You need to have an active session with the array. .NOTES Written by Erwan Quelin under MIT licence - https://github.com/equelin/Unity-Powershell/blob/master/LICENSE .LINK https://github.com/equelin/Unity-Powershell .PARAMETER Session Specify an UnitySession Object. .PARAMETER ID ID of the snapshot or snapshot Object. ID need to be surounded by quote like this '171798691854'. .PARAMETER Confirm If the value is $true, indicates that the cmdlet asks for confirmation before running. If the value is $false, the cmdlet runs without asking for user confirmation. .PARAMETER WhatIf Indicate that the cmdlet is run only to display the changes that would be made and actually no objects are modified. .EXAMPLE Remove-UnitySnap -ID '171798691854' Delete the snapshot with ID '171798691854' .EXAMPLE Get-UnitySnap | Remove-UnitySnap Delete all existing snapshots. #> [CmdletBinding(SupportsShouldProcess = $True,ConfirmImpact = 'High')] Param ( [Parameter(Mandatory = $false,HelpMessage = 'EMC Unity Session')] [UnitySession[]]$session = ($global:DefaultUnitySession | where-object {$_.IsConnected -eq $true}), [Parameter(Mandatory = $true,Position = 0,ValueFromPipeline=$True,ValueFromPipelinebyPropertyName=$True,HelpMessage = 'snapshot ID or snapshot Object')] [Object[]]$ID ) Begin { Write-Verbose "Executing function: $($MyInvocation.MyCommand)" # Variables $URI = '/api/instances/snap/<id>' $Type = 'snapshot' $TypeName = 'UnitySnap' $StatusCode = 204 } Process { Foreach ($sess in $session) { Write-Verbose "Processing Session: $($sess.Server) with SessionId: $($sess.SessionId)" If ($Sess.TestConnection()) { Foreach ($i in $ID) { #Snap ID are normally integers.
