CTxAdmTools provide a handy tool for removing HP’s Proliant Support pack. I’ve used it on a number of occasions typically when P2V’ing HP servers, and it’s a great time saver. Once the server is virtualized you’ll want to remove the PSP as it may cause issues further down the line and it’s simply software and drivers that you won’t need on the system any more. I’ve seen people recommend removing the PSP prior to the P2V process, but I believe it’s best to keep the source server ‘as is’ if you need to backout of the procedure.
