function Initialize-PSDCVhdDisk { <# .SYNOPSIS Initialize-PSDCVhdDisk initialized the VHD .DESCRIPTION Initialize-PSDCVhdDisk will initialize the VHD. It mounts the disk, creates a volume, creates the partition and sets it to active .PARAMETER Path The path to the VHD .PARAMETER Credential Allows you to use credentials for creating items in other locations To use: $scred = Get-Credential, then pass $scred object to the -Credential parameter. .PARAMETER PartitionStyle A partition can either be initialized as MBR or as GPT. GPT is the default. .PARAMETER AllocationUnitSize Set the allocation unit size for the disk. By default it's 64 KB because that's what SQL Server tends to write most of the time. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .NOTES Author: Sander Stad (@sqlstad, sqlstad.nl) Website: https://psdatabaseclone.org Copyright: (C) Sander Stad, sander@sqlstad.nl License: MIT https://opensource.org/licenses/MIT .LINK https://psdatabaseclone.org/ .EXAMPLE Initialize-PSDCVhdDisk -Path $path Initialize the disk pointing to the path with all default settings .EXAMPLE Initialize-PSDCVhdDisk -Path $path -AllocationUnitSize 4KB Initialize the disk and format the partition with a 4Kb allocation unit size #> [CmdLetBinding(SupportsShouldProcess = $true)] Param( [Parameter(Mandatory = $true)] [string]$Path, [System.Management.Automation.PSCredential] $Credential, [ValidateSet('GPT', 'MBR')] [string]$PartitionStyle = 'GPT', [int]$AllocationUnitSize = 64KB, [switch]$EnableException ) begin { # Check the path to the vhd if (-not (Test-Path -Path $Path -Credential $Credential)) { Stop-PSFFunction -Message "Vhd path cannot be found" -Target $Path -Continue } } process { # Test if there are any errors if (Test-PSFFunctionInterrupt) { return } # Get all the disks $disks = Get-Disk | Select-Object Number, Location, OperationalStatus # Check if disk is already mounted if ($disks.Location -contains $Path) { Write-PSFMessage -Message "Vhd is already mounted" -Level Warning # retrieve the specific disk $disk = $disks | Where-Object {$_.Location -eq $Path} } else { if ($PSCmdlet.ShouldProcess($disk, "Mounting disk")) { # Mount the vhd try { Write-PSFMessage -Message "Mounting disk $disk" -Level Verbose $disk = Mount-VHD -Path $Path -PassThru | Get-Disk } catch { Stop-PSFFunction -Message "Couldn't mount vhd" -Target $Path -ErrorRecord $_ -Continue } } } if ($PSCmdlet.ShouldProcess($disk, "Initializing disk")) { # Check if the disk is already initialized if ($disk.PartitionStyle -eq 'RAW') { try { Write-PSFMessage -Message "Initializing disk $disk" -Level Verbose $disk | Initialize-Disk -PartitionStyle $PartitionStyle -Confirm:$false } catch { Stop-PSFFunction -Message "Couldn't initialize disk" -Target $disk -ErrorRecord $_ -Continue } } } if ($PSCmdlet.ShouldProcess($disk, "Partitioning volume")) { # Create the partition, set the drive letter and format the volume try { $volume = Get-Disk -Number $disk.Number | New-Partition -UseMaximumSize | Format-Volume -FileSystem NTFS -NewFileSystemLabel "PSDatabaseClone" -AllocationUnitSize $AllocationUnitSize -Confirm:$false } catch { # Dismount the drive Dismount-VHD -Path $Path Stop-PSFFunction -Message "Couldn't create the partition" -Target $disk -ErrorRecord $_ -Continue } } # Add the results to the custom object [PSCustomObject]@{ Disk = $disk Partition = (Get-Partition -Disk $disk) Volume = $volume } } end { # Test if there are any errors if (Test-PSFFunctionInterrupt) { return } Write-PSFMessage -Message "Finished initializing disk(s)" -Level Verbose } } |
