Running DCLI Commands You can run DCLI commands as vCLI commands, from the vCenter Server Appliance shell, and from the command prompt of a vCenter Server Windows installation. Important Authentication options for DCLI commands differ from options for vCLI host management commands. ■ Overview of Running DCLI Commands ■ Running DCLI Commands ■ Input, Output, and Return Codes ■ Using DCLI with Variables ■ DCLI History File Important Users who run DCLI commands to monitor and manage vCenter services must have the appropriate privileges. ■ When you run DCLI commands included with vCLI, you must be a user who can authenticate to vCenter Single Sign-On and who is also authorized to perform the service, for example, manage vCenter tags. ■ When you run DCLI commands from the vCenter Server Appliance shell, DCLI allows you to run many commands without additional authentication. However, for management of certain services, you might be prompted for a user name and password.
