The pithy ruminations from Digimer <linux@xxxxxxxxxxx> on " Tripp Lite switched PDU fence agent; exists?" were: => Hi all, => => Does anyone know if the tripp lite (mn: PDUMH15ATNET, specifically) => has an existing RHCS fence agent? Specifically for cluster 2 / EL5.5. If Yes. => not, has anyone written one? Failing all that, I suppose I will write => one. :) => Yes. I wrote an agent for that piece of hardware and offered the agent to the RHCS community in Nov 2008...there was no response at the time.[1] In March, 2009, I sent a copy of the agent script to Jan Friesse <jfriesse@xxxxxxxxxx>, Marek Grac <mgrac@xxxxxxxxxx>, who were identified as the maintainers of all the fence agents. Since it apparently hasn't made it into the RHCS distribution, let me know if you want a copy. Finally, I'd like to warn people away from using the TrippLite PDU model PDUMH15ATNET as a fencing device. While it seems to have nice features, it has a design choice that is a serious problem with fencing--when a command is given to power down an outlet, there is a "random" delay (observed to be about 17 to 35 seconds) before that command is executed. This has been acknowledged by TrippLite support as a design choice, with no option or setting to override this behavior.
