Dead Paths list using powershell

Dead Paths are always been an headache for vmware admin. Some cases that leads host into not responding state. Here i am sharing powershell script to pull dead path list from vcenter. you can modify it accordingly if you want to run it for specific cluster/host.

#Get list of ESXi Hosts
# remove -location parameter if you want to run for complete vcenter
$vmhosts = @(Get-VMHost -Location Dev)
$i=0

$result = ForEach ($vmhost in $vmhosts) {
    $i++
    Write-Progress -Activity "Scanning hosts" -Status ("Host: {0}" -f $vmhost.Name) -PercentComplete ($i/$vmhosts.count*100) -Id 0
    $hbas = $vmhost | Get-VMHostHba
