Tivoli Storage Manager for Windows Administrator's Guide


Device Alias Names for Tivoli Storage Manager

TSM uses alias names to identify tape and optical disk devices to the TSM device driver. Device names for the TSM 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 TSM device driver and as LIB01 to the Windows device driver.

Administrators using the Device Configuration Wizard to initially configure devices need not be concerned with device alias names because the wizard automatically provides the device name in the form TSM requires. However, administrators configuring devices using TSM commands must provide the device names as parameters to the DEFINE DRIVE command. Administrators modifying device driver control may need to provide alias name information in the Device Exclude List. The names can be either:

Obtaining Alias Names for Devices describes the procedure for using the server utilities to obtain TSM device names.

Device Alias Names for TSM Commands

Alias names identify TSM devices and are required when configuring devices using TSM commands. Alias names replace the real device names in TSM commands and screens. The TSM device driver communicates with devices by using the alias names. See "Obtaining Alias Names for Devices".

Alias names appear in the form mtx.y.z.n or lbx.y.z.n or opx.y.z.n, where:

mt
Indicates the device is a tape device. For example:

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)

lb
Indicates the device is the controller for an automated library device. For example:

lb4.1 (Library at SCSI ID 4, LUN 1, bus 0, port 0)

op
Indicates the device is an optical device. For example:

op4 (Optical drive at SCSI ID 4, LUN 0, bus 0, port 0)

x
Indicates the SCSI ID for the targeted device

y
Indicates the logical unit number (LUN) for the targeted device

z
Indicates the bus number supported by the adapter device driver

n
Indicates the port number for the SCSI adapter device driver

Note:
Alias names can be abbreviated when the trailing numbers are zeros.
