What happens to session if Disconnect-ViServer is not called?

[fixitchris]

What happens to an active session if Disconnect-ViServer is not called and powershell exits?

The problem I am running into is with PowershellASP:

The code here works great:

But, if I add :

<% Disconnect-VIServer -server $host1  -confirm:$false %>

Then PoweshellASP gives this error on Disconnect-VIserver cmdlet:

 Cannot invoke this function because the current host does not implement it.

Any ideas?

[admin · Accepted solution]

The trouble is actually due to Disconnect-VIServer trying to change the window title, which PowerShellASP doesn't support (I surmise).

You can use this code to disconnect:

(get-view serviceinstance).Client.Logout()

That piece of code completed ok. Thanks.

Can you explain or point me tosome documentation for

(get-view serviceinstance).Client.Logout()

especially the

(get-view serviceinstance)

cmdlet reference, reflector?

[yboychev]

+"The ServiceInstance is a managed object. It is the

singleton root object of the inventory on both vCenter servers and servers

running on standalone host agents. The server creates the ServiceInstance automatically, and also

automatically creates the various manager entities that provide services in the

virtual environment."+ You can search for more info on the ServiceInstanse managed object in: http://www.vmware.com/support/developer/vc-sdk/visdk25pubs/ReferenceGuide

On the other hand the Get-View cmdlet retrieves the view of a managed object. A view is a static copy of a server-side managed object. It is not updated autoamticaly if you update the server-side object (you have to call the UpdateViewData() method of the view object) You can find more info and examples in AdminGuide document located in the instalation folder of the toolkit

Thanks for the explanation...

$MyHost = Connect-VIServer -Server $creds.host -User $creds.User -Password $creds.Password;
$MyHostMO = Get-VMHost $MyHost | Get-View;

Why can't I do :

$MyHostMO = Get-View Get-VMhost  

[admin]

If you run "help get-view" you'll see that it has 3 signatures.

If you use:

Get-VMHost | Get-View

PowerShell will use the 3rd signature, since you're piping an object in and this is the only signature that accepts pipeline input. That means that the thing piped in is cast to a VIObject.

For tthe code

Get-View Get-VMHost

, Get-VMHost is just a string, which Get-View will try to treat as an ID. A similar bit of code that would work is:

Get-View -VIObject (Get-VMHost)

. Personally I like the pipeline way of doing it a lot better.

[fixitchris]

I get it...

$MyDS = Get-Datastore -Name Datastore1 | Get-View;
$MyDS2 = Get-View -VIObject (Get-Datastore -Name Datastore1)
$MyDS3 = Get-View -VIObject (Get-Datastore)

And I am assuming that

$MyDS3 = Get-View -VIObject (Get-Datastore)

would return a collection of all datastores?

And VIOBJECT is just a Manged Object of Managed Entity abstract class?

So in Get-View can only be of Vim.ManagedObjectReference.

So...

$MySI = (Get-View ServiceInstance);

Trying to use reflector to dig deeper and for some items it asks for VimService20 and VimService25. Are those DLLs available?
