Testing the Tape Library Installation

The tape library media changer test program JItest.exe (or ./jitest* depending on platform) is used to test the tape library installation. The test program requires as an argument the media changer device file name created during the installation procedure in the preceding chapter. The example here uses a Windows device name. The only difference between this example and other platforms is the device name which can be /dev/sync_sa0, /dev/rchg/c000t0d0s0, etc. For UNIX and Linux environments, run ./bin/bexenv prior to running the jitest utility.

  1. At the command line, type jitest sync_sa0 (or ./jitest /dev/sync_sa/0 for UNIX). This produces the following output: Please type the command.

  2. Enter the command open to open communications. Sample output follows: 

    Device <<sync_sa0>> is opened.....
do_inquiry().....

==========================================================

    The output lists information pertaining to this particular tape library. An explanation of some of the parameters follows:

    NUM_ARMS

    Number of media changers and the address of the first media changer (FIRST_ARM_ADDR).

    NUM_CARTS

    Number of tape cartridges and the first cartridge (FIRST_CART_ADDR).

    NUM_DRIVES

    Number of tape drives and the first drive (FIRST_DRIVE_ADDR).

    NUM_XPORTS

    Number of CAPs (Cartridge Access Ports) and the first CAP (FIRST_XPORT_ADDR).

    In our example, the address of the first drive is 1030. The second drive therefore has an address of 1031. The same holds for the cartridges. The first cartridge has an address of 0, the second has an address of 1, and so on.

    1. Type setup 0.

    2. Type quit to quit JItest, or type help for other useful commands.

    3. If the media changer accepts these commands without obvious error, the tape library is ready to be configured for use. Proceed to Chapter 37: Overview of Manual Tape Library Configuration for the tape library configuration procedure.
