switch between admin partitions in NetScaler

Hello,

I have a powershell script trying to find all servers that belong to the various partitions of several NetScaler IPs.

I can retrieve the servers list from default partition, but when I try to switch to the next admin partition I get the below error so I don't think the switch function performs well.

Invoke-NSNitroRestApi : Cannot process argument transformation on parameter 'Payload'. Cannot convert the "PartitionACI
" value of type "System.String" to type "System.Collections.Hashtable".
At D:\NetScaler_scripts\NetScaler_Populate_DB_Table_from_multiple_instances.ps1:401 char:116
+ ... -ResourceType nspartition -Payload $Payload["partitionName"] -Action ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidData: (:) [Invoke-NSNitroRestApi], ParameterBindingArgumentTransformationExceptio
n
+ FullyQualifiedErrorId : ParameterArgumentTransformationError,Invoke-NSNitroRestApi

My switch function is this :

function SwitchPartition{
[CmdletBinding()]
param (
[Parameter(Mandatory=$true)] [PSObject]$NSSession,
[Parameter(Mandatory=$true)] [PSObject]$partition
)
Begin {
Write-Verbose "$($MyInvocation.MyCommand): Enter"
}
Process {
$Payload = @{}
$Payload = @{ partitionname = $partition.partitionname; partitionid = $partition.partitionid; maxbandwidth=$partition.maxbandwidth; maxconn = $partition.maxconn; maxmemlimit = $partition.maxmemlimit; pmacinternal = $partition.pmacinternal }
Write-Host $Payload["partitionname"]
$response = Invoke-NSNitroRestApi -NSSession $NSSession -OperationMethod POST -ResourceType nspartition -Payload $Payload["partitionname"] -Action Switch
}
End {
Write-Verbose "$($MyInvocation.MyCommand): Exit"
}
}

and I'm calling it with this command :

SwitchPartition -NSSession $NSSession -partition $partition

where $partition is this value that I get from a for loop I use to make sure that I enter all admin partitions :

@{partitionname=PartitionACI; partitionid=4; maxbandwidth=10240; maxconn=1024; maxmemlimit=10; pmacinternal=False}

I have also tried to make payload variable like below :

$Payload = @{}
$Payload = @{ partitionname = $partition.partitionname }

and

$response = Invoke-NSNitroRestApi -NSSession $NSSession -OperationMethod POST -ResourceType nspartition -Payload $Payload -Action Switch

but again it doesn't work.

Any ideas please ?

Thank you in advance.
