You can use DFSMSrmm EDGRMMxx VLPOOL command operands to define pool of volumes and to set installation-defined policies for the volumes in the pool. You can define pools based on criteria like:

• Systems or subsets of systems
• z/OS or VM usage
• Use of rack pools to hold foreign tapes
• Media names your installation defines, like 3480, TAPE, CASSETTE
• SMS storage group names
• Release actions for volumes in a pool
