Configure tape libraries

After you have set up the tape library and connected it to your system, the iSeries™ server automatically configures it.

The system creates a device description named TAPMLB xx, where xx is the next available device description number, and configures any associated tape resources (MLBRSC) and tape device descriptions (TAP xx). The system creates tape device descriptions for each tape resource. These tape device descriptions are used for stand-alone operations when the tape library is in stand-alone, auto, or manual mode, and for service.

Note: A tape device description is required for each device resource for the tape library device to operate properly.
Note: Drives with different capabilities within the same tape library must either be connected to separate IOAs, or the tape library must be partitioned so that each kind of drive is in a separate logical partition. There will be a separate tape library device description created for each kind of tape device within the tape library.

Configure a tape library other than a 3494 tape library

To prepare your tape library for use complete the following procedure:

  1. Ensure that the tape library is set to random mode. If it is not, use the device panel to set it to random mode.
  2. At the character-based interface, type WRKMLBSTS and press Enter. This command allows you to work with the status of the device.
  3. In the option field next to each resource, select option 4 (ALLOCATE) or option 5 (UNPROTECTED) and press Enter. This step makes the resource available to the tape library.
  4. Add cartridges to the tape library. See the documentation for your media management application, or the topic Make cartridges available to the tape library inventory for more information.

Configure a 3494 tape library

The 3494 tape library supports connections to multiple 3490, 3590, and 3592 tape devices within the same physical unit. When the iSeries server configures these devices, it creates a unique device description for each kind of tape device in the physical 3494 tape library. When any of these device descriptions is varied on, all devices of that type within that 3494 tape library will be associated with it.

To prepare the 3494 tape library ready for use complete the following procedure:

  1. Ensure that the tape library is set to automated mode. If it is not, use the device panel to set it to automated mode.
  2. Create a data link for a 3494 tape library for the 3494 tape library. Creating a data link defines the communication line associated with the tape library.
  3. At a command line, type WRKMLBSTS and press Enter. This allows you to work with the status of the device.
  4. In the option field next to each resource, enter option 4 (ALLOCATE) or option 5 (UNPROTECTED) and press Enter. These options make the resource available to the tape library.
  5. Add cartridges to the tape library. See the documentation for your media management application or the topic Add cartridges to the tape library inventory for more information.
