Function New-UnityVMwareLUN { <# .SYNOPSIS Creates a Unity VMware block LUN. .DESCRIPTION Creates a Unity VMware block LUN. 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 Name Name of the VMware VMFS datastore unique to the system. .PARAMETER Pool Pool ID .PARAMETER Description Description of the VMware VMFS datastore. .PARAMETER Size LUN Size. .PARAMETER fastVPParameters FAST VP settings for the storage resource .PARAMETER isCompressionEnabled Indicates whether to enable inline compression for the LUN. Default is True on supported arrays .PARAMETER isThinEnabled Is Thin enabled? (Default is true) .PARAMETER host List of host to grant access to LUN. .PARAMETER accessMask Host access mask. Might be: - NoAccess: No access. - Production: Access to production LUNs only. - Snapshot: Access to LUN snapshots only. - Both: Access to both production LUNs and their snapshots. .PARAMETER snapSchedule Snapshot schedule assigned to the storage resource .PARAMETER isSnapSchedulePaused Indicates whether the assigned snapshot schedule is paused. .EXAMPLE New-UnityVMwareLUN -Name 'DATASTORE01' -Pool 'pool_1' -Size 10GB -host 'Host_12' -accessMask 'Production' Create LUN named 'DATASTORE01' on pool 'pool_1' and with a size of '10GB', grant production access to 'Host_12' .EXAMPLE for($i=1; $i -le 10; $i++){New-UnityVMwareLUN -Name "DATASTORE0$i" -Size 2TB -Pool 'pool_1' -host (Get-UnityHost).id} Create 10 datastores on pool 'pool_1' and with a size of '2TB', grant production access to all existing hosts. #> [CmdletBinding(SupportsShouldProcess = $True,ConfirmImpact = 'High')] Param ( [Parameter(Mandatory = $false,HelpMessage = 'EMC Unity Session')] $session = ($global:DefaultUnitySession | where-object {$_.IsConnected -eq $true}), [Parameter(Mandatory = $true,Position = 0,ValueFromPipeline=$True,ValueFromPipelinebyPropertyName=$True,HelpMessage = 'VMware LUN Name')] [String[]]$Name, [Parameter(Mandatory = $false,HelpMessage = 'VMware LUN Description')] [String]$Description, # lunParameters [Parameter(Mandatory = $true,HelpMessage = 'VMware LUN Pool ID')] [String]$Pool, [Parameter(Mandatory = $true,HelpMessage = 'VMware LUN Size in Bytes')] [uint64]$Size, [Parameter(Mandatory = $false,HelpMessage = 'Host to grant access to VMware LUN')] [String[]]$host, [Parameter(Mandatory = $false,HelpMessage = 'Host access mask')] [HostLUNAccessEnum]$accessMask = 'Production', [Parameter(Mandatory = $false,HelpMessage = 'Is Thin enabled on VMware LUN ?
