Function Set-UnityPool {

  <#
      .SYNOPSIS
      Modifies storage pool parameters.
      .DESCRIPTION
      Modifies storage pool parameters.
      You need to have an active session with the array.

      .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 of the pool or Pool Object.
      .PARAMETER NewName
      New name of the pool.
      .PARAMETER Description
      Description of the pool.
      .PARAMETER AddVirtualDisk
      Virtual Disks only with associated parameters to add to the pool. See examples for details.
      .PARAMETER AddraidGroup
      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 -ID 'pool_10' -Description 'Modified description'

      Change the description of the pool with ID 'pool_10'
      .EXAMPLE
      Set-UnityPool -ID 'pool_10' -AddVirtualDisk @{'id'='vdisk_1';'tier'='Performance'}

      Add a virtual disk 'vdisk_1' to the pool with ID 'pool_10'
      .EXAMPLE
      Set-UnityPool -ID 'pool_10' -AddraidGroup @{"id"='dg_8';"numDisks"= 8; 'raidType'='RAID6'; 'stripeWidth'='8'}

      Add a raid group 'dg_8' to the pool with ID 'pool_10'
