<h1 class="topictitle1">Volume identifiers</h1>
|

<div><p>Loading a CD-ROM or DVD media into a drive causes automatic reading
|
||
|
|
of the information from the media. Part of this information is the volume
|
||
|
|
identifier. </p>
|
||
|
|
<p>The volume identifier is a name that was given to the CD-ROM or DVD-ROM
|
||
|
|
when it was mastered. The identifier is also the name that is given to the
|
||
|
|
DVD-RAM media when it was initialized. Depending on the media format, the
|
||
|
|
volume identifier can be up to 32 characters in length. On the iSeries™ server,
|
||
|
|
applications accessing data from the CD-ROM or DVD often refer to it by its
|
||
|
|
volume identifier. For example, a CD-ROM volume identifier might be <samp class="codeph">VOLID01</samp>.</p>
|
||
|
|
<p>Applications that need to access file data from any optical media need
|
||
|
|
to refer to the volume identifier. For example, you could write a C program
|
||
|
|
to use the integrated file system APIs to read file <samp class="codeph">/DIR1/FILE</samp> on
|
||
|
|
the optical volume <samp class="codeph">VOLID01.</samp> In this case, the application
|
||
|
|
would specify path <samp class="codeph">/QOPT/VOLID01/DIR1/FILE</samp> on the open request.</p>
