How to Count Number of Paths in Fibre Channel VMWare Storage Using PowerCLI

A quick script to count the number of paths for FC ESxi HBAs for audit and troubleshooting connectivity issues using powercli.

##Count Number of Paths Fibre Channel

$esxName = 'uk3p-esxi01*','uk3p-esx02*','uk3p-esx03*'
$report= @()
$esxilist = Get-VMHost -Name $esxName
 
foreach( $esxvm in $esxilist){
$esx = Get-VMHost -Name $esxvm
$esxcli = Get-EsxCli -VMHost $esxvm
$hba = Get-VMHostHba -VMHost $esx -TypeFibreChannel | Select -ExpandProperty Name
$esxcli.storage.core.path.list() |
Where{$hba -contains $_.Adapter} |
Group-Object -Property Device | %{
     $row = "" | Select ESXihost, Lun, NrPaths
     $row.ESXihost = $esxvm.name
     $row.Lun = $_.Name
     $row.NrPaths = $_.Group.Count
     $report += $row
  }
}
 
$report | Export-Csv esx-lun-path.csv -NoTypeInformation -UseCulture

I recently updated my powercli version and realised you can just issue this command to retrieve WWN from a Host

Get-VMHost uk3p-esxi01.lab.local | Get-VMHostHba | ft -a
