140 Converting to DFSMSrmm from ASG-ZARA or AutoMedia
4.1.1 How it works
Use ACS routines for scratch pooling based on tape storage group names. Using
ACS processing to set a storage group name overrides all other pool selection
methods. DFSMSrmm provides support for non-system-managed tape and for
system-managed manual tape libraries. This support enables pooling at the
individual volume level. You assign a storage group name to each volume by
using DFSMSrmm TSO subcommands, or by using pooling information that you
define with the DFSMSrmm EDGRMMxx PARMLIB VLPOOL command (see
“Tailoring your EDGRMMxx PARMLIB member” on page 162). DFSMSrmm calls
ACS routines passing environment information, including the pool identified by
DFSMSrmm system
