This article is another part and related to this VMware PowerCLI Connect-VIServer Object reference not set to an instance of an object. The resolution used in the earlier blog is applied here in this article.
The problem description is, I connected to my vCenter server after I tried to connect ESXi server with esxcli command set but sub command elements where blank empty. I wanted to install software vib using esxcli but since sub namespace commands where not available, I was not able to perform any command. This issue is due to older version of PowerCLI version trying to connect newer version of vCenter or Esxi server.
Connect-VIServer
$esxcli = Get-VMHost | Get-EsxCli
WARNING:
The Get-EsxCli cmdlet provides a new interface to the ESXCLI functionality.
Use the -V2 parameter to switch to the new cmdlet interface.
Check the cmdlet help for more information.
Scripts that use the old cmdlet interface may no be compatible across two different versions of the ESX server.
The old cmdlet interface is deprecated and will be removed in a future version.
