Horizon View API (HV Helper Module) - Run CMDlets against multiple HVServers

[beutlern]

Dear all,

how do you guys run cmdlets like "get-hvmachinesummary" against multiple connected hvservers?

If i run the command, stating nothing, it just runs against the last connected hvserver.

If i try to specify multiple it asks for a certain variable type i was unable to provide so far.

PS C:\WINDOWS\system32> Get-HVMachineSummary -HvServer $global:DefaultHVServers

Get-ViewAPIService : Expected hvServer type is ViewServerImpl, but received: [ViewServerInterop[]]

Thanks for any suggestions

The HVServer parameter doesn't accept an array, just a single HVServer.

Try like this

$global:DefaultHVServers | %{

    Get-HVMachineSummary -HvServer $_

}

Trying to connect multiple pod's connection servers to get the pools specific information of "reuse computer objects" script but unable to connect multiple connection servers.

Connect-HVServer : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Server'. Specified method is not supported.

Same issue, the cmdlet doesn't accept an array, only a single String.
Run the cmdlet in a loop

Hi LucD,

I'm new to this scripting, can you please give any sample script which uses the cmdlet in loop. 
From that i can try to prepare my script.

Thank you.

When you are connected to all Connection servers, you could do

foreach($cServer in $global:DefaultHVServers){
   Get-HVMachineSummary -HvServer $cServer
}

This is the most reliable way to split an array into its single elements:

($global:DefaultHVServers).Foreach({Get-HVMachineSummary -HvServer $_})

You can use it for any CmdLet in pwsh.
If you use Foreach-Object (which works different from the foreach command) you get 3 parts that can be used.

BEGIN PROCESS END.
In the BEGIN part you do some starting command(s) like reading a file that contains servernames.
In the PROCESS part you getter all info in a loop of command(s) that have to repeat.
In the END part you work the magic of changing things in to 1 final object, like an output to another cmdlet or a file or the screen.

For a better understanding look at:
help foreach -Examples

If you realy want to learn Powershell search for "Don Jones".
