VMware vSphere 4 Ctrl-Alt-Del how to disable

Posted by on November 11, 2009 in VMware, vSphere | 0 comments

Something to watch out for with the ESX 4 console. If you hit CTRL-ALT-DEL on ESX 4 console, the server will reboot even if there are running VMs and it doesn’t matter if the server is not in Maintenance Mode.

Follow these steps to disable this yourself:

1. Edit /etc/inittab. Any text editors will do- I like nano but vi works just as well.
2. Search for “CTRL-ALT-DELETE” or “ctrlaltdel”
3. Comment out the line “ca::ctrlaltdel:/sbin/shutdown -t3 -r now” with a # symbol.

It should look like:


# ca::ctrlaltdel:/sbin/shutdown -t3 -r now

4. Save and exit the file.
5. To make this take effect without a reboot, run the command:

init q
