The server uses alias names to identify tape and optical disk devices to the Tivoli Storage Manager device driver. Device names for the Tivoli Storage Manager device driver differ from device names for the Windows device driver. For example, an automated library device might be known as LB0.0.0.1 to the Tivoli Storage Manager device driver and as LIB01 to the Windows device driver.
If you use the Device Configuration Wizard to initially configure devices, the wizard automatically provides the appropriate device name. However, if you configure devices by using Tivoli Storage Manager commands, you must provide the device names as parameters to the DEFINE PATH command. If you modify device driver control, you may need to provide alias name information in the Device Exclude List. The names can be either:
Alias names replace the real device names in Tivoli Storage Manager commands and screens. The Tivoli Storage Manager device driver communicates with devices by using the alias names. See Obtaining Device Alias Names.
Alias names appear in the form mtx.y.z.n or lbx.y.z.n or opx.y.z.n, where:
mt3 (Tape drive at SCSI ID 3, LUN 0, bus 0, port 0)
mt5.0.0.1 (Tape drive at SCSI ID 5, LUN 0, bus 0, port 1)
lb4.1 (Library at SCSI ID 4, LUN 1, bus 0, port 0)
op4 (Optical drive at SCSI ID 4, LUN 0, bus 0, port 0)
If you use the Tivoli Storage Manager Device Configuration Wizard to initially configure devices, this step is unnecessary because the wizard gathers information about the SCSI Target IDs, logical unit numbers, bus numbers, and SCSI port numbers required for the alias names. However, if you add devices using Tivoli Storage Manager commands, you must provide the information in the DEFINE PATH command. To determine the SCSI properties for a device:
