|

|
|
<div><p>This industry standard media format was originally designed to
|
||
|
|
specify the volume and file structures of compact-disk read-only memory (CD-ROM)
|
||
|
|
optical disks, and is a read-only media format.</p>
|
||
|
|
<p> The ISO 9660 format is used currently on CD and DVD read only media. i5/OS™ supports
|
||
|
|
ISO 9660 media that is created using the primary volume descriptor (PVD). i5/OS does
|
||
|
|
not support ISO 9660 extensions that use the supplementary volume descriptor
|
||
|
|
(SVD). </p>
|
||
|
|
<p>In addition, there is some support for ISO 9660 extensions defined as the
|
||
|
|
IEEE P1281 (System Use Sharing Protocol) and P1282 (Rock Ridge Interchange
|
||
|
|
Protocol) specifications. These extensions are also known as Rock Ridge. i5/OS supports
|
||
|
|
the Rock Ridge alternate name structures through the PVD. This support provides
|
||
|
|
recognition and handling of mixed case and long file names, similar to a UNIX<sup>®</sup> system.
|
||
|
|
Other structures defined by Rock Ridge are not supported by i5/OS. To enable
|
||
|
|
support to read Rock Ridge alternate name structure (if it exists), enter
|
||
|
|
CHGOPTA EXTMEDFMT(*YES) prior to importing the media. If the Rock Ridge alternate
|
||
|
|
name structures do not exist, entering this command will have no effect.</p>
