Establishing a Guest LAN Owner

The OWNERid operand determines both the owner of the LAN and the lifetime of the LAN. The OWNERid may assume values:
*
the owner is invoker of the DEFINE LAN command (this is the default).
ownerid
a z/VM® user that owns the LAN.
SYSTEM
the LAN is to be a persistent LAN.

Both the LAN name and its owner uniquely identify a guest LAN (this means you may define two distinct LANs, provided they are owned by different z/VM users).
