Returning the product information about the ESX host with a simple command

Get-VMHost | % { (Get-View $_.ID).Config.Product }

I found this little bit code useful on the forums. It returns a list of virtual machines and their mac addresses.

<code>Get-VM | select name, @{Name="MAC"; expression={foreach($nic in (Get-View $_.ID).guest.net) {$nic.macAddress}}} </code>

Note that the forums are putting the code tags in front of and at the end of the line of code. That is not part of the actual code that you run in Powershell

I found this while surfing the forums this little bit of code will place an ESX Host in maintenance mode. I wonder what other values might exist for the -State switch?

Get-VMHost -Name <hostname> | Set-VMHost -State maintenance

This little snippet of PoweShell Code will create a virtual switch on an ESX Host. I found this while hunting through the VMware comunities for why I couldn't create a portgroup with Powershell. Using this code I was able to create a Virtual Switch called vSwitch1 with a VM portgroup called Production. I still have no idea what the policy setting does or do I know of any other values that could go there.

$ESXhost = "sc-gallium04.pso.vmware.com"

$vSwitch = "vSwitch1"

$user = "scriptuser"

$password = "vmware"

$VC = "10.18.138.187"

*
Get-VIServer $VC -User $user -Password $password

*

$NewSwitch = New-VirtualSwitch -vmhost (*Get-VMHost* $ESXhost ) -Name $vSwitch -NIC "vmnic1"

$net = Get-View(Get-View(*Get-VMHost* -Name $ESXHost).ID).configmanager.networksystem

$PortgroupSpec = New-Object vmware.Vim.hostportgroupspec

$PortgroupSpec.vswitchname = $vSwitch

$PortgroupSpec.Name = "Production"

$PortgroupSpec.policy = New-Object vmware.Vim.HostNetworkPolicy

$net.AddPortgroup($PortGroupSpec)
