      .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.
