Check your VSAN disk controllers on VCG with PowerCLI

An easy way of checking your hosts compatibility against vSAN HCL as per VMware.

• Connect to vCenter

• Download latest VSAN HCL details (json file)

• Compare controllers of each host against the VSAN HCL

• Report the state of your infra

Below script is also available on VMware Developer Center as well –

Connect-VIServer myvcenter -user Administrator -password MyPass23

Function Get-CompatibleVSANController {

if (-Not $vSANHCL) {

$vSANHCL = Invoke-WebRequest -Uri http://partnerweb.vmware.com/service/vsan/all.json | ConvertFrom-Json

}

$vSANHCL.data.controller

}

$HBAs = get-vmhost | Get-VMHostPciDevice | where { $_.DeviceClass -eq "MassStorageController" }

Foreach ($HBA in $HBAs) {

$HBAFound = $false

Write-Host "Looking for $($hba.name) from host $($HBA.VMhost)"

Foreach ($entry in Get-CompatibleVSANController) {

$vid = [String]::Format("{0:x}", $HBA.VendorId)

$did = [String]::Format("{0:x}", $HBA.DeviceId)

$svid = [String]::Format("{0:x}", $HBA.SubVendorId)

$ssid = [String]::Format("{0:x}", $HBA.SubDeviceId)

If (($vid -eq $entry.vid) -and ($did -eq $entry.did) -and ($svid -eq $entry.svid) -and ($ssid -eq $entry.ssid) ) {

Write-Host " HBA in $($HBA.VMHost) is $($HBA.Name) which can be found in the HCL as $($Entry.vendor) - $($Entry.Model) at the following URL: `n $($entry.vcglink)" -ForegroundColor Green

$HBAFound = $true

}

}

If (-Not $HBAFound){

Write-Host " $($HBA.Name) in $($HBA.VMHost) is not found!" -ForegroundColor Red

}

}

If you run it the output will look like this:
