Connect-CisServer

This cmdlet establishes a connection to the vSphere Automation SDK server specified by the -Server parameter.The connect and disconnect operations for a server are using a reference counting mechanism. Every server is identified by its connection string which contains server, user name, and port. If there is already an existing connection to the server for a specific user name and port, a new connection is not established. Instead, the cmdlet returns the object which represents the existing connection. The RefCount property of the object is incremented by one. Note that the returned object is the same as the one previously returned. Therefore, the RefCount of the previously returned object will be updated as well. When a server is disconnected, then its RefCount property is decreased by one. If this number becomes equal to zero, then the server is disconnected.PowerCLI for vSphere Automation SDK supports a list of default servers. When an operation is performed, if the target servers cannot be determined from the specified parameters, the cmdlet runs against the servers in the default server list. They are kept in a global variable called $DefaultCisServers. It is of an array type and its initial value is an empty array. When you connect to a server, the server is added at the beginning of the array, unless -NotDefault parameter is specified. When you disconnect from a server, the server is removed from the $DefaultCisServers variable. When all servers are removed from the variable its value is an empty array. You can modify the value of the $DefaultCisServers variable manually.
