|
|
<div><p>Use this information to change the access-mode for virtual optical
|
|
media.</p>
|
|
<p>All image catalog entries include a write-protect switch, which functions
|
|
identically to the write-protect switch on actual media. The initial position
|
|
of this switch is on for read-only media and off for writable media. Virtual
|
|
images in International Standards Organization (ISO) 9660 format are read-only
|
|
while media in universal disk format (UDF) can be writable or read-only.</p>
|
|
<p>When you add a new image catalog entry to an image catalog, the image catalog
|
|
entry is not write-protected by default. After you add an image catalog entry
|
|
to an image catalog, you can change whether it is write-protected with the
|
|
Change Image Catalog Entry (CHGIMGCLGE) command.</p>
|
|
<p>To change an image catalog entry to be write-protected, type the following
|
|
command, where the image catalog name is MYCAT and the image catalog index
|
|
is 3:</p>
|
|
<pre> CHGIMGCLGE IMGCLG(MYCAT) IMGCLGIDX(3) WRTPTC(*YES)</pre>
|
|
<p>To change a write-protected image catalog entry's write-protection status
|
|
to not write-protected, type the following command where the image catalog
|
|
name is MYCAT and the image catalog index is 3:</p>
|
|
<pre> CHGIMGCLGE IMGCLG(MYCAT) IMGCLGIDX(3) WRTPTC(*NO)</pre>
