[Linux-cluster] fence_ipmilan

[jose nuno neto]

Hi

Sorry for not posting the info before....
I repeated the steps, and now fence_ipmilan -o reboot powers down the
machine, no power up, and ILOm gets reseted to factory defaults ????

Below is the info, I've been finding the fence_ipmilan not very reliable,
any one using it in prod? what is the most used fencing methods?
