Accessing Direct Console User Interface (DCUI) from an SSH session

Products

• VMware vSphere ESXi

Issue/Introduction

This article provides information on how to access Direct Console User Interface (DCUI) from an SSH session.

 

You must access the DCUI to troubleshoot issues and if there are no remote management tools available, such as iDRAC, iLO, or RSA, to access the ESXi host.

 

Impact/Risks:

Changing network settings using this command may make the host unusable and can necessitate a reboot to recover.

Environment

VMware vSphere ESXi (All Versions)

 

 

Resolution

Warning: Before accessing the DCUI from an SSH session, it is important to note that making any changes to network settings may lead to management issues through vCenter Server, vSphere Client or SSH. Networking changes should only be made through a console session (for example through iDRAC, iLO, KVM) to avoid host management issues. Changing network settings using this command may make the host unusable and can necessitate a reboot to recover.

• Run command dcui to access the DCUI from an SSH session:
• When viewing the system logs via View System Logs don't use number keys on the right of your keyboard as that will just result in you going back to the main screen, use the number keys along the top of your keyboard to make your selection of which logs to view 
• To exit the DCUI, press Ctrl+C.
• To clear the screen of the DCUI image run clear
