These files are in the path <code>/etc/udev/rules.d/</code>. Rules files are read in lexical order. For example, rules in the file <code>10-wacom.rules</code> are parsed and carried out before rules in the file <code>90-ib.rules</code>.</p> <p>On Oracle Enterprise Linux 5, if two or more rules files describe the same devices, then the last file read is the one that is applied.</p> <a id="TDPRC158" name="TDPRC158"></a> <p class="subhead2">To create a rules file for shared disk devices, complete the following tasks:</p> <ol> <li> <p>On each node in the cluster, create a rules file in <code>/etc/udev/rules.d</code>, to set the ownership and permissions for the Oracle Clusterware files. The contents of the <code>99-oracle.rules</code> file are as follows:</p> <p>ASM disks, where <code>oracle</code> is the installation user:</p> <pre xml:space="preserve" class="oac_no_warn"> device_partition:oracle:dba:0660 </pre> <p>For example, to specify rules for the disk device /dev/sda, which is used by an ASM disk group, create the following entry:</p> <pre xml:space="preserve" class="oac_no_warn"> sda:oracle:dba:0660 </pre></li> <li> <p>Specify the device name for each storage location you configured previously.</p> </li> <li> <p>As the <code>root</code> user, enter the commands to restart the UDEV service on each node in the cluster. On Oracle Enterprise Linux 5.0 the commands are:</p> <pre xml:space="preserve" class="oac_no_warn"> # udevcontrol reload_rules # start_udev </pre></li> </ol> </div> <!-- class="sect3" --> <!-- class="sect2" --> <!-- class="sect1" --> <!-- Start Footer --> <div class="footer"> <table class="simple oac_no_warn" summary="" cellspacing="0" cellpadding="0" width="100%"> <col width="86%" /> <col width="*" /> <tr> <td align="left"><span class="copyrightlogo">Copyright © 2006, 2009, Oracle and/or its affiliates.
