VMAX Mass storage cleanup before decomissioning

Hi All, We have two VMAX-40K which are part of replication to each other. So currently there is a single DG and RDFG in the stopped state and I have removed MVs and zoning just to ensure there is no host access. Now the next task is to delete all the different devices (Thick, thin, AS400 emulation, meta LUNs), IGs and submit a decommissioning request. I do not want to go through each and every device doing unmap, unbind, meta remove, and all other steps that we usually do while reclaiming storage. Is there any utility available that can delete all these devices or if we submit a data clear request then this would be taken care of with Totalclear script?
