How to get WWN of all your ESXi Servers from Power CLI
Some time require to know our ESXi servers WWN information for your record if you are having Cisco UCS or you are coordinating with Storage Administrator .That time you require WWN to MAP new LUN or RDM or MDS Switch Zoaning.
I got a script and tested it working fine . Its gives you Cluster Name Host Name HBA and WWN .
$vcenter = "192.168.1.1"
$outputFile = "C:\PCLITEST\All-WWNs-" + (get-date -Format yyyy-MM-dd-HHmm) + ".csv"
"Connecting vCenter servers ..."
$report = @()
foreach ($cluster in (Get-Cluster)) {
("Processing cluster " + $cluster.Name + " ...")
foreach ($vhost in (Get-VMHost -Location $cluster.Name)) {
(" Processing host " + $vhost.Name + " ...")
$row = "" | select Cluster, VMHost, Dev1, WWN1, Dev2, WWN2, Dev3, WWN3, Dev4, WWN4
$row.Cluster = $cluster.Name
$row.VMHost = $vhost.Name
foreach ($hba in (Get-VMHostHba -VMHost $vhost -Type FibreChannel)) {
if ($hba.ExtensionData.Status -eq "online") {
$wwn = ("{0:X}" -f $hba.PortWorldWideName) -replace '(..(?!$))','$1:'
if ($row.WWN1 -eq $null) {
$row.Dev1 = $hba.Device
$row.WWN1 = $wwn
} elseif ($row.WWN2 -eq $null) {
$row.Dev2 = $hba.Device
$row.WWN2 = $wwn
} elseif ($row.WWN3 -eq $null) {
$row.Dev3 = $hba.Device
$row.WWN3 = $wwn
} elseif ($row.WWN4 -eq $null) {
$row.Dev4 = $hba.Device
$row.WWN4 = $wwn
}
}
}
$report += $row
}
}
"Exporting report data to $outputFile ..."
$report | Export-CSV -Path $outputFile
