Troubleshooting Remote Text Console issues
The following sections discuss items to be aware of when attempting to resolve Remote Text Console issues.
Unable to view the Linux installer in the text console
When installing Linux using the text console, the initial install screen might not display because the screen is
in graphics mode.
Solution: To correct this and proceed with the installation, do one the following:
• For most versions of Linux, enter linux text nofb. The characters you enter do not appear. After you enter
the command, the screen changes from graphics mode to text mode, displaying the screen.
• For SLES 10 and SLES 11, press F2 and (down arrow) from the text console. If done correctly, the text
mode is selected and the screen appears.
Unable to pass data through an SSH terminal
If you use an SSH terminal to access the text console, SSH might intercept keystroke data and not pass the
action to the text console. When this occurs, it appears as if the keystroke did not perform its function.
Solution: Disable any SSH terminal short-cuts.
Troubleshooting miscellaneous issues
The following sections discuss troubleshooting miscellaneous hardware or software issues.
Cookie sharing between browser instances and iLO
iLO uses browser session cookies in part to distinguish separate logins - each browser window displays as a
separate user login - while actually sharing the same active session with the iLO. These multiple logins can
confuse the browser. This confusion can appear as an iLO issue; however, this is a manifestation of typical
browser behavior.
Several processes can cause a browser to open additional windows. Browser windows opened from within
an open browser represent different aspects of the same program in memory. Consequently, each browser
window shares properties with the parent, including cookies.
Shared instances
When iLO opens another browser window, for example, Remote Console, or Help, this window shares the
same connection to iLO and the session cookie.
The iLO web server makes URL decisions based on each request received. For example, if a request does not
have access rights, it is redirected to the login page, regardless of the original request. Web server based
redirection, selecting File>New>Window or pressing the Ctrl+N keys, opens a duplicate instance of the
original browser.
