The jbexercise Command Fails

If the jbexercise command fails, review the following list of suggestions to identify potential problems and their solutions:

• The jbexercise program prompts you for a no-rewind device name (for example, on Solaris, /dev/rmt/0mbn). Verify that you have supplied the correct device pathname for the tape drive. The device name must belong to a tape drive in the autochanger, not the autochanger itself. If you receive the following error message, you did not enter a no-rewind device name:

  device not ready

• Make sure that the tape drive for which you enter the pathname works. Insert a volume into the drive and perform the following tests:

  • Use the tar command to copy a small file to the volume.

  • Verify more extensive operations by issuing the tapeexercise command.

  If these tests fail, the tape drive is not functioning. Contact your hardware vendor for further information on how to configure your tape drive to work with your system.

If none of these suggestions resolve the problem, contact SunSoft Technical Support. You need to provide the information described in "Information to Gather Before You Call Technical Support " and the captured output of the jbexercise, sjiinq, and sjirjc programs. See Appendix B, Command Line Reference Utilities for information on the jbexercise, sjiinq, and sjirjc programs, or refer to the associated man pages for each program.
