Fetching HBA details for ESXi

Today i came across the scenario where one of our host  not seeing few luns from particular storage array. Upon analyzing though we have redundant hba’s hosts were not logging properly into switch. Storage team decided to check all paths details for each and every ESXi host.

Our environment is little big with multiple locations and multiple clusters. So its not easy for us to sit and work with storage team on each and every host. i worked on a script which will pull a host name, hba name, cluster name, WWN, target, lun and path counts export into excel sheet. Script is as below, which may help you at some point.

$vmhosts = Get-VMHost
$results = @()
foreach($vmhost in $vmhosts)
{

    foreach($hba in (Get-VMHostHba -VMHost $vmhost -Type “FibreChannel”))
    {
        $wwn = $hba | Select @{N=”WWN”;E={“{0:X}” -f $_.PortWorldWideName}}
        $cls = $vmhost | select @{N=”Cluster”;E={Get-Cluster -VMHost $_}}
        $target = ((Get-View $hba.VMhost).Config.StorageDevice.ScsiTopology.Adapter | where {$_.Adapter -eq $hba.Key}).Target
        $luns = Get-ScsiLun -Hba $hba  -LunType “disk” -ErrorAction SilentlyContinue
        $Paths = ($target | %{$_.Lun.Count} | Measure-Object -Sum).Sum
        $cls = $vmhost | select @{N=”Cluster”;E={Get-Cluster -VMHost $_}}

 $value =New-Object PSObject
$value |Add-Member -MemberType NoteProperty -Name “HostName” -Value $vmhost
$value |Add-Member -MemberType NoteProperty -Name “HBAName” -Value $hba.Device
$value |Add-Member -MemberType NoteProperty -Name “WWN” -Value $wwn.WWN
$value |Add-Member -MemberType NoteProperty -Name “Target” -Value $target.count
$value |Add-Member -MemberType NoteProperty -Name “Luns” -Value $luns.Count
$value |Add-Member -MemberType NoteProperty -Name “NumberOfPaths” -Value $Paths
$value |Add-Member -MemberType NoteProperty -Name “Cluster” -Value $cls.Cluster
$results+=$value
        }

    }
