function Get-vSANInfo { <# .SYNOPSIS Get basic vSAN Cluster information .DESCRIPTION Will get inventory information for a vSAN Cluster The following is gathered: vSAN Cluster Name, Cluster Type, Disk Claim Mode, Dedupe & Compression Enabled, Stretched Cluster Enabled, Oldest Disk Format Version, Total Disks, Total Disk Groups, vSAN Capacity GB .NOTES Author : Graham Barker - @VirtualG_UK Contributor: Edgar Sanchez - @edmsanchez13 Contributor: Ariel Sanchez - @arielsanchezmor .Link https://github.com/arielsanchezmora/vDocumentation .INPUTS No inputs required .OUTPUTS CSV file Excel fil .PARAMETER cluster The name(s) of the vSphere Cluster(s) .EXAMPLE Get-vSANInfo -cluster production-cluster .PARAMETER ExportCSV Switch to export all data to CSV file. File is saved to the current user directory from where the script was executed. Use -folderPath parameter to specify a alternate location .EXAMPLE Get-vSANInfo -cluster production-cluster -ExportCSV .PARAMETER ExportExcel Switch to export all data to Excel file (No need to have Excel Installed). This relies on ImportExcel Module to be installed. ImportExcel Module can be installed directly from the PowerShell Gallery. See https://github.com/dfinke/ImportExcel for more information File is saved to the current user directory from where the script was executed. Use -folderPath parameter to specify a alternate location .EXAMPLE Get-vSANInfo -cluster production-cluster -ExportExcel .PARAMETER folderPath Specify an alternate folder path where the exported data should be saved. .EXAMPLE Get-vSANInfo -ExportExcel -folderPath C:\temp .PARAMETER PassThru Switch to return object to command line .EXAMPLE Get-vSANInfo -cluster production-cluster #> <# ----------------------------------------------------------[Declarations]---------------------------------------------------------- #> [CmdletBinding()] param ( $cluster, [switch]$ExportCSV, [switch]$ExportExcel, [switch]$PassThru, $folderPath ) #$hardwareCollection = @() $configurationCollection = @() $skipCollection = @() $vSANClusterList = @() $returnCollection = @() $date = Get-Date -format s $date = $date -replace ":", "-" $dStore = 0; $outputFile = "vsan-info" + $date <# ----------------------------------------------------------[Execution]---------------------------------------------------------- #> <# Query PowerCLI and vDocumentation versions if running Verbose #> if ($VerbosePreference -eq "continue") { Write-Verbose -Message ((Get-Date -Format G) + "`tPowerCLI Version:") Get-Module -Name VMware.* | Select-Object -Property Name, Version | Format-Table -AutoSize Write-Verbose -Message ((Get-Date -Format G) + "`tvDocumentation Version:") Get-Module -Name vDocumentation | Select-Object -Property Name, Version | Format-Table -AutoSize } #END if <# Check for an active connection to a VIServer needs to be vCenter Server 6.5+ #> Write-Verbose -Message ((Get-Date -Format G) + "`tValidate connection to a vCenter server and that it's running at least v6.5.0") if ($Global:DefaultViServers.Count -gt 0 -and $Global:DefaultViServers.Version -ge "6.5.0") { $vCenterVersion = $Global:DefaultViServers.Version Write-Host "`tConnected to vCenter: $Global:DefaultViServers, v$vCenterVersion" -ForegroundColor Green } else { Write-Error -Message "You must be connected to a vCenter Server running at least v6.5.0 server before running this Cmdlet." break } #END if/else <# Validate parameter (-cluster) and gather cluster list. #> Write-Verbose -Message ((Get-Date -Format G) + "`tValidate parameters used") if ([string]::IsNullOrWhiteSpace($cluster) ) { Write-Verbose -Message ((Get-Date -Format G) + "`tA parameter (-cluster) was not specified.
