Agreed! You define the path with the server device file (rmtX on aix). On first access tsm will populate the drive with all the specs of the drive (s/n, wwn, etc). You use the wwpn for zoning. Check the switch port for a drive - use the wwn that is logged into the switch.

WWNs are what we used to zone the drives on the SAN. Our zoning tool (Cisco) does not really give you a choice on which name to use. Does that help?

Tsm server 6.2.5, rhel 6.1, ibm 3494 library and ts1120 drives. If I issue a Udevadm info -attribute-walk For all /dev/IBMtapexx devices I get a listing of everything that can be determined about these drives. When defining these drives to tsm, which do I use for the "wwn" parm? Do I use ww_node_name, or ww_port_name? I think it would be ww_port_name, but just checking before I add more drives. On some of them, both are equal, but others the node_name and port_name differ.
