Adding more functinality to found script that unmounts LUNs.

I found this small and straight forward handy little script by David Stamen (davidstamen.com)
https://davidstamen.com/2015/09/14/using-powercli-to-detach-luns/

# PowerCLI Script for detaching luns from a cluster

# @davidstamen

# http://davidstamen.com

 

$LunIDs = "naa.6000000001","naa.600000002"

$Clustername = "MyCluster"

 

function Detach-Disk {

    param(

        [VMware.VimAutomation.ViCore.Impl.V1.Inventory.VMHostImpl]$VMHost,

        [string]$CanonicalName    )

 

    $storSys = Get-View $VMHost.Extensiondata.ConfigManager.StorageSystem

    $lunUuid = (Get-ScsiLun -VmHost $VMHost | where {$_.CanonicalName -eq $CanonicalName}).ExtensionData.Uuid

 

    $storSys.DetachScsiLun($lunUuid)

}

 

$ClusterHosts = Get-Cluster $Clustername | Get-VMHost

 

Foreach($VMHost in $ClusterHosts)

{

    Foreach($LUNid in $LunIDs)

    {

        Write-Host "Detaching" $LUNid "from" $VMHost -ForegroundColor "Yellow"

        Detach-Disk -VMHost $VMHost -CanonicalName $LUNid

    }

}

This almost does it for me, I still need to connect to every host involved and removed the detached LUNs

Procedure being first SSH to host and then running the CLI commands:

esxcli storage core device detached list

and then

esxcli storage core device detached remove -d naa.6000000001

esxcli storage core device detached remove -d naa.6000000002

and so on.

I cant help to think they ought to be a way to add this to David's existing script. Utilizing the $LunIDs and $VMHost that have already been defined.

All i seem to be finding are standalone scripts and would appear to be way more convoluted than they need to be.

Any suggestions or pointers?
