Single Library With Multiple Hosts - EMC DL3D 1500 Administrator's Manual

Configuring and Managing Virtual Tape Libraries

Single library with multiple hosts

You must use the DL3D to create different groups for each host so
that multiple hosts can use the same devices. A group consists of
exactly one host, one target, and one or more devices. The DL3D does
not permit multiple hosts to access the same group.
