Targets, Devices and Paths, Oh My!!

[Troy_Clavell]

I'm hoping you all can help.  I am looking for a script that will connect to vCenter(4.1U1) then walk all the ESXi Hosts (4.1) check the hba's (storage adapters) and gather targets, devices and paths.  If there is a discrepancy email me the findings. ( I will be adding this script as part of a scheduled task)

An example would be 1 hba has Targets: 2 Devices: 25 Paths: 50  while the other hba has something different.

Yes, I can use alarms but, I am just being overly cautious.

Hi Troy,

the next script gives you all the counters. Now I have to think about an extension to this script that does the compare and emails if it finds a discrepancy.

Get-Cluster | Sort-Object -property Name | ForEach-Object {
  $Cluster = $_
  $Cluster | Get-VMHost | Sort-Object -property Name | ForEach-Object {
    $VMHost = $_
    $VMHost | Get-VMHostHba | Sort-Object -property Device | ForEach-Object {
      $VMHostHba = $_
      $ScsiLun = $VMHostHba | Get-ScsiLun
      If ($ScsiLun) {
        $ScsiLunPath = $ScsiLun | Get-ScsiLunPath | Where-Object {$_.Name -like "$($VMHostHba.Device)*"}
        $Targets = ($ScsiLunPath | `
          Group-Object -Property SanID | Measure-Object).Count
        $Devices = ($ScsiLun | Measure-Object).Count
        $Paths = ($ScsiLunPath | Measure-Object).Count
      }
      Else {
        $Targets = 0
        $Devices = 0
        $Paths = 0
      }
      $Report = "" | Select-Object -Property Cluster,VMHost,HBA,Targets,Devices,Paths
      $Report.Cluster = $Cluster.Name
      $Report.VMHost = $VMHost.Name
      $Report.HBA = $VMHostHba.Device
      $Report.Targets = $Targets
      $Report.Devices = $Devices
      $Report.Paths = $Paths
      $Report
    }
  }
}

Regards, Robert
