<p>The Create Device Description (Media Library) (CRTDEVMLB) command creates a device description for a media library device.
</p>
<p>Initially, all tape drive resources associated with this device description are allocated for use by this system. To change the allocation of drive resources within a tape library, use the Work with Media Library Status (WRKMLBSTS) command or the Vary Configuration (VRYCFG) command.
</p>
<p>
<b>Note: </b>Allocating drives is only allowed when DEVCLS(*TAP) is specified.
</p>
<p>More information about using this command is in the Local Device Configuration book, SC41-5121.
</p>
<p><b>Restriction:</b> The user of this command must have *IOSYSCFG authority.
