<# Get the host w/ problem disk group #>

<# ESXCLI Connection #>
$VMHostCLI = $VMHost | Get-ESXCLI -V2

<# Find your problem disk group UUID, in this case I'm looking for a disk group that doesn't exist (blank) #>
$BadDisks = $VMHostcli.vsan.storage.list.invoke() | Where-Object {$_.vsandiskgroupname -eq ""}

<# Your capacity disks should all have the same vSAN Disk Group UUID, we're just confirming it here. #>
$BadDiskGroup = $BadDisks | Select-Object -Unique -Property vsandiskgroupuuid

<# This should return only one assuming you only have one bad disk group, if more than one, then you might have more issues. #>
$BadDiskGroup

<# Below is destructive, only do it if you are ABSOLUTELY sure of what you are doing #>
$vmhostcli.vsan.storage.remove.invoke(@{"uuid"=$BadDiskGroup})
