Description of problem: There is a problem with current ILO fencing agent. It is unable to power on the machine. Solution: instead of sendsock $socket, "<HOLD_PWR_BTN/>\n"; I put sendsock $socket, "<HOLD_PWR_BTN TOGGLE=\"Yes\"/>\n";
Do you know what revision of the firmware is having a problem with the current agent, and do you know whether it's iLO or iLO2? Depending on the combination of the two, the command and parameters needed to power on the machine differs. Adding the TOGGLE="Yes" attribute will break a lot of combinations of ilo/firmware revisions. FWIW, the current fencing agent works properly for me on the latest iLO firmware (1.91) and 1.82; and firmware 1.43 (dated 2007-12-12 -- not sure if this is the latest) on iLO2.
