Script to output WWN Datacenter Cluster Host

[RobTheNewGuy]

Hi All,

I am looking to create a script to output:

WWN with WWP, Datacenter, Cluster, Host

Not sure how to start with this one. I'm assuming I would start by using Get-Datacenter and then get-content from there.

Any help much appreciated,

Rob.

Since WWN can be retriever for HBA and/or LUN, you could do

foreach($dc in Get-Datacenter){

   foreach($cluster in Get-Cluster -Location $dc){

      foreach($esx in Get-VMHost -Location $cluster){

...

      }

   }

}

In the inner loop you could then get the HBA and/or LUN of the ESXi and extract the WWN.

Is that what you are looking for ?

I think thats the one. The output needs to look like this:

WWN, Datacenter, Cluster, Host

20010025B5331E1F 20000025B5122B1F, VI_25Metro, SVCuster02, ucs12.vi.local

20010025B5331E1F 20000025B5122A1F, VI_25Metro, SVCuster02, ucs12.vi.local

20010025B5331E0F 20000025B5122B0F, VI_25Metro, SVCuster02, ucs11.vi.local

Thanks again.

Luc, do you have any time to help me with obtaining my desired output?

Rob,

You can try the following code. It should be a pretty good starter point at the very least. I don't have a FC HBA in my home lab to work out any kinks with the WWN info so that'll have to wait until tomorrow.

$vmhosts = Get-VMHost

$HBAInfo = @()

Foreach ($vmhost in $vmhosts) {

    $HBAs = $vmhost | Get-VMHostHba -Type FibreChannel

    $DC = (Get-Datacenter -VMHost $vmhost).Name

    $Cluster = (Get-Cluster -VMHost $vmhost).Name

    Foreach ($HBA in $HBAs) {

        $Details = "" | Select WWN, Datacenter,Cluster,Host

        $Details.WWN = $HBA.PortWorldWideName

        $Details.Datacenter = $DC

        $Details.Cluster = $Cluster

        $Details.Host = $vmhost.Name

        $HBAInfo += $Details

    }

}

$HBAInfo

Sure, try something like this

foreach($dc in Get-Datacenter){
  foreach($cluster in Get-Cluster -Location $dc){
    foreach($esx in Get-VMHost -Location $cluster){
      Get-VMHostHba -VMHost $esx -Type FibreChannel | 
      Select @{N="DC";E={$dc.Name}},@{N="Cluster";E={$cluster.Name}},
        @{N="Host";E={$esx.Name}},Name,
        @{N="HBA Node WWN";E={"{0:x}" -f $_.NodeWorldWideName}},
        @{N="HBA Port WWN";E={"{0:x}" -f $_.PortWorldWideName}}
    }
  }
}

Here is my revised code that gets everything and was checked to work. LucD's works just as well if you want to use his with one caveat that probably won't apply. If you happen to have a host that is not in a cluster (very few cases I'm sure that you would set things up this way) it will not return any results for that host.

$vmhosts = Get-VMHost

$HBAInfo = @()

Foreach ($vmhost in $vmhosts) {

    $HBAs = $vmhost | Get-VMHostHba -Type FibreChannel

    $DC = (Get-Datacenter -VMHost $vmhost).Name

    $Cluster = (Get-Cluster -VMHost $vmhost).Name

    Foreach ($HBA in $HBAs) {

        $Details = "" | Select WWN, WWP, Datacenter, Cluster, Host

        $Details.WWN = "{0:x}" -f $HBA.NodeWorldWideName

        $Details.WWP = "{0:x}" -f $HBA.PortWorldWideName

        $Details.Datacenter = $DC

        $Details.Cluster = $Cluster

        $Details.Host = $vmhost.Name

        $HBAInfo += $Details

    }

}

$HBAInfo
