DFSMShsm received an ADDVOL command for a primary volume volser that is not online to the processor receiving the command. DFSMShsm on the receiving processor supporting JES3 has accepted the volume as managed by DFSMShsm and will work with JES3 to cause data set reservation on this volume as a DFSMShsm volume. However, DFSMShsm on the receiving processor does not completely add this volume to DFSMShsm control or select the volume for data set recall. The volume must be online to at least one processor that has an active DFSMShsm and an ADDVOL command must be issued to that processor to complete the addition.
