Powershell Pool creation only adding 1 node

Hi

Seems like you've got some mixup with the array dimensions:

$MemberDefAofA[0][0] = $MemberDef

Adding it to an array

$Members += $MemberDefAofA

would create a tri-dimensional array, I guess.

Try something like this (had to rewrite it since I did not know how you declared the previous variables in your script):

Initialize Snapin

if ( (Get-PSSnapin | Where-Object { $_.Name -eq "iControlSnapIn"}) -eq $null ){
    Add-PSSnapIn iControlSnapIn
}

$User = "iUser"
$Password = "mypassword"
$Partition = "Common"
$BigIP = "192.168.161.10"


Declare variables
$ObjMembers = @()
$NodeDict = @{}

Connect to the BigIP
$Success = Initialize-F5.iControl -HostName $BigIP -Username $User -Password $Password

Get an iControl Handle
$F5 = Get-F5.iControl

$PoolMembers = ("192.168.20.1", "192.168.20.2")
$PoolName = "PSPool"
$Members = @()
$LBMethod = "LB_METHOD_LEAST_CONNECTION_MEMBER"
$MonitorName = "https"

$MemberDefAofA = New-Object -TypeName "iControl.CommonAddressPort[]" 2

$MemberDef = New-Object -TypeName iControl.CommonAddressPort
$MemberDef.address = "PajoIIS"
$MemberDef.port = 8011

$MemberDefAofA[0] = $MemberDef
$MemberDef = New-Object -TypeName iControl.CommonAddressPort
$MemberDef.address = "PajoIIS"
$MemberDef.port = 8012
$MemberDefAofA[1] = $MemberDef

(Get-F5.iControl).LocalLBPool.Create_v2((,$PoolName), (,$LBMethod), (,$MemberDefAofA))

Just a comment. The create_v2 method would technically expect the pool name and load balancing methods to be arrays too. It accepts it, but it's... "prettier" to it that way. 🙂
