Change portgroup of VMs with specific IP adress

[TylerDurden77]

Hi,

I'm moving ESX servers from one vCenter to another.

VMs that have been migrated to my new vCenter/DVswitch don't have a correct PG configured.

My setup:

PG10 = 192.168.10.0/24

PG11 = 192.168.11.0/24

PG12 = 192.168.12.0/24

Etc...

Found this script somewhere which solves my problem per vlan

$sourceVMhost = "esx03"

$VMnameFilter = "*"

$IPFilter = "192.168.10.*"

$logfolder = "c:\MigrationLogs"

$getvms = Get-VMhost $sourceVMhost | Get-VM | where name -Like $VMnameFilter | Select Name, @{ L = "IP Address"; E = { ($_.guest.IPAddress[0]) } } | where "IP Address" -Like $IPFilter | select -ExpandProperty name

foreach ($vm in $getvms)

{

$NEWDPG = Get-VDSwitch -Name dvSwitch-prod | Get-VDPortgroup -Name 'PG10'

get-vm $vm | Get-NetworkAdapter | Set-NetworkAdapter -NetworkName $NEWDPG -Confirm:$false

If (!$error)

{ Write-Output $vm, $error[0] | out-file -append -filepath "$logfolder\success.log" }

Else

{ Write-Output $vm, $error[0] | out-file -append -filepath "$logfolder\failed.log" }

Above script works fine but I have to run it many times and change the $IPFilter and $NEWDPG.   (My VMs are spread out on vlan10-20)

Possible to use some kind of If statement to accomplish this task in one single script?

Regards

You could try something like this

Remove the WhatIf switch on the Set-NetworkAdapter cmdlet when you are sure everything is working as expected.

$sourceVMhost = "esx03"

$ipTabText = @'

Range,PGName

192.168.10,PG10

192.168.11,PG11

192.168.12,PG12

192.168.13,PG13

192.168.14,PG14

192.168.15,PG15

192.168.16,PG16

192.168.17,PG17

192.168.18,PG18

192.168.19,PG19

192.168.20,PG20

'@

$ipTab = @{}

$ipTabText | ConvertFrom-Csv | %{

    $ipTab.Add($_.Range,$_.PGName)

}

$logfolder = "c:\MigrationLogs"

Get-VMHost -Name $sourceVMhost | Get-VM |

Group-Object -Property {$_.Guest.IPAddress[0].Split('.')[0..2] -join '.'} | %{

    $subnet = $_.Name

    $pg = Get-VDSwitch -Name dvSwitch-prod | Get-VDPortgroup -Name $ipTab[$subnet]

    $_.Group | %{

        Get-NetworkAdapter -VM $_ | Set-NetworkAdapter -NetworkName $pg -Confirm:$false -WhatIf

        If (!$error)

        { Write-Output $vm, $error[0] | out-file -append -filepath "$logfolder\success.log" }

        Else

        { Write-Output $vm, $error[0] | out-file -append -filepath "$logfolder\failed.log" }

    }

}

Hi LucD,

Thanks for your quick response.

Testing in my "test" environment where I have some other PG names.

When I run :

$sourceVMhost = "esx08"

$ipTabText = @'

Range,PGName

172.30.155,net-155

172.30.174,net-175

'@

$ipTab = @{}

$ipTabText | ConvertFrom-Csv | %{

    $ipTab.Add($_.Range,$_.PGName)

}

I get this error :

Exception calling "Add" with "2" argument(s): "Key cannot be null.

Parameter name: key"

At line:19 char:5

+     $ipTab.Add($_.Range,$_.PGName)

+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + FullyQualifiedErrorId : ArgumentNullException

Any advice?

Looks like there are some blank lines inserted in the code I gave.

That might have happened during the copy/paste on your side.

Try with the attached file, that avoids these copy/paste issues.

Thank you LucD

Works like a charm
