Guidelines and Limitations

</h1>
<a name="wp1126138"> </a><p class="pBody">
Before scheduling jobs on a Cisco MDS 9000 switch, note the following guidelines: 

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1126139"> </a><li class="pSmartList1">Prior to Cisco MDS SAN-OS Release 3.0(3), only users local to the switch could perform scheduler 
configuration. As of Cisco MDS SAN-OS Release 3.0(3), remote users can perform job scheduling 
using AAA authentication.
</li>
<a name="wp1126140"> </a><li class="pSmartList1">Be aware that the scheduled job can fail if it encounters one of the following situations when 
executing the job:
</li>
<div class="pSmartList2"><ul class="pSmartList2">
<a name="wp1126141"> </a><li class="pSmartList2">If the license has expired for a feature at the time when a job containing commands pertaining to that feature is scheduled.</li>
<a name="wp1126142"> </a><li class="pSmartList2">If a feature is disabled at the time when a job containing commands pertaining to that feature is scheduled. </li>
<a name="wp1126143"> </a><li class="pSmartList2">If you have removed a module from a slot and the job has commands pertaining to the interfaces for that module or slot.</li>
</ul></div>
<a name="wp1126144"> </a><li class="pSmartList1">Verify that you have configured the time. The scheduler does not have any default time configured. 
If you create a schedule and assign job(s) and do not configure the time, that schedule is not 
launched.
</li>
<a name="wp1126145"> </a><li class="pSmartList1">While defining a job, verify that no interactive or disruptive commands (for example, <b class="cBold">copy 
bootflash:</b> <em style="font-style: italic; font-weight: normal">file</em> <b class="cBold">ftp:</b> <em style="font-style: italic; font-weight: normal">URI</em>,<b class="cBold"> write erase</b>, and other similar commands) are specified as part of a job 
because the job is executed noninteractively at the scheduled time.
</li>
</ul></div>
