Subpooling is not required, but is supported by CA Vtape. If you have defined subpools in your Tape Management System for the workloads that will be moved to CA Vtape, those subpool definitions must be duplicated in the subpool definitions in the CA Vtape VTPOOLS parmlib member.
Note: Multiple pool definitions are not supported under JES3. Under JES3 only one volume pool can be defined.
Up to eight subpools can be defined. If the workloads that will be moved to CA Vtape currently use more than eight subpools, then you will need to consolidate your Tape Management System subpool definitions to reduce the number of subpools to eight or less. Consult your Tape Management System manuals to determine how to modify your subpool definitions.
If you have licensed the CA Vtape Peer-To-Peer Option, then you will need to reduce the number of subpools defined to seven or less. Subpool eight is reserved for the Peer-To-Peer Option.
Note: How to define the subpools is covered in the chapter "The Parameter Library (PARMLIB)."
