Snap-in installed but cmdlets not visible

That's odd. What line is the "Get-Command" error coming from? I don't see you using Get-Command in the code.

 

 

After you successfully call Add-PSSnapin, what is the output of the following

 

 

PS> Get-F5.Commands

 

 

or

 

 

PS> Get-Command *-F5.*

 

 

or

 

 

PS> Get-Command Initialize-F5.iControl

Sorry,

The Get-Command error happens at this line

 $success = Initialize-F5.iControl -HostName $bigip -Username $user -Password $pass 

additionally after I run it once (and hit the Add-PSSnapIn the first time if I run the commands you suggested I get the same error e.g.

Get-Command : The term 'Initialize-F5.iControl' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the
 name, or if a path was included, verify that the path is correct and try again.
At line:1 char:12
+ Get-Command <<<<  Initialize-F5.iControl 
    + CategoryInfo          : ObjectNotFound: (Initialize-F5.iControl:String) [Get-Command], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException,Microsoft.PowerShell.Commands.GetCommandCommand 

Ok, let's start from the beginning.

First you need to run the setupSnapin.ps1 file in the "c:\program files (x86)\F5 Networks\iControlSnapin" installation directory. This will add the snapin to the registry. Maybe you missed this step...

PS C:\Program files (x86)\F5 Networks\iControlSnapin> .\setupSnapin.ps1 -force

Keep in mind that you will need run this as Administrator as it updatest the registry.

Then this command should then return the following:

PS> Get-PSSnapin -Registered iControlSnapin
Name        : iControlSnapIn
PSVersion   : 2.0
Description : iControl Snap-in for F5 Device Management

Then you'll need to add the snapin to your current runspace

PS> Add-PSSnapin iControlSnapin

Then running the Get-PSSnapin should return the snapin info:

PS> Get-PSSnapin iControlSnapin
Name        : iControlSnapIn
PSVersion   : 2.0
Description : iControl Snap-in for F5 Device Management

At this point, the snapin is loaded in the runspace and you should be able to get the exported cmdlets from the snapin:

PS> Get-Command -Module iControlSnapin
CommandType     Name
-----------     ----
Cmdlet          Add-F5.LTMPoolMember
Cmdlet          Add-F5.LTMVirtualServerRule
  ...

And the Initialize-F5.iControl cmdlet should be there too

PS> Get-Command -Module iControlSnapin Initialize-F5.iControl
CommandType     Name
-----------     ----
Cmdlet          Initialize-F5.iControl

Could you run through those steps and see where things break down.

Sorry, I wasn't clear.

 

 

The installation and registration of the snap-in works. As does my script (it removes nodes from a pool during code deployment), however the script only works the first time. Here's what happens

 

 

I open the myscript.ps1 in powershell ISE and run it. It h runs through the code block in my first post:

 

 

 if ( (Get-PSSnapin | Where-Object { $_.Name -eq "iControlSnapIn"}) -eq $null ) { Add-PSSnapIn iControlSnapIn } $success = Initialize-F5.iControl -HostName $bigip -Username $user -Password $pass 

 

 

and, doesn't find the snap in so it runs the Add-PSSnapIn command returns success and goes on to execute the remainder of the script.

 

 

If I then run this command, I see that the snap-in is present in my current runtime

 

 PS C:\Windows\system32> Get-PSSnapin | Where-Object { $_.Name -eq "iControlSnapIn"} Name : iControlSnapIn PSVersion : 2.0 Description : iControl Snap-in for F5 Device Management 

 

 

However calling an F5 specific cmdlet after that doesn't work after that. Example:

 

 

 PS C:\Windows\system32> Get-Command -Module iControlSnapin Initialize-F5.iControl Get-Command : The term 'Initialize-F5.iControl' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:12 + Get-Command <<<< -Module iControlSnapin Initialize-F5.iControl + CategoryInfo : ObjectNotFound: (Initialize-F5.iControl:String) [Get-Command], CommandNotFoundException + FullyQualifiedErrorId : CommandNotFoundException,Microsoft.PowerShell.Commands.GetCommandCommand 

 

Subsequent runs of my script also fail after this because of it's dependacy on F5 cmdlets

 

edit: forum styling grrrrrrrr

 

What does "Get-Command -Module iControlSnapin" return after you've successfully added the Snapin? If it's an empty list them something is wrong with the Snapin Install. I've been using the snapins for years now and haven't had this issue with the command prompt or ISE.

Yep, it's empty.

PS C:\Windows\system32> Get-Command -Module iControlSnapin
