<p>Either the threshold is incorrectly set, the object being stored is bigger
|
||
|
|
than the available space, or the <em>spares area</em> is full. Display the volume
|
||
|
|
attributes of the volume that you are writing to using the <span class="cmdname">display
|

|
|
optical</span> (DSPOPT) command. Verify that the threshold and space available
|
||
|
|
values are valid. Also, verify that access to the volume access is <em>writeable</em>,
|
||
|
|
and not <em>read only</em>. If it is read only, then the spares area may be
|

full. The spares area is a set of sectors to which data is written when the

<p>Several situations could cause this to happen:</p>

|
<ul><li>Device errors may have occurred when only part of a file was written.
|
||
|
|
When the backup operation was restarted, the complete file was rewritten.</li>
|
||
|
|
<li>If the backup volume type is WORM, it might have been initialized multiple
|
||
|
|
times before the backup operation, thus wasting some volume space.</li>
|
||
|
|
<li>If you are performing an incremental backup operation, you might have
|
||
|
|
selected the wrong option on the SLTFILE parameter (*ALL instead of *CHANGED).</li>
|
||
|
|
<li>If you created the primary volume on a pre-Version 2 Release 3 Modification
|
||
|
|
0 system, and the primary volume is over 98% full, then the Duplicate Optical
|
||
|
|
(DUPOPT) command may be the only choice to back up this volume.</li>
