When remote access to the ESXi shell is enabled (SSH) or when the local ESXi shell is enabled, the vSphere client shows an alarm icon on the host in the inventory, and displays a warning on the hosts summary page. In this blog we look at how to prevent these from being displayed.
First of all let's see the effect of turning on the local ESXi shell and remote access. In the client you can clearly see the icon on the host and the warnings on the summary page shown.
To disable these from being shown, click on the hosts configuration tab, then select software-advanced settings.
The value that needs to be altered is within the UserVars category, and is at the bottom of the list. UserVars.SuppressShellWarning should be set to 0 to display the warnings and 1 to display them.
As soon as you have made the change to the variable the display will change, even though the ESXi shell or remote access to it is still enabled.
It should be noted that these warnings are there for a reason, it is bad practice to enable and leave these services on as it represents a major security risk.
