It is in this mode until the server reboots. In Write Through mode, the controller sends a data transfer completion signal to the host when the disk subsystem has received all of the data in a transaction. This way, in case of a power outage, the controller does not discard the dirty cache.</a></p> <p class="Body"><a name="3_26_3_1_4">Follow these steps to upgrade the firmware:</a></p> <div class="Step_1_outer" style="margin-left: 1px"> <table border="0" cellspacing="0" cellpadding="0" summary="" role="presentation"> <tr style="vertical-align: baseline"> <td> <p class="Step_1_inner" style="width: 18pt; white-space: nowrap">1. </p> </td> <td width="100%"> <p class="Step_1_inner"><span class="Command"><a name="3_26_3_2_1">In the left panel of the </a></span><span class="wintitle">MegaRAID Storage Manager</span><span class="Command"> window, click the icon of the controller you want to upgrade.</span></p> </td> </tr> </table> </div> <div class="Step_1_outer" style="margin-left: 1px"> <table border="0" cellspacing="0" cellpadding="0" summary="" role="presentation"> <tr style="vertical-align: baseline"> <td> <p class="Step_1_inner" style="width: 18pt; white-space: nowrap">2. </p> </td> <td width="100%"> <p class="Step_1_inner"><span class="Command"><a name="3_26_3_2_2">In the </a></span><span class="wintitle">MegaRAID Storage Manager</span><span class="Command"> window, select </span><span class="uicontrol">Go To > Controller > Update Controller Firmware</span><span class="Command">.</span></p> </td> </tr> </table> </div> <div class="Step_1_outer" style="margin-left: 1px"> <table border="0" cellspacing="0" cellpadding="0" summary="" role="presentation"> <tr style="vertical-align: baseline"> <td> <p class="Step_1_inner" style="width: 18pt; white-space: nowrap">3. </p> </td> <td width="100%"> <p class="Step_1_inner"><span class="Command"><a name="3_26_3_2_3">Click </a></span><span class="uicontrol">Browse</span><span class="Command"> to locate the </span><span class="filepath">.rom</span><span class="Command"> update file, as shown in the following figure.</span></p> </td> </tr> </table> </div> <p class="Figure_Title">Figure 77. <a name="3_26_3_2_3_4_2_2">Update Controller Firmware Dialog</a></p> <p class="Figure_1"><a name="3_26_3_2_3_4_2-2"><img class="Default" src="images/NDM_Figure_153_Update_Controller_Firmware.png" width="461" height="270" style="display: inline; float: none; left: 0pt; top: 0pt" alt="" /></a></p> <div class="Step_1_outer" style="margin-left: 1px"> <table border="0" cellspacing="0" cellpadding="0" summary="" role="presentation"> <tr style="vertical-align: baseline"> <td> <p class="Step_1_inner" style="width: 18pt; white-space: nowrap">4. </p> </td> <td width="100%"> <p class="Step_1_inner"><span class="Command"><a name="3_26_3_2_4">After you locate the file, click </a></span><span class="uicontrol">Ok</span><span class="Command">.</span></p> </td> </tr> </table> </div> <p class="Body_1"><a name="3_26_3_2_4_4_2">The MegaRAID Storage Manager software displays the version of the existing firmware and the version of the new firmware file.</a></p> <div class="Step_1_outer" style="margin-left: 1px"> <table border="0" cellspacing="0" cellpadding="0" summary="" role="presentation"> <tr style="vertical-align: baseline"> <td> <p class="Step_1_inner" style="width: 18pt; white-space: nowrap">5. </p> </td> <td width="100%"> <p class="Step_1_inner"><span class="Command"><a name="3_26_3_2_5">When you are prompted to indicate whether you want to upgrade firmware, click </a></span><span class="uicontrol">Yes</span><span class="Command">.</span></p> </td> </tr> </table> </div> <p class="Body_1"><a name="3_26_3_2_5_4_2">The controller is updated with the new firmware code contained in the </a><span class="filepath">.rom</span> file.</p> <div class="Step_1_outer" style="margin-left: 1px"> <table border="0" cellspacing="0" cellpadding="0" summary="" role="presentation"> <tr style="vertical-align: baseline"> <td> <p class="Step_1_inner" style="width: 18pt; white-space: nowrap">6. </p> </td> <td width="100%"> <p class="Step_1_inner"><span class="Command"><a name="3_26_3_2_6">Restart the system after the new firmware is flashed.</a></span></p> </td> </tr> </table> </div> <p class="Body_1"><a name="3_26_3_2_6_4_2">The new firmware does not take effect until you restart the system.</a></p> <script type="text/javascript" language="JavaScript1.2"> <!-- // Clear related topics // WWHClearRelatedTopics(); document.writeln(WWHRelatedTopicsInlineHTML()); // --> </script> </blockquote> <hr align="left" /> <!-- LSI changed location of company info to align left --> <!-- Added rol from 2011.3 pages.asp file --> <!-- LSI added copyright style --> <!-- --> <table align="left" role="presentation"> <!-- LSI added support for booknum and reldate --> <!-- --> <tr> <td class="copyright">DB15-001059-00-April 2013</td> </tr> <tr> <td class="copyright"> <a href="http://www.lsi.com/Pages/trademark.aspx?" target="external_window">Copyright© 2013 by LSI Corporation.
