Hi, i'm currently establishing a two node cluster. Each node is a HP server with an ILO card. I can fence both of them, it's working fine. But what is if the ILO does not work correctly ? Then fencing is not possible.
I also have a switched PDU from APC. Each server has two power supplies. Currently one is connected to the normal power equipment, the other to the UPS. As a sort of redundancy, if the UPS does not work properly. When i'd like to use the switched PDU as a fencing device i will loose the redundancy of two independent power sources, because then i have to connect both power supplies together to the UPS. I wouldn't like to do that. How important would you consider to have two independent fencing device for each node ? I'd can't by another PDU, currently we are very poor. Is there another way to create a second fencing device, independent from the ILO card ? Thanks.
