How to troubleshoot the Sun x86 Servers ILOM 'remote console' when it appears inoperative.

Solution

To troubleshoot remote console redirection it is usually helpful to start the /SP/console and the VGA console (via web GUI remote console redirection) both at the same time and watch both console screens during POST and up through the OS launch process.

1. Start with the host off.

2. Next, ssh to the SP and start the /SP/console

ssh xxx.xxx.xxx.xxx -l root

Using username "root".
Using keyboard-interactive authentication.

->

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y

3. Now, start a browser session to the SP and click on either "Launch Redirection" or "Launch Remote Console". The example below is ILOM 3.0.

4. When both console screens are active, power on the host and wait for the host to start POST.

From both screens, you should see the system begin POST and if necessary you can interact with the system BIOS from either one.

After POST, you will see the beginning stage of OS launch. For example, grub.

Very soon after the OS launches one of the screens usually will stop working depending on the console output setting of your OS.

Note: In the example below, 'ttya' is used for the console setting. While 'ttya' is the usual setting for almost platforms but it is not always the correct setting. One known exception is the SunBlade 6250 which uses 'ttyb' instead of 'ttya'. Refer to the ILOM documentation to verify the correct console setting.

For example with Solaris, the eeprom setting dictates which console is active.

# eeprom | grep console
console=ttya

If console = 'ttya' then the serial console (/SP/console) will be active.
This is usually the case if the OS was originally installed or recently re-installed over the serial (non-GUI) port.

# eeprom | grep console
console=text

If console = 'text' then the VGA port (i.e., the redirected remote console) will be active.
This is usually the case if the OS was originally installed recently re-installed via the GUI interface.

If you change the eeprom console setting, an OS reboot will be needed.
