WWN – ThepHuck

Updated: Finding WWNs for HBAs in ESXi hosts, now with get-vmhosthba

This is an update to my original get-WWN script using Get-View. Get-VMHostHba was pointed out to me by Robert van den Nieuwendijk, vExpert 2012, so I wanted to provide an update to my original post HERE. I attached the ps1 file at the end.

With the addition of get-vmhosthba in PowerCLI, you can get this information somewhat easier. At line 46

$hbas = Get-View (Get-View (Get-VMHost -Name $vmhost).ID).ConfigManager.StorageSystem

1	$hbas = Get-View (Get-View (Get-VMHost -Name $vmhost).ID).ConfigManager.StorageSystem

becomes

$hbas = Get-VMHostHba -vmhost $vmhost -Type FibreChannel

1	$hbas = Get-VMHostHba -vmhost $vmhost -Type FibreChannel

Since that pulls only fibre channel HBAs, the foreach changes to simply $hba in $hbas, and the if statement is no longer needed (line 47-50):

foreach ($hba in $hbas){
$wwpn = "{0:x}" -f $hba.PortWorldWideName
Write-Host -foregroundcolor green `t "World Wide Port Name:" $wwpn
}

foreach ($hba in $hbas){

$wwpn = "{0:x}" -f $hba.PortWorldWideName

Write-Host -foregroundcolor green `t "World Wide Port Name:" $wwpn

}

Here’s the new version –> Get-WWN.ps1

Finding WWNs for HBAs in multiple ESX or ESXi hosts, standalone or clustered

**Update May 07, 2012 – Use the new script here: Updated: Finding WWNs for HBAs in ESXi hosts, now with Get-VMHostHba

When building a new cluster, your storage team (or you) may need to add several hosts into the shared storage zone. It’s a pain to go to each host, configuration, storage adapters, then copy out the WWN.

With this script, you can supply a vCenter server and Cluster/Folder/Datacenter (any logical container) and it will list all the WWNs for Fibre Channel devices. But what if you don’t have vCenter stood up yet? No problem, you can also supply a list of ESX/ESXi hosts to scan.

Shawn & I built this because we have 20 hosts we need the WWNs from to provide to our storage team, and vCenter isn’t alive yet.

Our script:
