Hi Lucd,
I required one help..Since we are migrating all ESXI to 8, Wanted to get information for Multiple ESXI like whether they are booting from Local DISK or SAN LUN.
Earlier below Script use work and I got from William Site, currently it is not throwing any error nor getting output.
Below is the Script
Function Get-ESXiBootDevice {
<#

.DESCRIPTION
This function identifies how an ESXi host was booted up along with its boot
device (if applicable). This supports both local installation to Auto Deploy as
well as Boot from SAN.
.PARAMETER VMHostname
The name of an individual ESXi host managed by vCenter Server
.EXAMPLE
Get-ESXiBootDevice
.EXAMPLE
Get-ESXiBootDevice -VMHostname esxi-01
#>
param(
[Parameter(Mandatory=$false)][String]$VMHostname
)
if($VMHostname) {
$vmhosts = Get-VMhost -Name $VMHostname
} else {
$vmhosts = Get-VMHost
}
$results = @()
foreach ($vmhost in ($vmhosts | Sort-Object -Property Name)) {
$esxcli = Get-EsxCli -V2 -VMHost $vmhost
$bootDetails = $esxcli.system.boot.device.get.Invoke()
# Check to see if ESXi booted over the network
$networkBoot = $false
if($bootDetails.BootNIC) {
$networkBoot = $true
$bootDevice = $bootDetails.BootNIC
} elseif ($bootDetails.StatelessBootNIC) {
$networkBoot = $true
$bootDevice = $bootDetails.StatelessBootNIC
}
# If ESXi booted over network, check to see if deployment
# is Stateless, Stateless w/Caching or Stateful
if($networkBoot) {
$option = $esxcli.system.settings.advanced.list.CreateArgs()
$option.option = "/UserVars/ImageCachedSystem"
try {
$optionValue = $esxcli.system.settings.advanced.list.Invoke($option)
$bootType = $optionValue.StringValue
} catch {
$bootType = "stateless"
}
}
# Loop through all storage devices to identify boot device
$devices = $esxcli.storage.core.device.list.Invoke()
$foundBootDevice = $false
foreach ($device in $devices) {
if($device.IsBootDevice -eq $true) {
$foundBootDevice = $true
if($device.IsLocal -eq $true -and $networkBoot -and $bootType -ne "stateful") {
$bootType = "stateless caching"

$bootIsSSD = $device.IsSSD
$bootIsUSB = $device.IsUSB
}
}
# Pure Stateless (e.g. No USB or Disk for boot)
if($networkBoot-and $foundBootDevice -eq $false) {
$bootModel = "N/A"
$bootVendor = "N/A"
$bootSize = "N/A"
$bootIsSAS = "N/A"
$bootIsSSD = "N/A"
$bootIsUSB = "N/A"
}
$tmp = [pscustomobject] @{

BootType = $bootType;

Kindly help me out at the earliest...Since little urgent.
Thanks in Advance.
