Managing Default Server Connections in PowerCLI
By default, PowerCLI cmdlets run on the vCenter Server or VMware Cloud Director systems you are connected to, if no target servers can be determined from the provided parameters. Use the $DefaultVIServers and $DefaultCIServers variables to manage the default server connections.
When you connect to a vCenter Server system by using Connect-VIServer, the server connection is stored in the $DefaultVIServers array variable. This variable contains all connected servers for the current PowerCLI session. To remove a server from the $DefaultVIServers variable, you can either use Disconnect-VIServer to close all active connections to this server, or modify the value of $DefaultVIServers manually.
When you connect to a VMware Cloud Director system by using Connect-CIServer, the server connection is stored in the $DefaultCIServers array variable. This variable contains all connected servers for the current session. To remove a server from the $DefaultCIServers variable, you can either use Disconnect-CIServer to close all active connections to this server, or modify the value of $DefaultCIServers manually.
