Tips for the Optical Autochanger

• If your optical autochanger does not work with Backup, your operating system may not currently include support for the optical autochanger media drive.

• When you create the Backup device names for an optical autochanger, you should use the raw name of the device.

• If you experience a power outage, the optical autochanger loses track of the state of its backup volumes. Issuing the nsrjb -H command may not successfully reset the autochanger. If you see output similar to the following, it means the nsrjb -H command failed to reset the autochanger:

# nsrjb -H
nsrjb: Autochanger error, Invert operation not supported

Use the following procedure to reset the autochanger:

1. Enter the following command, and make a note of the output.

   # nsrjb -H

   This command displays information about the volumes loaded in the drive(s), the volume label(s), and the slots from which the volumes were loaded into the drive(s).

2. Manually unload the volume from the device.

   Consult your autochanger hardware documentation for information on how to do this. The volume ends up in the cartridge access port with the "B" side facing up.

3. Manually reinsert the volume into the cartridge access port, flipping them over so that the "A" side faces up.

4. Use the control panel on the autochanger to reload the volume from the cartridge access port into the slot it originally came from.

5. Reset the autochanger.
