Function Set-UnityPool { <# .SYNOPSIS Modifies storage pool parameters. .DESCRIPTION Modifies storage pool 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 Name Name of the pool or Pool Object. .PARAMETER NewName New name of the pool. .PARAMETER Description Description of the pool. .PARAMETER virtualDisk Virtual Disks only with associated parameters to add to the pool. See examples for details. .PARAMETER raidGroup Parameters to add RAID groups to the pool (disk group, number of disks, RAID level, stripe length). See examples for details. .PARAMETER isFASTCacheEnabled Specify whether to enable FAST Cache on the storage pool. .PARAMETER isFASTVpScheduleEnabled Specify whether to enable scheduled data relocations for the pool. .PARAMETER alertThreshold For thin provisioning, specify the threshold, as a percentage, when the system will alert on the amount of subscription space used. .PARAMETER isHarvestEnabled Indicate whether the system should check the pool full high water mark for autodelete. .PARAMETER poolSpaceHarvestHighThreshold Specify the pool full high watermark for the storage pool. .PARAMETER poolSpaceHarvestLowThreshold Specify the pool full low watermark for the storage pool. .PARAMETER isSnapHarvestEnabled Indicate whether the system should check the snapshot space used high water mark for auto-delete. .PARAMETER snapSpaceHarvestHighThreshold Specify the snapshot space used high watermark to trigger auto-delete on the storage pool. .PARAMETER snapSpaceHarvestLowThreshold Specify the snapshot space used low watermark to trigger auto-delete on the storage pool. .EXAMPLE Set-UnityPool -Name 'Pool01' -Description 'Modified description' Change the description of the Pool named Pool01 .EXAMPLE Set-UnityPool -Name 'Pool01' -AddVirtualDisk @{'id'='vdisk_1';'tier'='Performance'} Add a virtual disk 'vdisk_1' to the pool named 'Pool01' .EXAMPLE Set-UnityPool -Name 'Pool01' -AddraidGroup @{"id"='dg_8';"numDisks"= 8; 'raidType'='RAID6'; 'stripeWidth'='8'} Add a raid group 'dg_8' to the pool named 'Pool01' #> [CmdletBinding(SupportsShouldProcess = $True,ConfirmImpact = 'High',DefaultParameterSetName="RaidGroup")] Param ( #Default Parameters [Parameter(Mandatory = $false,HelpMessage = 'EMC Unity Session')] $session = ($global:DefaultUnitySession | where-object {$_.IsConnected -eq $true}), #UnityPool [Parameter(Mandatory = $true,Position = 0,ValueFromPipeline=$True,ValueFromPipelinebyPropertyName=$True,HelpMessage = 'Pool Name or Pool Object')] $Name, [Parameter(Mandatory = $false,HelpMessage = 'New Name of the Pool')] [String]$NewName, [Parameter(Mandatory = $false,HelpMessage = 'Pool Description')] [String]$Description, [Parameter(Mandatory = $false,ParameterSetName="VirtualDisk",HelpMessage = 'Parameters to add virtual disks to the pools')] [array]$AddVirtualDisk, [Parameter(Mandatory = $false,ParameterSetName="RaidGroup",HelpMessage = 'Parameters to add RAID groups to the pool (disk group, number of disks, RAID level, stripe length)')] [array]$AddraidGroup, [Parameter(Mandatory = $false,HelpMessage = 'Threshold at which the system will generate alerts about the free space in the pool')] [Int]$alertThreshold, [Parameter(Mandatory = $false,HelpMessage = 'Pool used space high threshold at which the system will automatically starts to delete snapshots in the pool, specified as a percentage with .01% granularity')] [Long]$poolSpaceHarvestHighThreshold, [Parameter(Mandatory = $false,HelpMessage = 'Pool used space low threshold under which the system will automatically stop deletion of snapshots in the pool, specified as a percentage with .01% granularity')] [Long]$poolSpaceHarvestLowThreshold, [Parameter(Mandatory = $false,HelpMessage = 'Snapshot used space high threshold at which the system automatically starts to delete snapshots in the pool, specified as a percentage with .01% granularity.')] [Long]$snapSpaceHarvestHighThreshold, [Parameter(Mandatory = $false,HelpMessage = 'Snapshot used space low threshold below which the system will stop automatically deleting snapshots in the pool, specified as a percentage with .01% granularity.')] [Long]$snapSpaceHarvestLowThreshold, [Parameter(Mandatory = $false,HelpMessage = 'Is Harvest Enabled ?')] [Bool]$isHarvestEnabled, [Parameter(Mandatory = $false,HelpMessage = 'Is Snapshot Harvest Enabled')] [Bool]$isSnapHarvestEnabled, [Parameter(Mandatory = $false,HelpMessage = 'Is FAST Cache Enabled ?')] [Bool]$isFASTCacheEnabled, [Parameter(Mandatory = $false,HelpMessage = 'Is FAST Vp Schedule Enabled ?
