<div>If you have a drac, it should either be visible with the OpenManage interface, commands, or as a 10/100 port on the far left of the back of the server; and also should give you a setup screen during bootup. If you don't have one though, you can still use ipmi fencing to the on-board BMC/ESM card. We've found the only real drawback to this is that sometimes the ipmi fencing may have difficulty communicating to a locked up host or a host which has kernel panic'd.</div> <div>The drac is better though, as it allows for ssh and full power-off/power-on functionality. Also, if your drac is a drac5 and has firmware greater than 1.20 on it (such as 1.33), you'll need to use the fence_drac5 module which is included but not fully documented. </div> <div class="gmail_quote">On Tue, Aug 11, 2009 at 11:39 AM, <<a href="mailto:bergman@merctech.com">bergman@merctech.com</a>> wrote: <blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote"> In the message dated: Tue, 11 Aug 2009 14:14:03 +0200, The pithy ruminations from Juan Ramon Martin Blanco on <Re: [Linux-cluster] do I have a fence DRAC device?> were: => --===============1917368601== => Content-Type: multipart/alternative; boundary=0016364c7c07663f600470dca3b8 => => --0016364c7c07663f600470dca3b8 => Content-Type: text/plain; charset=ISO-8859-1 => Content-Transfer-Encoding: quoted-printable => <div class="im">=> On Tue, Aug 11, 2009 at 2:03 PM, ESGLinux <<a href="mailto:esggrupos@gmail.com">esggrupos@gmail.com</a>> wrote: => => > Thanks </div>=> > I=B4ll check it when I could reboot the server. <div class="im">=> > => > greetings, => > => You have a BMC ipmi in the first network interface, it can be configured at => boot time (I don't remember if inside the BIOS or pressing cntrl+something => during boot) </div>=> Based on my notes, here's how I configured the DRAC interface on a Dell 1950 for use as a fence device: Configuring the card from Linux depending on the installation of Dell's OMSA package.
