establish a connection to either an ESXi host or a vCenter Server.


Connect to ESXi host using integrated authentication
Connect-VIServer 192.168.10.1

# Connect to ESXi host using credentials passed on from the command line.
Connect-VIServer 192.168.16.113 -User root -Password Notapassword

# Connect to a host or vCenter Server using -menu parameter to 
# select an entry from a history list of previously established connections
Connect-VIServer -menu

How do I retrieve a list of connections currently in use?
There’s a variable called DefaultVIServers which keeps a list of connections established during a current session. We can display the contents by simply calling the variable as follows;

$DefaultVIServers

Display currently established ESXi or vCenter Server connections
Display the list of currently established ESXi or vCenter Server connections

# disconnect from an ESXi host or vCenter Server
Disconnect-VIServer

# Drop all established connections
Disconnect-VIServer -Server * -Force

# Drop a specific connection using the $DefaultVIServers variable. 
# Note that the variable in reality is an array, 
# with [0] represents first entry [1] the second
# parameter to suppress confirmation.
-Confirm:$false
Disconnect-VIServer -Server $DefaultVIServer[0] -Confirm:$false

$ Drop connection by IP address / ESXi hostname / vCenter Server.
