Function New-UnityLUN { <# .SYNOPSIS Creates a Unity block LUN. .DESCRIPTION Creates a Unity 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 LUN unique to the system. .PARAMETER Pool Pool ID .PARAMETER Description Description of the LUN. .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 compatible arrays .PARAMETER isThinEnabled Is Thin enabled on LUN ? (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 settings for the LUN, as defined by the snapScheduleParameters. .PARAMETER isSnapSchedulePaused Indicates whether the assigned snapshot schedule is paused. .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 New-UnityLUN -Name 'DATASTORE01' -Pool 'pool_1' -Size 10GB -host 'Host_12' -accessMask 'Production' Create LUN named 'LUN01' on pool 'pool_1' and with a size of '10GB', grant production access to 'Host_12' #> [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=$True,HelpMessage = 'LUN Name')] [String[]]$Name, [Parameter(Mandatory = $false,HelpMessage = 'LUN Description')] [String]$Description, # lunParameters [Parameter(Mandatory = $true,HelpMessage = 'LUN Pool ID')] [String]$Pool, [Parameter(Mandatory = $true,HelpMessage = 'LUN Size in Bytes')] [uint64]$Size, [Parameter(Mandatory = $false,HelpMessage = 'Host to grant access to LUN')] [String[]]$host, [Parameter(Mandatory = $false,HelpMessage = 'Host access mask')] [HostLUNAccessEnum]$accessMask = 'Production', [Parameter(Mandatory = $false,HelpMessage = 'Is Thin enabled on LUN ?
