This morning I noticed a very interesting retweet by fellow vExpert Wil van Antwerpen from another vExpert: Richard Cardona (You may know him as rcardona2k on the VMTN Community Forums) about a neat little trick with the use of remote ESXi Shell (previous known as remote TSM).
For those of you who login remotely via SSH to the ESXi Shell (previously known as unsupported mode and Tech Support Mode) know that you can run the DCUI utility remotely by just typing “dcui”. The remote DCUI works just like it does using the direct console, with the exception of displaying the famous yellow and black screen that we are familiar with.
Richard came upon a neat little trick by setting the terminal type to “linux” from the default “xterm” that the yellow and black can be enabled when using the remote DCUI.
Before launching DCUI utility, you will need to run the following command on the ESXi Shell:
Next you will just type “dcui” and hit enter
Here is an example of running remote DCUI in color on ESXi 5
Here is an example of running remote DCUI in color on ESXi 4.1
Note: As you can see this is not a new trick in vSphere 5, but has been there since 4.x days but one big change with vSphere 5 is the full resolution of DCUI which many have complained about in the past.
If you are interested in other ways of customizing the DCUI, take a look at this blog post How to add a splash of color to ESXi DCUI Welcome Screen
Don’t forget to play some cool soundtrack music when using the DCUI 😉
