Hello, As fence_idrac has never worked for us, and as fence_ipmilan has worked nicely since years, we are using fence_ipmilan with the lanplus=1 option and we're happy with it. We upgraded to 4.3.0.4 and we're witnessing that we cannot fence our hosts anymore : 2019-02-18 09:42:08,678+01 ERROR [org.ovirt.engine.core.bll.pm.FenceProxyLocator] (default task-11) [2f78ed99-6703-4d92-b7cb-948c2d24b623] Can not run fence action on host 'xxxxx', no suitable proxy host was found. and on the SPM : fence_ipmilan: Failed: Unable to obtain correct plug status or plug is not available I found the suggested workaround here : https://access.redhat.com/solutions/3349841 but no combination of - lanplus={0,1} - -z - ssl=={0,1} lead to no solution. The package version is the same as what's described in the KB : fence-agents-rhevm-4.2.1-11.el7_6.7.x86_64 What should I test now? Thank you. -- Nicolas ECARNOT
