3. Add the Tape Library to the Enterprise
- Launch the management console. 
- Open the Configure Devices window by clicking the Configure tab at the top of the window, then selecting Devices from the task pane. 
- Select the Enterprise, then click Add Tape Library. 
- Complete the active fields in the Add Tape Library dialog. \ - Tape Library Name - Enter a name, up to 13 alphanumeric characters, for the tape library, for example SALES_LIB. Tape library names must be unique. - Storage Area Network - Specify whether devices in the tape library are connected to a SAN. As stated, the best practice is to always select SAN, even when there is only one device path (i.e. only one host with drives). - Tape Library Type - Select a tape library type, for example EXB210, from the menu. - Controller Node - Specify your chosen controller node. As stated, the recommended controller node is the master server. - Controller ID - Enter the complete path and name to the media changer ID on the controller node. This is the value noted in step 3. For example, \\.\Changer12, \\.\sync_sa5, or dev/sg7. - Device Type - Select a device type, for example LTO, from the menu. All devices in a tape library must be the same type. - Using Slot - Enter the starting and ending slot numbers to use for media volumes. For example, entering 1 and 11 tells DPX that slot numbers 1 through 11 are reserved for DPX media volumes. - Cleaning Slot - Enter the slots used for the cleaning media. If there is only one cleaning slot, enter the slot number twice; for example, 0 through 0 indicates that slot number 0 contains a cleaning media. If there is no cleaning slot, enter -1 in each field. - Cleaning Threshold - Enter the number of times a drive can be used before it is cleaned. - Comment - Enter an optional comment up to 48 characters. 
- Click Add. The new tape library name appears in the device resource tree and is indicated by the selection check box.
