Hello,
To start here are the versions of everything:
vCenter - 5.5
VCO - 5.5
PowerShell Plugin - 1.0.4
PowerShell Host - Server 2012 R2 (Powershell 4.0)
DHCP Server - Server 2012 R2
DNS Server - Server 2012 R2
I've been beating my head against the wall trying to figure out how to get this Powershell script to run in VCO.
I've tried a few different methods and always get the same error code:
PowerShellInvocationError: Errors found while executing script Microsoft.Management.Infrastructure.CimException: Failed to retrieve free IP address for 192.168.175.0 on server mydc01.domain.local. at Microsoft.Management.Infrastructure.Internal.Operations.CimAsyncObserverProxyBase`1.ProcessNativeCallback(OperationCallbackProcessingContext callbackProcessingContext, T currentItem, Boolean moreResults, MiResult operationResult, String errorMessage, InstanceHandle errorDetailsHandle)
Here is my script that runs perfectly from the command line
param ( [string]$hostname = $(throw "-hostname is required."), [string]$macaddress = $(Get-Date -format yy-MM-dd-hh-mm-ss), [string]$dhcpserver = $(throw "-dhcpserver is required."), [string]$scopeid = $(throw "-scopeid is required."), [string]$dnszone = $(throw "-dnszone is required.")
)
# ^ Make sure all the needed variables are passed through^
#Grab a free IP address from the DHCP Server
$vmIP = Get-DhcpServerv4FreeIPAddress -ComputerName $dhcpserver -ScopeId $scopeid
#Create an A recored in DNS for the VM
Add-DnsServerResourceRecordA -Name $hostname -ZoneName $dnszone -CreatePtr -IPv4Address $vmIP -CimSession $dhcpserver
#Create a DHCP reservation for the VM
Add-DhcpServerv4Reservation -Name $hostname -ScopeId $scopeid -IPAddress $vmIP -ClientId $macaddress.ToString() -Description "$hostname - Generated by OnDemand" -CimSession $dhcpserver
#Get the DHCP scope options to set on the VM
$scopeOptions=Get-DhcpServerv4OptionValue -ComputerName $DHCPServer -ScopeId $scopeid
#Get the scope
$scope=Get-DhcpServerv4Scope -ComputerName $dhcpserver -ScopeId $scopeid
#Loop through the scope options and set the options to variables
foreach ($option in $scopeOptions){ #If the scope options matches the number then set the variable switch ($option.OptionId){ #Option ID 3 is gateway 3 {$vmGateway=$option.Value[0]} #Option ID 6 is an Array of DNS Servers 6 {$vmDnsArray=$option.Value} #Option ID 15 is the DNS Name 15 {$vmDnsDomainName=$option.Value[0]} #Option ID 44 is an Array of WINS Servers 44 {$vmWinsArray=$option.Value} }
}
#Set the subnetmask
$vmSubnetMask=$Scope.SubnetMask.IPAddressToString
#Print out all of the variables
$vmIP
$vmSubnetMask
$vmGateway
$vmDnsArray
$vmDnsDomainName
$vmWinsArray
I call this script as follows:
C:\> powershell.exe -file -hostname "test1234" -dhcpserver "mydc01.domain.local" -scopeid "192.168.175.0" -dnszone "domain.local"
I've tried multiple different workflows in VCO (Invoke a Powershell script, Invoke an external script, & Invoke a script via API) and each an every one of them fails with the above error message.
I think it has something to do with the VCO plugin not being aware of the DHCP and DNS PowerShell libraries.
I see that there are "Snapins" in VCO under Administer > Powershell > HostName
Do I need to somehow add a snapin for those powershell libraries?
Any help would be greatly appreciated.
Thank you,
Cody Hill
