Function Set-UnityVMwareLUN { <# .SYNOPSIS Modifies VMware block LUN parameters. .DESCRIPTION Modifies VMware block LUN parameters. 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 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. .PARAMETER ID ID or Object. .PARAMETER Name New name of the VMware VMFS datastore unique to the system. .PARAMETER Description New description of the VMware VMFS datastore. .PARAMETER Size New LUN size. The size parameter can be greater than the current LUN size in this case the LUN is expanded. .PARAMETER snapSchedule Snapshot schedule settings for the VMware VMFS datastore, as defined by the snapScheduleParameters. .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 append Add new host access to the existing configuration. .PARAMETER snapSchedule Snapshot schedule assigned to the storage resource .PARAMETER isSnapSchedulePaused Indicates whether the assigned snapshot schedule is paused. .EXAMPLE Set-UnityVMwareLUN -ID 'sv_78' -Description 'Modified description' Change the description of the VMware bock LUN with ID 'sv_78'. .EXAMPLE Set-UnityVMwareLUN -ID 'sv_78' -Pool 'pool_14' -host 'Host_12' -accessMask 'Production' -Append Grant 'production' access to host 'Host_12' to VMware bock LUN with ID 'sv_78'. #> [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 ID or LUN Object')] $ID, [Parameter(Mandatory = $false,HelpMessage = 'New Name of the LUN')] [String]$Name, [Parameter(Mandatory = $false,HelpMessage = 'New LUN Description')] [String]$Description, [Parameter(Mandatory = $false,HelpMessage = 'New LUN Size in Bytes')] [uint64]$Size, [Parameter(Mandatory = $false,HelpMessage = 'ID of a protection schedule to apply to the storage resource')] [String]$snapSchedule, [Parameter(Mandatory = $false,HelpMessage = 'Host to grant access to LUN')] [String[]]$host, [Parameter(Mandatory = $false,HelpMessage = 'Append Host access to existing configuration')] [Switch]$append, [Parameter(Mandatory = $false,HelpMessage = 'Host access mask')] [HostLUNAccessEnum]$accessMask = 'Production', [Parameter(Mandatory = $false,HelpMessage = 'Is assigned snapshot schedule is paused ?
