<h1 class="topictitle1">CL command support for media formats</h1>
<div><p>This topic provides information on using i5/OS™ commands to save and restore data
and some of the restrictions for the ISO 9660, High Performance Optical File
System (HPOFS), and universal disk format (UDF) media formats.</p>
<div class="p"><dl><dt class="dlterm">ISO 9660</dt>
<dd>You can use i5/OS restore
commands to restore data from ISO 9660 media. This is true only when the media
was correctly mastered from a save image on tape. There are some restrictions
on which optical commands are supported for ISO 9660 media.</dd>
</dl>
<dl><dt class="dlterm">HPOFS</dt>
<dd>i5/OS save
and restore commands can be used to save and restore data on HPOFS optical
media. Refer to Appendix B, “Optical Save and Restore,” on page 129 for more
information about save and restore to HPOFS volumes. There are no restrictions
on which optical commands the system supports for the HPOFS media.</dd>
</dl>
<dl><dt class="dlterm">UDF</dt>
<dd>i5/OS save
and restore commands can be used to save and restore data on UDF optical media.
There are some restrictions on which optical commands are supported to UDF
volumes. For example, the system does not support Work with Optical Directories
(WRKOPTDIR) and Work with Optical Files (WRKOPTF) commands. The Display Optical
(DSPOPT) command has some restrictions when used for UDF volumes. You should
use the integrated file system commands Work with Object Links (WRKLNK) and
Display Object Links (DSPLNK) instead of the optical commands.</dd>
</dl>
</div>
<p>Some optical commands have no meaning when used with certain optical media
formats. No support exists for other commands with certain optical media formats.
This table lists all of the volume-related optical commands and the media
formats to which they apply.</p>
