If you're SAN connected, Q SAN on the client supplies the device name for each
path.

This may be a clue, the drive is accessed directly by the library
client. All the library server does is verify the label. After that,
the device is opened by the client. This is the reason the paths
(defined on the library server) must be correct for the library
client. So if a drive called drive4 is \\.\tape4 on the server and \\.
\tape1 on the client, there must be a path, defined on the server,
from your client to drive4 via device \\.\tape1
