Enabling Tech Support Mode within VMware ESXi 4.1
Tech Support Mode within a VMware ESXi 4.1 host is a command-line interface for troubleshooting. The feature can be enabled via the vSphere client or via the console.
To enable via the console, log in as normal. Access the Troubleshooting Options selection from the main menu.
The Tech Support Mode should be disabled by default. A menu option is also available to place a limit on the amount of time the feature will remain active.
Save the changes. Use the key combination of Alt-F1 to enter the Tech Support Mode.
To return to the main console window, use the key combination of Alt-F2. Additional details on this topic can be found at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1017910.
