Gather HP iLO information using PowerShell

Please begin by reading my previous post where I show how to retrieve physical hard disk information such as model numbers and firmware versions using the HP Insight Management WBEM providers.

A few days ago, as HP published an advisory regarding firmware of their Integrated Lights-Out (iLO) management controllers I wanted a way to collect this information from a number of servers. I created another CmdLet to retrieve information from two associated classes.
Namespace: root\hpq
Classes: HP_MPFirmware and HP_ManagementProcessor

For full details about the properties in these classes as well as the rest of the HP WBEM classes, download the latest version of the PDF document HP Insight Management WBEM Providers for Microsoft Windows Data Sheet

The Get-HPiLOInformation function

function Get-HPiLOInformation
    Retrieves iLO management controller firmware information
    for HP servers.
    The Get-HPiLOInformation function works through WMI and requires
    that the HP Insight Management WBEM Providers are installed on
    the server that is being quiered.
    .PARAMETER Computername
    The HP server for which the iLO firmware info should be listed.
    This parameter is optional and if the parameter isn't specified
    the command defaults to local machine.
    First positional parameter.
    Lists iLO firmware information for the local machine
    Get-HPiLOInformation SRV-HP-A
    Lists iLO firmware information for server SRV-HP-A
    "SRV-HP-A", "SRV-HP-B", "SRV-HP-C" | Get-HPiLOInformation
    Lists iLO firmware information for three servers
    [Parameter(Mandatory=$false, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true, Position = 1)][string]$Computername=$env:computername


        if ($pscmdlet.ShouldProcess("Retrieve iLO information from server " +$Computername)){
            $MpFirmwares =  Get-WmiObject -Computername $ComputerName -Namespace root\hpq -Query "select * from HP_MPFirmware"
            ForEach ($fw in $MpFirmwares){
                $Mp = Get-WmiObject -Computername $ComputerName -Namespace root\hpq -Query ("ASSOCIATORS OF {HP_MPFirmware.InstanceID='" + $fw.InstanceID + "'} WHERE AssocClass=HP_MPInstalledFirmwareIdentity")

                $OutObject = New-Object System.Object
                $OutObject | Add-Member -type NoteProperty -name ComputerName -value $ComputerName
                $OutObject | Add-Member -type NoteProperty -name ControllerName -value $fw.Name

                Switch ($Mp.HealthState){
                    5 {$stat = "OK"; break}
                    10 {$stat = "Degraded/Warning"; break}
                    20 {$stat = "Major Failure"; break}
                    default {$stat = "Unknown"}
                $OutObject | Add-Member -type NoteProperty -name HealthState -value $stat

                $OutObject | Add-Member -type NoteProperty -name UniqueIdentifier -value $Mp.UniqueIdentifier.Trim()
                $OutObject | Add-Member -type NoteProperty -name Hostname -value $Mp.Hostname
                $OutObject | Add-Member -type NoteProperty -name IPAddress -value $Mp.IPAddress

                Switch ($Mp.NICCondition){
                    2 {$stat = "OK"; break}
                    3 {$stat = "Disabled"; break}
                    4 {$stat = "Not in use"; break}
                    5 {$stat = "Disconnected"; break}
                    6 {$stat = "Failed"; break}
                    default {$stat = "Unknown"}
                $OutObject | Add-Member -type NoteProperty -name NICCondition -value $stat

                $OutObject | Add-Member -type NoteProperty -name FirmwareVersion -value $fw.VersionString
                $OutObject | Add-Member -type NoteProperty -name ReleaseDate -value ($fw.ConvertToDateTime($fw.ReleaseDate))

                Write-Output $OutObject
