Hello all, I´m configuring a 2 nodes cluster on 2 servers HP Proliant DL165 G5 This servers have HP ProLiant Lights-Out 100 Remote Management and I want to use it as fencing device. My first idea was to configure them with IPMI and it works almost fine but I have detected that when I have the network down, the fence devices doesn't work because the nodes can't reach the othe node to fence it. I have tried with a dedicated switch and a direct cable but it doesn't work and I begin to think I´m doing something wrong because the interface with the ipmi configured doesnt appear on the servers. I´ll try to explain: I have node1 eth0: IP1 eth1: IP2 In the bios I have configured ethMng : IP3 node2 eth0: IP4 eth1: IP5 In the bios I have configured ethMng : IP6 with the network up all works fine and I can use fence_node to fence the nodes, and the cluster works fine. But, if I disconnect IP1, IP2, IP3, IP4 (This simulate a switch fail) I expect the cluster become fencing with IP3 and IP6 but the system doesn't find these IP´s and all the cluster hungs. Looking the fence devices avaliable with conga I have seen that there is one called: <table><tbody><tr><td> </td> <td>HP iLO</td></tr></tbody></table>with this parameters to configure: Name Hostname Login Password Password Script (optional) All are self explanatory but I don´t know what to put on Hostname (which hostname? the same machine, the other? FQDN.. IP....) So, I have 2 questions: If I use IPMI what I´m doing wrong? and If I use HP iLO, what I need to configure??? any idea, manual, doc, suggest.... is welcome thanks in advance ESG
