|
<div><p>This topic provides information on operational guidelines by device
|
||
|
|
type for optical library data servers and CD-ROM, DVD-ROM, and DVD-RAM standalone
|
||
|
|
optical drive devices.</p>
|
||
|
|
<p><strong>Optical library dataservers</strong></p>
|
||
|
|
<ul><li>You cannot use the default value, *MOUNTED, for the volume identifier.</li>
|
||
|
|
<li>Volumes that are provided in a volume list must all be in the same library
|
||
|
|
device.</li>
|
||
|
|
<li>A single save data file may span several volumes in a volume list.</li>
|
||
|
|
<li>For HPOFS formatted media, any volume used in a volume list becomes unusable
|
||
|
|
by any save or restore operation other than the operation originally processing
|
||
|
|
the volume list. <p>For example:</p>
|
||
|
|
<ul><li>Save command A writes save data fileA to volume volA.</li>
|
||
|
|
<li>Save command B writes save data fileB to volume list: volC, volB, volA.</li>
|
||
|
|
<li>Restore command A will not be able to restore from fileA on volume volA.</li>
|
||
|
|
<li>Restore command B will be able to restore from fileB on the volume list:
|
||
|
|
volC, volB, volA.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p><strong>CD-ROM and DVD-ROM standalone optical drive devices</strong></p>
|
||
|
|
<ul><li>CD-ROM and DVD-ROM are read-only devices. The system does not support
|
||
|
|
save commands for these devices.</li>
|
||
|
|
<li>Save files cannot span multiple CD-ROM or DVD-ROM media that contain ISO
|
||
|
|
9660 media format.</li>
|
||
|
|
<li>You can specify the default value, *MOUNTED, for the volume identifier.
|
||
|
|
It will process the optical volume currently in the specified stand-alone
|
||
|
|
device.</li>
|
||
|
|
</ul>
|
||
|
|
<p><strong>DVD-RAM standalone optical drive devices</strong></p>
|
||
|
|
<ul><li>DVD-RAM devices are read and write devices. Save and restore commands
|
||
|
|
are supported for DVD-RAM devices.</li>
|
||
|
|
<li>You can specify the default value, *MOUNTED, for the volume identifier.
|
||
|
|
It will process the optical volume currently in the specified stand-alone
|
||
|
|
device.</li>
|
||
|
|
<li>Multiple save data files may span several volumes in a specified DVD_RAM
|
||
|
|
volume list.</li>
|
||
|
|
</ul>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> Software compression and decompression might increase
|
||
|
|
the save and restore times. It uses considerable processing resources which
|

may affect the overall system performance.</div>
