<div class="section"> <p>Tape data files can be extended using the EXTEND parameter on the CRTTAPF, CHGTAPF, and OVRTAPF
|
||
|
|
commands. The system does not support extending tape devices that do not support
|
||
|
|
overwrite capability.</p>
|
||
|
|
<p>When you extend a file, any existing tape data
|
||
|
|
following the specified file on the tape is no longer accessible by the system.</p>
|
||
|
|
<p>In
|
||
|
|
the following example, a tape contains four files: FILE1, FILE2, FILE3, and FILE4. If
|
||
|
|
FILE2 is extended, FILE3 and FILE4 are no longer accessible.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> If
|
||
|
|
you specify EXTEND(*YES *CHECK) on the OVRTAPF command, the expiration date
|
||
|
|
of the file <span>(FILE3)</span> that is following the extension of <span>(FILE2)</span> is
|
||
|
|
checked. <span>The expiration date will be checked</span> <em>before</em> extending
|
||
|
|
the file (FILE2). However, the expiration dates of any remaining files (FILE4)
|
||
|
|
are not checked, even if EXTEND(*YES *CHECK) is specified.</div>
