Function Set-UnityvCenter {

  <#
      .SYNOPSIS
      Modifies an existing vCenter and optionally discovers any ESXi host managed by that vCenter.
      .DESCRIPTION
      Modifies vCenter servers on the network and optionnaly create a host configuration for multiple ESXi hosts managed by a single vCenter server.
      You can't modify vCenter parameters and import hosts in the same command.
      For any discovered vCenters, you can enable or disable access for any ESXi host managed by the vCenter.
      After you associate a vCenter server configuration with a VMware datastore, the datastore is available to any ESXi hosts associated with the vCenter host configuration.
      The vCenter credentials are stored in the storage system.
      You need to have an active session with the array.
