console with the managed system if you think the screen is not shown

properly. Click the Stop button to stop the text console.

• BMC for IPMI 1.5

Console Redirection is not a function in the IPMI specification V1.5. Supermicro provides this

useful function for a manager to control the managed system remotely. When a managed system is

booting up and in the POST routine and no other software application can give you control to

redirect the console, IPMI View offers this valuable function. Console Redirection will dump a

managed system’s screen to IPMI View and send the key codes you entered in the managed system.

When a managed system switches its video mode from Text Mode to Graphics Mode, a terminate

notice will be sent to IPMI View to terminate the console redirection. Text Console Redirection

only works for text mode.

Important: Console Redirection puts a very heavy load on a managed system. It will dump the

whole screen to the manager’s system and slow down the managed system significantly. We suggest

you use this function only when you need to get special control and cannot achieve it any other way.

For other applications, a proper console redirection software application (pcAnywhere, Symantec

Corporation) or a remote login protocol (telnet) is suggested. When you finish your remote

operation, click Stop to terminate console redirection to take the load off the managed system.

• BMC for IPMI 2.0

IPMI specification V2.0 defines Serial Over LAN (SOL) to support Text Console Redirection. This

implementation performs better than the one we implemented for IPMI 1.5. The Text mode console

remains working on Windows 2003, even when the OS is running. To support Text Console
