  <refsect1><title>DESCRIPTION</title>
    <para>
      <emphasis remap='B'>Amdevcheck</emphasis> provides a way to check that a
      particular Amanda device is accessible, whether or not it contains a volume,
      and whether or not that volume is labeled. Some devices can't distinguish
      between all of these cases; a missing volume and an unlabeled volume might
      generate the same error code, for example. In those cases, this tool
      reports all possible causes of the error. Optionally this tools lists the
      properties for the device.

    <para><emphasis remap='B'>amdevcheck</emphasis> exit with code 0 if the device is working of if it get an expected error, look at the MESSAGE line for the error. It exit with code 1 if it get an unexpected error.</para>
    <para><emphasis remap='B'>Amdevcheck</emphasis> returns one or more of the following lines. If multiple lines appear, then at least one, but not necessarily all of
the messages apply.  This situation can occur when working with hardware or
operating systems which cannot distinguish, for example, between a
malfunctioning drive and a functional but unloaded drive.</para>
